There are a large number of microscopes based on the physical principle used to produce an image and based on their area of application. The type of instruments we supply are OPTICAL MICROSCOPES (COMPOUND / STEREO TYPES), and METALLURGICAL MICROSCOPES. You can purchase brand new as well as refurbished or used equipment from us. Browse through our catalogs below and let us know the brand and model number and we will provide you our offers: HAIDA Color Assessment Cabinet SADT-SINOAGE Brand Metrology and Test Equipment Catalog In this catalog you will find some high quality metallurgical microscopes and inverted microscopes. SINOWON Instant Vision Measuring System SINOWON Profile Projector SINOWON Toolmakers Microscope SINOWON Vision Measuring Machine SINOWON Video Microscope We offer both FLEXIBLE and RIGID FIBERSCOPE and BORESCOPE models and they are primarily used for NONDESTRUCTIVE TESTING in confined spaces, like crevices in some concrete structures and aircraft engines. Both of these optical instruments are used for visual inspection. There are however differences between fiberscopes and borescopes: One of them is the flexibility aspect. Fiberscopes are made of flexible optic fibers and have a viewing lens attached to their head. The operator can turn the lens after insertion of the fiberscope into a crevice. This increases the operator’s view. To the contrary, borescopes are generally rigid and allow the user to view only straight ahead or at right angles. Another difference is the light source. A fiberscope does transmit light down its optical fibers to illuminate the observation area. On the other hand, a borescope has mirrors and lenses so light can be bounced from between mirrors to illuminate the observation area. Lastly, the clarity is different. Whereas fiberscopes are limited to a range of 6 to 8 inches, borescopes can provide a wider and clearer view as compared to fiberscopes. OPTICAL MICROSCOPES : These optical instruments use visible light (or UV light in the case of fluorescence microscopy) to produce an image. Optical lenses are used to refract the light. The first microscopes that were invented were optical. Optical microscopes can be further subdivided into several categories. We focus our attention to two of them: 1.) COMPOUND MICROSCOPE : These microscopes are composed of two lens systems, an objective and an ocular (eye piece). The maximum useful magnification is about 1000x. 2.) STEREO MICROSCOPE (also known as DISSECTING MICROSCOPE): These microscopes magnify to about maximum 100x and supply a 3D view of the specimen. They are useful for observing opaque objects. METALLURGICAL MICROSCOPES : Our downloadable SADT catalog with the link above does contain metallurgical and inverted metallographic microscopes. So please see our catalog for product details. In order to acquire a basic understanding about these types of microscopes, please go to our page COATING SURFACE TEST INSTRUMENTS. FIBERSCOPES : Fiberscopes incorporate fiber optic bundles, consisting of numerous fiber optic cables. Fiber optic cables are made of optically pure glass and are as thin as a human’s hair. The main components to a fiber optic cable are: Core, which is the center made of high purity glass, cladding which is he outer material surrounding the core that prevents light from leaking and finally buffer which is the protective plastic coating. Generally there are two different fiber optic bundles in a fiberscope: The first one is the illumination bundle which is designed to carry light from the source to the eyepiece and the second one is the imaging bundle designed to carry an image from the lens to the eyepiece. A typical fiberscope is made up of the following components: -Eyepiece: This is the part from where we observe the image. It magnifies the image carried by the imaging bundle for easy viewing. -Imaging Bundle: A strand of flexible glass fibers transmitting the images to the eyepiece. -Distal Lens: A combination of multiple micro lenses that take images and focus them into the small imaging bundle. -Illumination System: A Fiber optic light guide that sends light from the source to the target area (eyepiece) -Articulation System: The system providing the user the ability to control the movement of the bending section of the fiberscope that is directly attached to the distal lens. -Fiberscope Body: The control section designed to help one hand operation. -Insertion Tube: This flexible and durable tube protects the fiber optic bundle and articulation cables. -Bending Section – The most flexible part of the fiberscope connecting the insertion tube to the distal viewing section. -Distal Section: ending location for both the illumination and imaging fiber bundle. BORESCOPES / BOROSCOPES : A borescope is an optical device consisting of a rigid or flexible tube with an eyepiece on one end, and an objective lens on the other end linked together by a light transmitting optical system in between. Optical fibers surrounding the system are generally used for illuminating the object to be viewed. An internal image of the illuminated object is formed by the objective lens, magnified by the eyepiece and presented to the viewer's eye. Many modern borescopes can be fitted with imaging and video devices. Borescopes are used similar to fiberscopes for visual inspection where the area to be inspected is inaccessible by other means. Borescopes are considered nondestructive test instruments for viewing and examining defects and imperfections. The areas of application is only limited by your imagination. The term FLEXIBLE BORESCOPE is sometimes used interchangeably with the term fiberscope. One disadvantage for flexible borescopes originates from pixelation and pixel crosstalk due to the fiber image guide. Image quality varies widely among different models of flexible borescopes depending on the number of fibers and construction used in the fiber image guide. High end borescopes offer a visual grid on image captures that aids in evaluating the size of the area under inspection. For flexible borescopes, articulation mechanism components, range of articulation, field of view and angles of view of the objective lens are also important. Fiber content in the flexible relay is also critical to provide the highest possible resolution. Minimal quantity is 10,000 pixels while the best images are obtained with higher numbers of fibers in the 15,000 to 22,000 pixels range for the larger diameter borescopes. The ability to control the light at the end of the insertion tube allows the user to make adjustments that can significantly improve the clarity of images taken. On the other hand, RIGID BORESCOPES generally provide a superior image and lower cost compared to a flexible borescope. The shortcoming of rigid borescopes is the limitation that access to what is to be viewed must be in a straight line. Therefore, rigid borescopes have a limited area of application. For similar-quality instruments, the largest rigid borescope that will fit the hole gives the best image. A VIDEO BORESCOPE is similar to the flexible borescope but uses a miniature video camera at the end of the flexible tube. The end of the insertion tube includes a light which makes it possible to capture video or still images deep within the area of investigation. The ability of video borescopes to capture video and still images for later inspection is very useful. Viewing position can be changed via a joystick control and displayed on the screen mounted on its handle. Because the complex optical waveguide is replaced with an inexpensive electrical cable, video borescopes can be much less costly and potentially offer better resolution. Some borescopes offer USB cable connection.

In other words, it refers to laboratory techniques for the separation of mixtures. The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds, which causes them to separate. The separation is based on differential partitioning between the mobile and stationary phases. Small differences in partition coefficient of a compound results in differential retention on the stationary phase and thus changing the separation. Chromatography can be used to separate the components of a mixture for more advanced use such as purification) or for measuring the relative proportions of analytes (which is the substance to be separated during chromatography) in a mixture. Several chromatographic methods exist, such as paper chromatography, gas chromatography and high performance liquid chromatography. ANALYTICAL CHROMATOGRAPHY is used to determine the existence and the concentration of analyte(s) in a sample. In a chromatogram different peaks or patterns correspond to different components of the separated mixture. In an optimal system each signal is proportional to the concentration of the corresponding analyte that was separated. An equipment called CHROMATOGRAPH enables a sophisticated separation. There are specialized types according to the physical state of the mobile phase such as GAS CHROMATOGRAPHS and LIQUID CHROMATOGRAPHS. Gas chromatography (GC), also sometimes called gas-liquid chromatography (GLC), is a separation technique in which the mobile phase is a gas. High temperatures used in Gas Chromatographs make it unsuitable for high molecular weight biopolymers or proteins encountered in biochemistry because heat denatures them. The technique is however well suited for use in the petrochemical, environmental monitoring, chemical research and industrial chemical fields. On the other hand, Liquid Chromatography (LC) is a separation technique in which the mobile phase is a liquid. In order to measure the characteristics of individual molecules, a MASS SPECTROMETER converts them to ions so that they can be accelerated, and moved about by external electric and magnetic fields. Mass spectrometers are used in Chromatographs explained above, as well as in other analysis instruments. The associated components of a typical mass spectrometer are: Ion Source: A small sample is ionized, usually to cations by loss of an electron. Mass Analyzer: The ions are sorted and separated according to their mass and charge. Detector: The separated ions are measured and results displayed on a chart. Ions are very reactive and short-lived, therefore their formation and manipulation must be conducted in a vacuum. The pressure under which ions may be handled is roughly 10-5 to 10-8 torr. The three tasks listed above may be accomplished in different ways. In one common procedure, ionization is effected by a high energy beam of electrons, and ion separation is achieved by accelerating and focusing the ions in a beam, which is then bent by an external magnetic field. The ions are then detected electronically and the resulting information is stored and analyzed in a computer. The heart of the spectrometer is the ion source. Here molecules of the sample are bombarded by electrons emanating from a heated filament. This is called an electron source. Gases and volatile liquid samples are allowed to leak into the ion source from a reservoir and non-volatile solids and liquids may be introduced directly. Cations formed by the electron bombardment are pushed away by a charged repeller plate (anions are attracted to it), and accelerated toward other electrodes, having slits through which the ions pass as a beam. Some of these ions fragment into smaller cations and neutral fragments. A perpendicular magnetic field deflects the ion beam in an arc whose radius is inversely proportional to the mass of each ion. Lighter ions are deflected more than heavier ions. By varying the strength of the magnetic field, ions of different mass can be focused progressively on a detector fixed at the end of a curved tube under a high vacuum. A mass spectrum is displayed as a vertical bar graph, each bar representing an ion having a specific mass-to-charge ratio (m/z) and the length of the bar indicates the relative abundance of the ion. The most intense ion is assigned an abundance of 100, and it is referred to as the base peak. Most of the ions formed in a mass spectrometer have a single charge, so the m/z value is equivalent to mass itself. Modern mass spectrometers have very high resolutions and can easily distinguish ions differing by only a single atomic mass unit (amu). A RESIDUAL GAS ANALYZER (RGA) is a small and rugged mass spectrometer. We have explained mass spectrometers above. RGAs are designed for process control and contamination monitoring in vacuum systems such as research chambers, surface science setups, accelerators, scanning microscopes. Utilizing quadrupole technology, there are two implementations, utilizing either an open ion source (OIS) or a closed ion source (CIS). RGAs are used in most cases to monitor the quality of the vacuum and easily detect minute traces of impurities possessing sub-ppm detectability in the absence of background interferences. These impurities can be measured down to (10)Exp -14 Torr levels, Residual Gas Analyzers are also used as sensitive in-situ, helium leak detectors. Vacuum systems require checking of the integrity of the vacuum seals and the quality of the vacuum for air leaks and contaminants at low levels before a process is initiated. Modern residual gas analyzers come complete with a quadrupole probe, electronics control unit , and a real-time Windows software package that is used for data acquisition and analysis, and probe control. Some software supports multiple head operation when more than one RGA is needed. Simple design with a small number of parts will minimize outgassing and reduce the chances of introducing impurities into your vacuum system. Probe designs using self-aligning parts will ensure easy reassembled after cleaning. LED indicators on modern devices provide instant feedback on the status of the electron multiplier, filament, electronics system and the probe. Long-life, easily changeable filaments are used for electron emission. For increased sensitivity and faster scan rates, an optional electron multiplier is sometimes offered that detects partial pressures down to 5 × (10)Exp -14 Torr. Another attractive feature of residual gas analyzers is the built-in degassing feature. Using electron impact desorption, the ion source is thoroughly cleaned, greatly reducing the ionizer's contribution to background noise. With a large dynamic range the user can make measurements of small and large gas concentrations simultaneously. A MOISTURE ANALYZER determines the remaining dry mass after a drying process with infrared energy of the original matter which is previously weighed. Humidity is calculated in relation to the weight of the wet matter. During the drying process, the decrease of moisture in the material is shown on the display. The moisture analyzer determines moisture and the amount of dry mass as well as the consistency of volatile and fixed substances with high accuracy. The weighing system of the moisture analyzer possesses all the properties of modern balances. These metrology tools are used in the industrial sector to analyze pastes, wood, adhesive materials, dust,…etc. There are many applications where trace moisture measurements are necessary for manufacturing and process quality assurance. Trace moisture in solids must be controlled for plastics, pharmaceuticals and heat treatment processes. Trace moisture in gases and liquids need to be measured and controlled as well. Examples include dry air, hydrocarbon processing, pure semiconductor gases, bulk pure gases, natural gas in pipelines….etc. The loss on drying type analyzers incorporate an electronic balance with a sample tray and surrounding heating element. If the volatile content of the solid is primarily water, the LOD technique gives a good measure of moisture content. An accurate method for determining the amount of water is the Karl Fischer titration, developed by the German chemist. This method detects only water, contrary to loss on drying, which detects any volatile substances. Yet for natural gas there are specialized methods for the measurement of moisture, because natural gas poses a unique situation by having very high levels of solid and liquid contaminants as well as corrosives in varying concentrations. MOISTURE METERS are test equipment for measuring the percentage of water in a substance or material. Using this information, workers in various industries determine if the material is ready for use, too wet or too dry. For example, wood and paper products are very sensitive to their moisture content. Physical properties including dimensions and weight are strongly affected by moisture content. If you are purchasing large quantities of wood by weight, it will be a wise thing to measure the moisture content to make sure it is not intentionally watered to increase the price. Generally two basic types of moisture meters are available. One type measures the electrical resistance of the material, which becomes increasingly lower as the moisture content of it rises. With the electrical resistance type of moisture meter, two electrodes are driven into the material and the electrical resistance is translated into moisture content on the device’s electronic output. A second type of moisture meter relies on the dielectric properties of the material, and requires only surface contact with it. The ANALYTICAL BALANCE is a basic tool in quantitative analysis, used for the accurate weighing of samples and precipitates. A typical balance should be able to determine differences in mass of 0.1 milligram. In microanalyses the balance must be about 1,000 times more sensitive. For special work, balances of even higher sensitivity are available. The measuring pan of an analytical balance is inside a transparent enclosure with doors so that dust does not collect and air currents in the room do not affect the balance's operation. There is a smooth turbulence-free airflow and ventilation that prevents balance fluctuation and the measure of mass down to 1 microgram without fluctuations or loss of product. Maintaining consistent response throughout the useful capacity is achieved by maintaining a constant load on the balance beam, thus the fulcrum, by subtracting mass on the same side of the beam to which the sample is added. Electronic analytical balances measure the force needed to counter the mass being measured rather than using actual masses. Therefore they must have calibration adjustments made to compensate for gravitational differences. Analytical balances use an electromagnet to generate a force to counter the sample being measured and outputs the result by measuring the force needed to achieve balance. SPECTROPHOTOMETRY is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength, and SPECTROPHOTOMETER is the test equipment used for this purpose. The spectral bandwidth (the range of colors it can transmit through the test sample), the percentage of sample-transmission, the logarithmic range of sample-absorption and percentage of reflectance measurement are critical for spectrophotometers. These test instruments are widely used in optical component testing where optical filters, beam splitters, reflectors, mirrors…etc need to be evaluated for their performance. There are many other applications of spectrophotometers including the measurement of transmission and reflection properties of pharmaceutical and medical solutions, chemicals, dyes, colors……etc. These tests ensure consistency from batch to batch in production. A spectrophotometer is able to determine, depending on the control or calibration, what substances are present in a target and their quantities through calculations using observed wavelengths. The range of wavelengths covered is generally between 200 nm - 2500 nm using different controls and calibrations. Within these ranges of light, calibrations are needed on the machine using specific standards for the wavelengths of interest. There are two major types of spectrophotometers, namely single beam and double beam. Double beam spectrophotometers compare the light intensity between two light paths, one path containing a reference sample and the other path containing the test sample. A single-beam spectrophotometer on the other hand measures the relative light intensity of the beam before and after a test sample is inserted. Although comparing measurements from double-beam instruments are easier and more stable, single-beam instruments can have a larger dynamic range and are optically simpler and more compact. Spectrophotometers can be installed also into other instruments and systems which can help users to perform in-situ measurements during production…etc. The typical sequence of events in a modern spectrophotometer can be summarized as: First the light source is imaged upon the sample, a fraction of the light is transmitted or reflected from the sample. Then the light from the sample is imaged upon the entrance slit of the monochromator, which separates the wavelengths of light and focuses each of them onto the photodetector sequentially. The most common spectrophotometers are UV & VISIBLE SPECTROPHOTOMETERS which operate in the ultraviolet and 400–700 nm wavelength range. Some of them cover the near-infrared region too. On the other hand, IR SPECTROPHOTOMETERS are more complicated and expensive because of the technical requirements of measurement in the infrared region. Infrared photosensors are more valuable and Infrared measurement is also challenging because almost everything emits IR light as thermal radiation, especially at wavelengths beyond about 5 m. Many materials used in other types of spectrophotometers such as glass and plastic absorb infrared light, making them unfit as the optical medium. Ideal optical materials are salts such as potassium bromide, which do not absorb strongly. A POLARIMETER measures the angle of rotation caused by passing polarized light through an optically active material. Some chemical materials are optically active, and polarized (unidirectional) light will rotate either to the left (counter-clockwise) or right (clockwise) when passed through them. The amount by which the light is rotated is called the angle of rotation. One popular application, concentration and purity measurements are made to determine product or ingredient quality in the food, beverage and pharmaceutical industries. Some samples that display specific rotations that can be calculated for purity with a polarimeter include the Steroids, Antibiotics, Narcotics, Vitamins, Amino Acids, Polymers, Starches, Sugars. Many chemicals exhibit a unique specific rotation which can be used to distinguish them. A Polarimeter can identify unknown specimens based on this if other variables like concentration and length of sample cell are controlled or at least known. On the other hand, if the specific rotation of a sample is already known, then the concentration and/or purity of a solution containing it can be calculated. Automatic polarimeters calculate these once some input on variables are entered by the user. A REFRACTOMETER is a piece of optical test equipment for the measurement of index of refraction. These instruments measure the extent to which light is bent, i.e. refracted when it moves from air into the sample and are typically used to determine the refractive index of samples. There are five types of refractometers: traditional handheld refractometers, digital handheld refractometers, laboratory or Abbe refractometers, inline process refractometers and finally Rayleigh Refractometers for measuring the refractive indices of gases. Refractometers are widely used in various disciplines such as mineralogy, medicine, veterinary, automotive industry…..etc., to examine products as diverse as gemstones, blood samples, auto coolants, industrial oils. The refractive index is an optical parameter to analyze liquid samples. It serves to identify or confirm the identity of a sample by comparing its refractive index to known values, helps assess the purity of a sample by comparing its refractive index to the value for the pure substance, helps determine the concentration of a solute in a solution by comparing the solution's refractive index to a standard curve. Let us go briefly over the types of refractometers: TRADITIONAL REFRACTOMETERS take advantage of the critical angle principle by which a shadow line is projected onto a small glass thru prisms and lenses. The specimen is placed between a small cover plate and a measuring prism. The point at which the shadow line crosses the scale indicates the reading. There is automatic temperature compensation, because the refractive index varies based on temperature. DIGITAL HANDHELD REFRACTOMETERS are compact, lightweight, water and high temperature resistant testing devices. Measurement times are very short and in the range of two to three seconds only. LABORATORY REFRACTOMETERS are ideal for users planning to measure multiple parameters and get the outputs in various formats, take printouts. Laboratory refractometers offer a wider range and higher accuracy than handheld refractometers. They can be connected to computers and controlled externally. INLINE PROCESS REFRACTOMETERS can be configured to constantly collect specified statistics of the material remotely. The microprocessor control provides computer power that makes these devices very versatile, time-saving and economical. Finally, the RAYLEIGH REFRACTOMETER is used for measuring the refractive indices of gases. Quality of light is very important in the workplace, factory floor, hospitals, clinics, schools, public buildings and many other places. LUX METERS are used to measure luminuous intensity (brightness). Special optic filters match the spectral sensitivity of the human eye. Luminous intensity is measured and reported in foot-candle or lux (lx). One lux is equal to one lumen per square meter and one foot-candle is equal to one lumen per square foot. Modern lux meters are equipped with internal memory or a data logger to record the measurements, cosine correction of the angle of incident light and software to analyze readings. There are lux meters for measuring UVA radiation. High end version lux meters offer Class A status to meet CIE, graphic displays, statistical analysis functions, large measurement range up to 300 klx, manual or automatic range selection, USB and other outputs. A LASER RANGEFINDER is a test instrument which uses a laser beam to determine the distance to an object. Most laser rangefinders operation is based on the time of flight principle. A laser pulse is sent in a narrow beam towards the object and the time taken by the pulse to be reflected off the target and returned to the sender is measured. This equipment is not suitable however for high precision sub-millimeter measurements. Some laser rangefinders use the Doppler effect technique to determine whether the object is moving towards or away from the rangefinder as well as the object’s speed. The precision of a laser rangefinder is determined by the rise or fall time of the laser pulse and the speed of the receiver. Rangefinders that use very sharp laser pulses and very fast detectors are capable to measure the distance of an object to within a few millimeters. Laser beams will eventually spread over long distances due to the divergence of the laser beam. Also distortions caused by air bubbles in the air make it difficult to get an accurate reading of the distance of an object over long distances of more than 1 km in open and unobscured terrain and over even shorter distances in humid and foggy places. High end military rangefinders operate at ranges up to 25 km and are combined with binoculars or monoculars and can be connected to computers wirelessly. Laser rangefinders are used in 3-D object recognition and modelling, and a wide variety of computer vision-related fields such as time-of-flight 3D scanners offering high-precision scanning abilities. The range data retrieved from multiple angles of a single object can be used to produce complete 3-D models with as little error as possible. Laser rangefinders used in computer vision applications offer depth resolutions of tenths of millimeters or less. Many other application areas for laser rangefinders exist, such as sports, construction, industry, warehouse management. Modern laser measurement tools include functions such as capability to make simple calculations, such as the area and volume of a room, switching between imperial and metric units. An ULTRASONIC DISTANCE METER works on a similar principle as a laser distance meter, but instead of light it uses sound with a pitch too high for the human ear to hear. The speed of sound is only about 1/3 of a km per second, so the time measurement is easier. Ultrasound has many of the same advantages of a Laser Distance Meter, namely a single person and one-handed operation. There is no need to access the target personally. However ultrasound distance meters are intrinsically less accurate, because sound is far more difficult to focus than laser light. Accuracy is typically several centimeters or even worse, while it is a few millimeters for laser distance meters. Ultrasound needs a large, smooth, flat surface as the target. This is a severe limitation. You can’t measure to a narrow pipe or similar smaller targets. The ultrasound signal spreads out in a cone from the meter and any objects in the way can interfere with the measurement. Even with laser aiming, one cannot be sure that the surface from which the sound reflection is detected is the same as that where the laser dot is showing. This can lead to errors. Range is limited to tens of meters, whereas laser distance meters can measure hundreds of meters. Despite all these limitations, ultrasonic distance meters cost much less. Handheld ULTRASONIC CABLE HEIGHT METER is a test instrument for measuring cable sag, cable height and overhead clearance to ground. It is the safest method for cable height measurement because it eliminates cable contact and the use of heavy fiberglass poles. Similar to other ultrasonic distance meters, the cable height meter is a one-man simple operation device that sends ultrasound waves to target, measures time to echo, calculates distance based on speed of sound and adjusts itself for air temperature. A SOUND LEVEL METER is a testing instrument that measures sound pressure level. Sound level meters are useful in noise pollution studies for the quantification of different kinds of noise. The measurement of noise pollution is important in construction, aerospace, and many other industries. The American National Standards Institute (ANSI) specifies sound level meters as three different types, namely 0, 1 and 2. The relevant ANSI standards set performance and accuracy tolerances according to three levels of precision: Type 0 is used in laboratories, Type 1 is used for precision measurements in the field, and Type 2 is used for general-purpose measurements. For compliance purposes, readings with an ANSI Type 2 sound level meter and dosimeter are considered to have an accuracy of ±2 dBA, whereas a Type 1 instrument has an accuracy of ±1 dBA. A Type 2 meter is the minimum requirement by OSHA for noise measurements, and is usually sufficient for general purpose noise surveys. The more accurate Type 1 meter is intended for the design of cost-effective noise controls. International industry standards related to frequency weighting, peak sound pressure levels….etc are beyond the scope here due to the details associated with them . Before purchasing a particular sound level meter, we advise that you make sure to know what standards compliance your workplace requires and make the right decision in purchasing a particular model of test instrument. ENVIRONMENTAL ANALYZERS like TEMPERATURE & HUMIDITY CYCLING CHAMBERS, ENVIRONMENTAL TESTING CHAMBERS come in a variety of sizes, configurations and functions depending on the area of application, the specific industrial standards compliance needed and the end users needs. They can be configured and manufactured according to custom requirements. There is a broad range of test specifications such as MIL-STD, SAE, ASTM to help determine the most appropriate temperature humidity profile for your product. Temperature / humidity testing is generally carried out for : Accelerated Aging: Estimates the life of a product when actual lifespan is unknown under normal use. Accelerated aging exposes the product to high levels of controlled temperature, humidity, and pressure within a relatively shorter timeframe than the expected lifespan of the product. Instead of waiting long times and years to see product lifespan, one can determine it using these tests within a much shorter and reasonable time using these chambers. Accelerated Weathering: Simulates exposure from moisture, dew, heat, UV….etc. Weathering and UV exposure causes damage to coatings, plastics, inks, organic materials, devices…etc. Fading, yellowing, cracking, peeling, brittleness, loss of tensile strength, and delamination occur under prolonged UV exposure. Accelerated weathering tests are designed to determine if products will stand the test of time. Heat Soak/Exposure Thermal Shock: Aimed to determine the ability of materials, parts and components to withstand sudden changes in temperature. Thermal shock chambers rapidly cycle products between hot and cold temperature zones to see the effect of multiple thermal expansions and contractions as would be the case in nature or industrial environments throughout the many seasons and years.

- Ultrasonic Machining, Ultrasonic Impact Grinding, Custom Manufacturing
Ultrasonic Machining, Ultrasonic Impact Grinding, Rotary Ultrasonic Machining, Non-Conventional Machining, Custom Manufacturing - AGS-TECH Inc. New Mexico, USA Ultrasonic Machining & Rotary Ultrasonic Machining & Ultrasonic Impact Grinding Another popular NON-CONVENTIONAL MACHINING technique we frequently use is ULTRASONIC MACHINING (UM), also widely known as ULTRASONIC IMPACT GRINDING, where material is removed from a workpiece surface by microchipping and erosion with abrasive particles using a vibrating tool oscillating at ultrasonic frequencies, aided by an abrasive slurry that flows freely between the workpiece and the tool. It differs from most other conventional machining operations because very little heat is produced. The tip of the ultrasonic machining tool is called a “sonotrode” which vibrates at amplitudes of 0.05 to 0.125 mm and frequencies around 20 kHz. The vibrations of the tip transmit high velocities to fine abrasive grains between the tool and the surface of the workpiece. The tool never contacts the workpiece and therefore the grinding pressure is rarely more than 2 pounds. This working principle makes this operation perfect for machining extremely hard and brittle materials, such as glass, sapphire, ruby, diamond, and ceramics. The abrasive grains are located within a water slurry with a concentration between 20 to 60% by volume. The slurry also acts as the carrier of the debris away from the cutting / machining region. We use as abrasive grains mostly boron carbide, aluminum oxide and silicon carbide with grain sizes ranging from 100 for roughing processes to 1000 for our finishing processes. The ultrasonic-machining (UM) technique is best suited for hard and brittle materials like ceramics and glass, carbides, precious stones, hardened steels. The surface finish of ultrasonic machining depends upon the hardness of the workpiece/tool and the average diameter of the abrasive grains used. The tool tip is generally a low-carbon steel, nickel and soft steels attached to a transducer through the toolholder. The ultrasonic-machining process utilizes the plastic deformation of metal for the tool and the brittleness of the workpiece. The tool vibrates and pushes down on the abrasive slurry containing grains until the grains impact the brittle workpiece. During this operation, the workpiece is broken down while the tool bends very slightly. Using fine abrasives, we can achieve dimensional tolerances of 0.0125 mm and even better with ultrasonic-machining (UM). Machining time depends upon the frequency at which the tool is vibrating, the grain size and hardness, and the viscosity of the slurry fluid. The less viscous the slurry fluid, the faster it can carry away used abrasive. Grain size must be equal or greater than the hardness of the workpiece. As an example we can machine multiple aligned holes 0.4 mm in diameter on a 1.2 mm wide glass strip with ultrasonic machining. Let us get a little bit into the physics of the ultrasonic machining process. Microchipping in ultrasonic machining is possible thanks to the high stresses produced by particles striking the solid surface. Contact times between particles and surfaces are very short and in the order of 10 to 100 microseconds. The contact time can be expressed as: to = 5r/Co x (Co/v) exp 1/5 Here r is the radius of the spherical particle, Co is the elastic wave velocity in the workpiece (Co = sqroot E/d) and v is the velocity that the particle hits the surface with. The force a particle exerts on the surface is obtained from the rate of change of momentum: F = d(mv)/dt Here m is the grain mass. The average force of the particles (grains) hitting and rebounding from the surface is: Favg = 2mv / to Here to is the contact time. When numbers are plugged into this expression, we see that even though the parts are very small, since the contact area is also very small, the forces and thus the stresses exerted are significantly high to cause microchipping and erosion. ROTARY ULTRASONIC MACHINING (RUM): This method is a variation of ultrasonic machining, where we replace the abrasive slurry with a tool that has metal-bonded diamond abrasives that have been either impregnated or electroplated on the tool surface. The tool is rotated and ultrasonically vibrated. We press the workpiece at constant pressure against the rotating and vibrating tool. The rotary ultrasonic machining process gives us capabilities such as producing deep holes in hard materials at high material removal rates. Since we deploy a number of conventional and non-conventional manufacturing techniques, we can be of help to you whenever you have questions about a particular product and the fastest and most economical way of manufacturing & fabricating it.

- Keys Splines and Pins, Square Flat Key, Pratt and Whitney, Woodruff...
Keys Splines and Pins, Square Flat Key, Pratt and Whitney, Woodruff, Crowned Involute Ball Spline Manufacturing, Serrations, Gib-Head Key from AGS-TECH Inc. Keys & Splines & Pins Manufacturing Other miscellaneous fasteners we provide are keys, splines, pins, serrations. KEYS: A key is a piece of steel lying partly in a groove in the shaft and extending into another groove in the hub. A key is used to secure gears, pulleys, cranks, handles, and similar machine parts to shafts, so that the motion of the part is transmitted to the shaft, or the motion of the shaft to the part, without slippage. The key may also act in a safety capacity; its size can be calculated so that when overloading takes place, the key will shear or break before the part or shaft breaks or deforms. Our keys are also available with a taper on their top surfaces. For tapered keys, the keyway in the hub is tapered to accommodate the taper on the key. Some major types of keys we offer are: Square key Flat key Gib-Head Key – These keys are the same as flat or square tapered keys but with added head for ease of removal. Pratt and Whitney Key – These are rectangular keys with rounded edges. Two-thirds of these keys sit in the shaft and one-third in the hub. Woodruff Key – These keys are semicircular and fit into semicircular keyseats in the shafts and rectangular keyways in the hub. SPLINES: Splines are ridges or teeth on a drive shaft that mesh with grooves in a mating piece and transfer torque to it, maintaining the angular correspondence between them. Splines are capable of carrying heavier loads than keys, permit lateral movement of a part, parallel to the axis of the shaft, while maintaining positive rotation, and allow the attached part to be indexed or changed to another angular position. Some splines have straight-sided teeth, whereas others have curved-sided teeth. Splines with curved-sided teeth are called involute splines. Involute splines have pressure angles of 30, 37.5 or 45 degrees. Both internal and external spline versions are available. SERRATIONS are shallow involute splines with 45 degree pressure angles and are used for holding parts like plastic knobs. Major types of splines we offer are: Parallel key splines Straight-side splines – Also called parallel-side splines, they are used in many automotive and machine industry applications. Involute splines – These splines are similar in shape to involute gears but have pressure angles of 30, 37.5 or 45 degrees. Crowned splines Serrations Helical splines Ball splines PINS / PIN FASTENERS: Pin fasteners are an inexpensive and effective method of assembly when loading is primarily in shear. Pin fasteners can be separated into two groups: Semipermanent Pinsand Quick-Release Pins. Semipermanent pin fasteners require application of pressure or the aid of tools for installation or removal. Two basic types are Machine Pins and Radial Locking Pins. We offer the following machine pins: Hardened and ground dowel pins – We have standardized nominal diameters between 3 to 22 mm available and can machine custom sized dowel pins. Dowel pins can be used to hold laminated sections together, they can fasten machine parts with high alignment accuracy, lock components on shafts. Taper pins – Standard pins with 1:48 taper on the diameter. Taper pins are suitable for light-duty service of wheels and levers to shafts. Clevis pins - We have standardized nominal diameters between 5 to 25 mm available and can machine custom sized clevis pins. Clevis pins can be used on mating yokes, forks and eye members in knuckle joints. Cotter pins – Standardized nominal diameters of cotter pins range from 1 to 20 mm. Cotter pins are locking devices for other fasteners and are generally used with a castle or slotted nuts on bolts, screws, or studs. Cotter pins enable low-cost and convenient locknut assemblies. Two basic pin forms are offered as Radial Locking Pins, solid pins with grooved surfaces and hollow spring pins which are either slotted or come with spiral-wrapped configuration. We offer the following radial locking pins: Grooved straight pins – Locking is enabled by parallel, longitudinal grooves uniformly spaced around the pin surface. Hollow spring pins – These pins are compressed when driven into holes and pins exert spring pressure against the hole walls along their entire engaged length to produce locking fits Quick-release pins: Available types vary widely in head styles, types of locking and release mechanisms, and range of pin lengths. Quick-release pins have applications such as clevis-shackle pin, draw-bar hitch pin, rigid coupling pin, tubing lock pin, adjustment pin, swivel hinge pin. Our quick release pins can be grouped into one of two basic types: Push-pull pins – These pins are made with either a solid or hollow shank containing a detent assembly in the form of a locking lug, button or ball, backed up by some sort of plug, spring or resilient core. The detent member projects from the pins surface until sufficient force is applied in assembly or removal to overcome the spring action and to release the pins. Positive-locking pins - For some quick-release pins, the locking action is independent of insertion and removal forces. Positive-locking pins are suited for shear-load applications as well as for moderate tension loads. CLICK Product Finder-Locator Service RÛPERA BERÊ
- Laser Machining, LM, Laser Cutting, CO2 Laser Processing, Nd-YAG Cut
Laser Machining - LM - Laser Cutting - Custom Parts Manufacturing - CO2 Laser Processing - Nd-YAG - Cutting - Boring Laser Machining & Cutting & LBM LASER CUTTING is a HIGH-ENERGY-BEAM MANUFACTURING technology that uses a laser to cut materials, and is typically used for industrial manufacturing applications. In LASER BEAM MACHINING (LBM), a laser source focuses optical energy on the surface of the workpiece. Laser cutting directs the highly focused and high-density output of a high-power laser, by computer, at the material to be cut. The targeted material then either melts, burns, vaporizes away, or is blown away by a jet of gas, in a controlled manner leaving an edge with a high-quality surface finish. Our industrial laser cutters are suitable for cutting flat-sheet material as well as structural and piping materials, metallic and nonmetallic workpieces. Generally no vacuum is required in the laser beam machining and cutting processes. There are several types of lasers used in laser cutting and manufacturing. The pulsed or continuous wave CO2 LASER is suited for cutting, boring, and engraving. The NEODYMIUM (Nd) and neodymium yttrium-aluminum-garnet (Nd-YAG) LASERS are identical in style and differ only in application. The neodymium Nd is used for boring and where high energy but low repetition is required. The Nd-YAG laser on the other hand is used where very high power is required and for boring and engraving. Both CO2 and Nd/ Nd-YAG lasers can be used for LASER WELDING. Other lasers we use in manufacturing include Nd:GLASS, RUBY and EXCIMER. In Laser Beam Machining (LBM), the following parameters are important: The reflectivity and thermal conductivity of the workpiece surface and its specific heat and latent heat of melting and evaporation. The efficiency of the Laser Beam Machining (LBM) process increases with decreasing of these parameters. The cutting depth can be expressed as: t ~ P / (v x d) This means, the cutting depth “t” is proportional to the power input P and inversely proportional to cutting speed v and laser-beam spot diameter d. The surface produced with LBM is generally rough and has a heat-affected zone. CARBONDIOXIDE (CO2) LASER CUTTING and MACHINING: The DC-excited CO2 lasers get pumped by passing a current through the gas mix whereas the RF-excited CO2 lasers use radio frequency energy for excitation. The RF method is relatively new and has become more popular. DC designs require electrodes inside the cavity, and therefore they can have electrode erosion and plating of electrode material on the optics. To the contrary, RF resonators have external electrodes and therefore they are not prone to those problems. We use CO2 lasers in industrial cutting of many materials such as mild steel, aluminum, stainless steel, titanium and plastics. YAG LASER CUTTING and MACHINING: We use YAG lasers for cutting and scribing metals and ceramics. The laser generator and external optics require cooling. Waste heat is generated and transferred by a coolant or directly to air. Water is a common coolant, usually circulated through a chiller or heat transfer system. EXCIMER LASER CUTTING and MACHINING: An excimer laser is a kind of laser with wavelengths in the ultraviolet region. The exact wavelength depends on the molecules used. For example the following wavelengths are associated with the molecules shown in parantheses: 193 nm (ArF), 248 nm (KrF), 308 nm (XeCl), 353 nm (XeF). Some excimer lasers are tunable. Excimer lasers have the attractive property that they can remove very fine layers of surface material with almost no heating or change to the remainder of the material. Therefore excimer lasers are well suited to precision micromachining of organic materials such as some polymers and plastics. GAS-ASSISTED LASER CUTTING: Sometimes we use laser beams in combination with a gas stream, like oxygen, nitrogen or argon for cutting thin sheet materials. This is done using a LASER-BEAM TORCH. For stainless steel and aluminum we use high-pressure inert-gas-assisted laser cutting using nitrogen. This results in oxide-free edges to improve weldability. These gas streams also blow away molten and vaporized material from workpiece surfaces. In a LASER MICROJET CUTTING we have a water-jet guided laser in which a pulsed laser beam is coupled into a low-pressure water jet. We use it to perform laser cutting while using the water jet to guide the laser beam, similar to an optical fiber. The advantages of laser microjet are that the water also removes debris and cools the material, it is faster than traditional ''dry'' laser cutting with higher dicing speeds, parallel kerf and omnidirectional cutting capability. We deploy different methods in cutting using lasers. Some of the methods are vaporization, melt and blow, melt blow and burn, thermal stress cracking, scribing, cold cutting and burning, stabilized laser cutting. - Vaporization cutting: The focused beam heats the surface of the material to its boiling point and creates a hole. The hole leads to a sudden increase in absorptivity and quickly deepens the hole. As the hole deepens and the material boils, the generated vapor erodes the molten walls blowing material out and further enlarging the hole. Non melting material such as wood, carbon and thermoset plastics are usually cut by this method. - Melt and blow cutting: We use high-pressure gas to blow molten material from the cutting area, decreasing the required power. The material is heated to its melting point and then a gas jet blows the molten material out of the kerf. This eliminates the need to raise the temperature of the material any further. We cut metals with this technique. - Thermal stress cracking: Brittle materials are sensitive to thermal fracture. A beam is focused on the surface causing localized heating and thermal expansion. This results in a crack that can then be guided by moving the beam. We use this technique in glass cutting. - Stealth dicing of silicon wafers: The separation of microelectronic chips from silicon wafers is performed by the stealth dicing process, using a pulsed Nd:YAG laser, the wavelength of 1064 nm is well adopted to the electronic band gap of silicon (1.11 eV or 1117 nm). This is popular in semiconductor device fabrication. - Reactive cutting: Also called flame cutting, this technique can be resembled to oxygen torch cutting but with a laser beam as the ignition source. We use this for cutting carbon steel in thicknesses over 1 mm and even very thick steel plates with little laser power. PULSED LASERS provide us a high-power burst of energy for a short period and are very effective in some laser cutting processes, such as piercing, or when very small holes or very low cutting speeds are required. If a constant laser beam was used instead, the heat could reach the point of melting the entire piece being machined. Our lasers have the ability to pulse or cut CW (Continuous Wave) under NC (numerical control) program control. We use DOUBLE PULSE LASERS emitting a series of pulse pairs to improve material removal rate and hole quality. The first pulse removes material from the surface and the second pulse prevents the ejected material from readhering to the side of the hole or cut. Tolerances and surface finish in laser cutting and machining are outstanding. Our modern laser cutters have positioning accuracies in the neighborhood of 10 micrometers and repeatabilities of 5 micrometers. Standard roughnesses Rz increase with the sheet thickness, but decreases with laser power and cutting speed. The laser cutting and machining processes are capable of achieving close tolerances, often to within 0.001 inch (0.025 mm) Part geometry and the mechanical features of our machines are optimized to achieve best tolerance capabilities. Surface finishes we can obtain from laser beam cutting may range between 0.003 mm to 0.006 mm. Generally we easily achieve holes with 0.025 mm diameter, and holes as small as 0.005 mm and hole depth-to-diameter ratios of 50 to 1 have been produced in various materials. Our simplest and most standard laser cutters will cut carbon steel metal from 0.020–0.5 inch (0.51–13 mm) in thickness and can easily be up to thirty times faster than standard sawing. Laser-beam machining is used widely for drilling and cutting of metals, nonmetals and composite materials. Advantages of laser cutting over mechanical cutting include easier workholding, cleanliness and reduced contamination of the workpiece (since there is no cutting edge as in traditional milling or turning which can become contaminated by the material or contaminate the material, i.e. bue build-up). The abrasive nature of composite materials may make them difficult to machine by conventional methods but easy by laser machining. Because the laser beam does not wear during the process, precision obtained may be better. Because laser systems have a small heat-affected zone, there is also a lesser chance of warping the material that is being cut. For some materials laser cutting can be the only option. Laser-beam cutting processes are flexible, and fiber optic beam delivery, simple fixturing, short set-up times, availability of three dimensional CNC systems make it possible for laser cutting and machining to compete successfully with other sheet metal fabrication processes such as punching. This being said, laser technology can sometimes be combined with the mechanical fabrication technologies for improved overall efficiency. Laser cutting of sheet metals has the advantages over plasma cutting of being more precise and using less energy, however, most industrial lasers cannot cut through the greater metal thickness that plasma can. Lasers operating at higher powers such as 6000 Watts are approaching plasma machines in their ability to cut through thick materials. However the capital cost of these 6000 Watt laser cutters is much higher than that of plasma cutting machines capable of cutting thick materials like steel plate. There are also disadvantages of laser cutting and machining. Laser cutting involves high power consumption. Industrial laser efficiencies may range from 5% to 15%. The power consumption and efficiency of any particular laser will vary depending on output power and operating parameters. This will depend on type of laser and how well the laser matches the work at hand. Amount of laser cutting power required for a particular task depends on the material type, thickness, process (reactive/inert) used and the desired cutting rate. The maximum production rate in laser cutting and machining is limited by a number of factors including laser power, process type (whether reactive or inert), material properties and thickness. In LASER ABLATION we remove material from a solid surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates. At high laser flux, the material is typically converted to a plasma. High power lasers clean a large spot with a single pulse. Lower power lasers use many small pulses which may be scanned across an area. In laser ablation we remove material with a pulsed laser or with a continuous wave laser beam if the laser intensity is high enough. Pulsed lasers can drill extremely small, deep holes through very hard materials. Very short laser pulses remove material so quickly that the surrounding material absorbs very little heat, therefore laser drilling can be done on delicate or heat-sensitive materials. Laser energy can be selectively absorbed by coatings, therefore CO2 and Nd:YAG pulsed lasers can be used to clean surfaces, remove paint and coating, or prepare surfaces for painting without damaging the underlying surface. We use LASER ENGRAVING and LASER MARKING to engrave or mark an object. These two techniques are in fact the most widely used applications. No inks are used, nor does it involve tool bits which contact the engraved surface and wear out which is the case with traditional mechanical engraving and marking methods. Materials specially designed for laser engraving and marking include laser-sensitive polymers and special new metal alloys. Although laser marking and engraving equipment is relatively more expensive compared to alternatives such as punches, pins, styli, etching stamps….etc., they have become more popular due to their accuracy, reproducibility, flexibility, ease of automation and on-line application in a wide variety of manufacturing environments. Finally, we use laser beams for several other manufacturing operations: - LASER WELDING - LASER HEAT TREATING: Small-scale heat treating of metals and ceramics to modify their surface mechanical and tribological properties. - LASER SURFACE TREATMENT / MODIFICATION: Lasers are used to clean surfaces, introduce functional groups, modify surfaces in an effort to improve adhesion prior to coating deposition or joining processes.

Adhesive Bonding - Adhesives - Sealing - Fastening - Joining Nonmetallic Materials - Optical Contacting - UV Bonding - Specialty Glue - Epoxy - Custom Assembly Adhesive Bonding & Sealing & Fastening Mechanical Custom and Assembly Among our other most valuable JOINING techniques are ADHESIVE BONDING, MECHANICAL FASTENING and ASSEMBLY, JOINING NONMETALLIC MATERIALS. We dedicate this section to these joining and assembly techniques because of their importance in our manufacturing operations and the extensive content related to them. ADHESIVE BONDING: Did you know that there are specialized epoxies that can be used for almost hermetic level sealing ? Depending on the level of sealing you require, we will choose or formulate a sealant for you. Also do you know that some sealants can be heat cured whereas others require only a UV light to be cured ? If you explain us your application, we can formulate the right epoxy for you. You may require something that is bubble free or something that matches the thermal coefficient of expansion of your mating parts. We have it all ! Contact us and explain your application. We will then choose the most suitable material for you or custom formulate a solution for your challenge. Our materials come with inspection reports, material data sheets and certification. We are capable to assemble your components very economically and ship you completed and quality inspected products. Adhesives are available to us in various forms such as liquids, solutions, pastes, emulsions, powder, tape and films. We use three basic types of adhesives for our joining processes: -Natural Adhesives -Inorganic Adhesives -Synthetic Organic Adhesives For load-bearing applications in manufacturing and fabrication we use adhesives with high cohesive strength, and they are mostly synthetic organic adhesives, which may be thermoplastics or thermosetting polymers. Synthetic organic adhesives are our most important category and can be classified as: Chemically Reactive Adhesives: Popular examples are silicones, polyurethanes, epoxies, phenolics, polyimides, anaerobics like Loctite. Pressure Sensitive Adhesives: Common examples are natural rubber, nitrile rubber, polyacrylates, butyl rubber. Hot Melt Adhesives: Examples are thermoplastics like ethylene-vinyl-acetate copolymers, polyamides, polyester, polyolefins. Reactive Hot Melt Adhesives: They have a thermoset portion based on urethane’s chemistry. Evaporative / Diffusion Adhesives: Popular ones are vinyls, acrylics, phenolics, polyurethanes, synthetic and natural rubbers. Film and Tape Type Adhesives: Examples are nylon-epoxies, elastomer-epoxies, nitrile-phenolics, polyimides. Delayed Tack Adhesives: These include polyvinyl acetates, polystyrenes, polyamides. Electrically and Thermally Conductive Adhesives: Popular examples are epoxies, polyurethanes, silicones, polyimides. According to their chemistries adhesives we use in manufacturing can be classified as: - Epoxy based adhesive systems: High strength and high temperature endurance as high as 473 Kelvin are characteristic of these. Bonding agents in sand mold castings are this type. - Acrylics: These are suitable for applications that involve contaminated dirty surfaces. - Anaerobic adhesive systems: Curing by oxygen deprivation. Hard and brittle bonds. - Cyanoacrylate: Thin bond lines with setting times under 1 minute. - Urethanes: We use them as popular sealants with high toughness and flexibility. - Silicones: Well known for their resistance against moisture and solvents, high impact and peel strength. Relatively long curing times of up to a few days. To optimize the properties in adhesive bonding, we may combine several adhesives. Examples are epoxy-silicon, nitrile-phenolic combined adhesive systems. Polyimides and polybenzimidazoles are used in high-temperature applications. Adhesive joints withstand shear, compressive, and tensile forces pretty well but they may easily fail when subjected to peeling forces. Therefore, in adhesive bonding, we must consider the application and design the joint accordingly. Surface preparation is also of critical importance in adhesive bonding. We clean, treat and modify surfaces to increase the strength and reliability of interfaces in adhesive bonding. Using special primers, wet and dry etching techniques such as plasma cleaning are among our common methods. An adhesion promoting layer such as a thin oxide may improve adhesion in some applications. Increasing surface roughness may also be beneficial prior to adhesive bonding but needs to be well controlled and not exaggerated because excessive roughness can result in trapping of air and therefore a weaker adhesively bonded interface. We use nondestructive methods for testing the quality and strength of our products after adhesive bonding operations. Our techniques include methods such as acoustic impact, IR detection, ultrasonic testing. Advantages of adhesive bonding are: -Adhesive bonding can provide structural strength, sealing and insulation function, suppression of vibration and noise. -Adhesive bonding can eliminate localized stresses at the interface by eliminating the need for joining using fasteners or welding. -Generally no holes are needed for adhesive bonding, and therefore external appearance of components is unaffected. -Thin and fragile parts can be adhesively joined without damage and without significant increase in weight. -Adhesive joining can be used to bond parts made of very different materials with significantly different sizes. -Adhesive bonding can be used on heat sensitive components safely due to low temperatures involved. However some disadvantages do exist for adhesive bonding and our customers should consider these prior to finalizing their designs of joints: -Service temperatures are relatively low for adhesively joint components -Adhesive bonding may require long bonding and curing times. -Surface preparation is needed in adhesive bonding. -Especially for large structures it may be difficult to test adhesively bonded joints nondestructively. -Adhesive bonding may pose reliability concerns in the long term due to degradation, stress corrosion, dissolution….and the like. One of our outstanding products is ELECTRICALLY CONDUCTIVE ADHESIVE, which can replace lead-based solders. Fillers such as silver, aluminum, copper, gold make these pastes conductive. Fillers can be in the form of flakes, particles or polymeric particles coated with thin films of silver or gold. Fillers can also improve thermal conductivity besides electrical. Let us continue with our other joining processes used in manufacturing products. MECHANICAL FASTENING and ASSEMBLY: Mechanical fastening offers us ease of manufacturing, ease of assembly and disassembly, ease of transportation, ease of parts replacement, maintenance and repair, ease in design of movable and adjustable products, lower cost. For fastening we use: Threaded Fasteners: Bolts, screws and nuts are examples of these. Depending on your application, we can provide you specially designed nuts and lock washers for dampening vibration. Riveting: Rivets are among our most common methods of permanent mechanical joining and assembly processes. Rivets are placed in holes and their ends are deformed by upsetting. We perform assembly using riveting at room temperature as well as at high temperatures. Stitching / Stapling / Clinching: These assembly operations are widely used in manufacturing and are basically the same as is used on papers and cardboards. Both metallic and nonmetallic materials can be joined and assembled quickly without need to predrill holes. Seaming: An inexpensive fast joining technique we use widely in manufacturing of containers and metal cans. It is based on folding two thin pieces of material together. Even airtight and watertight seams are possible, especially if seaming is performed jointly with using sealants and adhesives. Crimping: Crimping is a joining method where we do not use fasteners. Electrical or fiber optic connectors are sometimes installed using crimping. In high volume manufacturing, crimping is an indispensible technique for fast joining and assembly of both flat and tubular components. Snap-in Fasteners: Snap fits are also an economical joining technique in assembly and manufacturing. They permit quick assembly and disassembly of components and are a good fit for household products, toys, furniture among others. Shrink and Press Fits: Another mechanical assembly technique, namely shrink fitting is based on the principle of differential thermal expansion and contraction of two components, whereas in press fitting one component is forced over another resulting in good joint strength. We use shrink fitting widely in the assembly and manufacturing of cable harness, and mounting gears and cams on shafts. JOINING NONMETALLIC MATERIALS: Thermoplastics can be heated and melted at the interfaces to be joined and by applying pressure adhesive joining can be accomplished by fusion. Alternatively thermoplastic fillers of the same type may be used for the joining process. Joining of some polymers such as polyethylene may be difficult due to oxidation. In such cases, an inert shielding gas like nitrogen may be used against oxidation. Both external as well as internal heat sources can be used in adhesive joining of polymers. Examples of external sources we commonly use in adhesive joining of thermoplastics are hot air or gases, IR radiation, heated tools, lasers, resistive electrical heating elements. Some of our internal heat sources are ultrasonic welding and friction welding. In some assembly and manufacturing applications we use adhesives for bonding polymers. Some polymers such as PTFE (Teflon) or PE (Polyethylene) have low surface energies and therefore a primer is first applied prior to completing the adhesive bonding process with a suitable adhesive. Another popular technique in joining is the “Clearweld Process” where a toner is first applied to the polymer interfaces. A laser is then directed at the interface, but it does not heat the polymer, but does heat the toner. This makes it possible to heat only well-defined interfaces resulting in localized welds. Other alternative joining techniques in the assembly of thermoplastics are using fasteners, self-tapping screws, integrated snap-fasteners. An exotic technique in manufacturing and assembly operations is embedding tiny micron-sized particles into the polymer and using high-frequency electromagnetic field to inductively heat and melt it at the interfaces to be joined. Thermoset materials on the other hand, do not soften or melt with increasing temperatures. Therefore, adhesive joining of thermoset plastics are usually carried out using threaded or other molded-in inserts, mechanical fasteners and solvent bonding. Regarding joining and assembly operations involving glass and ceramics in our manufacturing plants, here are a few common observations: In cases where a ceramic or glass have to be joined with difficult-to-bond materials, the ceramic or glass materials are frequently coated with a metal that bonds itself easily to them, and then joined to the difficult-to-bond material. When ceramic or glass has a thin metal coating it can be more readily brazed to metals. Ceramics are sometimes joined and assembled together during their shaping process while still hot, soft and tacky. Carbides can be more easily brazed to metals if they have as their matrix material a metal binder such as cobalt or nickel-molybdenum alloy. We braze carbide cutting tools to steel toolholders. Glasses bond well to each other and metals when hot and soft.

SADT-SINOAGE Brand Metrology and Test Equipment catalog download. In this catalog you will find some of these instruments for the evaluation of surfaces and coatings. Some of the instruments and techniques used for such purposes are: COATING THICKNESS METER : Different types of coatings require different types of coating testers. A basic understanding of the various techniques is thus essential for the user to choose the right equipment. In the Magnetic Induction Method of coating thickness measurement we measure nonmagnetic coatings over ferrous substrates and magnetic coatings over nonmagnetic substrates. The probe is positioned on the sample and the linear distance between the probe tip that contacts the surface and the base substrate is measured. Inside the measurement probe is a coil that generates a changing magnetic field. When the probe is placed on the sample, the magnetic flux density of this field is altered by the thickness of a magnetic coating or the presence of a magnetic substrate. The change in magnetic inductance is measured by a secondary coil on the probe. The output of the secondary coil is transferred to a microprocessor, where it’s shown as a coating thickness measurement on the digital display. This quick test is suitable for liquid or powder coatings, platings such as chrome, zinc, cadmium or phosphate over steel or iron substrates. Coatings such as paint or powder thicker than 0.1 mm are suitable for this method. The magnetic induction method is not well suited for nickel over steel coatings because of nickel’s partial magnetic property. Phase-sensitive Eddy current method is more suitable for these coatings. Another type of coating where the magnetic induction method is prone to failure is zinc galvanized steel. The probe will read a thickness equal to the total thickness. Newer model instruments are capable of self-calibration by detecting the substrate material through the coating. This is of course very helpful when a bare substrate is not available or when the substrate material is unknown. Cheaper equipment versions require however calibration of the instrument on a bare and uncoated substrate. The Eddy Current Method of coating thickness measurement measures nonconductive coatings on nonferrous conductive substrates, nonferrous conductive coatings on nonconductive substrates and some nonferrous metal coatings on nonferrous metals. It is similar to the magnetic inductive method previously mentioned containing a coil and similar probes. The coil in the Eddy current method has the dual function of excitation and measurement. This probe coil is driven by a high-frequency oscillator to generate an alternating high-frequency field. When placed near a metallic conductor, eddy currents are generated in the conductor. Impedance change takes place in the probe coil. The distance between the probe coil and the conductive substrate material determines the amount of impedance change, which can be measured, correlated to a coating thickness and displayed in the form of a digital reading. Applications include liquid or powder coating on aluminum and nonmagnetic stainless steel, and anodize over aluminum. This method’s reliability depends on the part’s geometry and the coating’s thickness. The substrate needs to be known prior to taking readings. Eddy current probes shouldn’t be used for measuring nonmagnetic coatings over magnetic substrates such as steel and nickel over aluminum substrates. If users must measure coatings over magnetic or nonferrous conductive substrates they will be best served with a dual magnetic induction/Eddy current gage that automatically recognizes the substrate. A third method, called the Coulometric method of coating thickness measurement, is a destructive testing method that has many important functions. Measuring the duplex nickel coatings in the automotive industry is one of it major applications. In the coulometric method, the weight of an area of known size on a metallic coating is determined through localized anodic stripping of the coating. The mass-per-unit area of the coating thickness is then calculated. This measurement on the coating is made using an electrolysis cell, which is filled with an electrolyte specifically selected to strip the particular coating. A constant current runs through the test cell, and since the coating material serves as the anode, it gets deplated. The current density and the surface area are constant, and thus the coating thickness is proportional to the time it takes to strip and take off the coating. This method is very useful for measuring electrically conductive coatings on a conductive substrate. The Coulometric method can also be used for determining the coating thickness of multiple layers on a sample. For example, the thickness of nickel and copper can be measured on a part with a top coating of nickel and an intermediate copper coating on a steel substrate. Another example of a multilayer coating is chrome over nickel over copper on top of a plastic substrate. Coulometric test method is popular in electroplating plants with a small number of random samples. Yet a fourth method is the Beta Backscatter Method for measuring coating thicknesses. A beta-emitting isotope irradiates a test sample with beta particles. A beam of beta particles is directed through an aperture onto the coated component, and a proportion of these particles are backscattered as expected from the coating through the aperture to penetrate the thin window of a Geiger Muller tube. The gas in the Geiger Muller tube ionizes, causing a momentary discharge across the tube electrodes. The discharge which is in the form of a pulse is counted and translated to a coating thickness. Materials with high atomic numbers backscatter the beta particles more. For a sample with copper as a substrate and a gold coating of 40 microns thick, the beta particles are scattered by both the substrate and the coating material. If the gold coating thickness increases, the backscatter rate also increases. The change in the rate of particles scattered is therefore a measure of the coating thickness. Applications that are suitable for the beta backscatter method are those where the atomic number of the coating and substrate differ by 20 percent. These include gold, silver or tin on electronic components, coatings on machine tools, decorative platings on plumbing fixtures, vapor-deposited coatings on electronic components, ceramics and glass, organic coatings such as oil or lubricant over metals. The beta backscatter method is useful for thicker coatings and for substrate & coating combinations where magnetic induction or Eddy current methods won’t work. Changes in alloys affect the beta backscatter method, and different isotopes and multiple calibrations might be required to compensate. An example would be tin/lead over copper, or tin over phosphorous/bronze well known in printed circuit boards and contact pins, and in these cases the changes in alloys would be better measured with the more expensive X-ray fluorescence method. The X-ray fluorescence method for measuring coating thickness is a noncontact method that allows the measurement of very thin multilayer alloy coatings on small and complex parts. Parts are exposed to X-radiation. A collimator focuses the X-rays onto an exactly defined area of the test specimen. This X-radiation causes characteristic X-ray emission (i.e., fluorescence) from both the coating and the substrate materials of the test specimen. This characteristic X-ray emission is detected with an energy dispersive detector. Using the appropriate electronics, it’s possible to register only the X-ray emission from the coating material or substrate. It’s also possible to selectively detect a specific coating when intermediate layers are present. This technique is widely used on printed circuit boards, jewelry and optical components. The X-ray fluorescence is not suitable for organic coatings. The measured coating’s thickness should not exceed 0.5-0.8 mils. However, unlike the beta backscatter method, X-ray fluorescence can measure coatings with similar atomic numbers (for example nickel over copper). As previously mentioned, different alloys affect an instrument’s calibration. Analyzing base material and coating’s thickness are critical for ensuring precision readings. Todays systems and software programs reduce the need for multiple calibrations without sacrificing quality. Finally it is worth mentioning that there are gages that can operate in several of the above mentioned modes. Some have detachable probes for flexibility in use. Many of these modern instruments do offer statistical analysis capabilities for process control and minimal calibration requirements even if used on differently shaped surfaces or different materials. SURFACE ROUGHNESS TESTERS : Surface roughness is quantified by the deviations in the direction of the normal vector of a surface from its ideal form. If these deviations are large, the surface is considered rough; if they are small, the surface is considered smooth. Commercially available instruments called SURFACE PROFILOMETERS are used to measure and record surface roughness. One of the commonly used instruments features a diamond stylus traveling along a straight line over the surface. The recording instruments are able to compensate for any surface waviness and indicate only roughness. Surface roughness can be observed through a.) Interferometry and b.) Optical microscopy, scanning-electron microscopy, laser or atomic-force microscopy (AFM). Microscopy techniques are especially useful for imaging very smooth surfaces for which features cannot be captured by less sensitive instruments. Stereoscopic photographs are useful for 3D views of surfaces and can be used to measure surface roughness. 3D surface measurements can be performed by three methods. Light from an optical-interference microscope shines against a reflective surface and records the interference fringes resulting from the incident and reflected waves. Laser profilometers are used to measure surfaces through either interferometric techniques or by moving an objective lens to maintain a constant focal length over a surface. The motion of the lens is then a measure of the surface. Lastly, the third method, namely the atomic-force microscope, is used for measuring extremely smooth surfaces on the atomic scale. In other words with this equipment even atoms on the surface can be distinguished. This sophisticated and relatively expensive equipment scans areas of less than 100 micron square on specimen surfaces. GLOSS METERS, COLOR READERS, COLOR DIFFERENCE METER : A GLOSSMETERmeasures the specular reflection gloss of a surface. A measure of gloss is obtained by projecting a light beam with fixed intensity and angle onto a surface and measuring the reflected amount at an equal but opposite angle. Glossmeters are used on a variety of materials such as paint, ceramics, paper, metal and plastic product surfaces. Measuring gloss can serve companies in assuring quality of their products. Good manufacturing practices require consistency in processes and this includes consistent surface finish and appearance. Gloss measurements are carried out at a number of different geometries. This depends on the surface material. For example metals have high levels of reflection and therefore the angular dependence is less as compared to non-metals such as coatings and plastics where angular dependence is higher due to diffuse scattering and absorption. Illumination source and observation reception angles configuration allows measurement over a small range of the overall reflection angle. The measurement results of a glossmeter are related to the amount of reflected light from a black glass standard with a defined refractive index. The ratio of the reflected light to the incident light for the test specimen, compared to the ratio for the gloss standard, is recorded as gloss units (GU). Measurement angle refers to the angle between the incident and reflected light. Three measurement angles (20°, 60°, and 85°) are used for the majority of industrial coatings. The angle is selected based on the anticipated gloss range and the following actions are taken depending on the measurement: Gloss Range..........60° Value.......Action High Gloss............>70 GU..........If measurement exceeds 70 GU, change test setup to 20° to optimize measurement accuracy. Medium Gloss........10 - 70 GU Low Gloss.............<10 GU..........If measurement is less than 10 GU, change test setup to 85° to optimize measurement accuracy. Three types of instruments are available commercially: 60° single angle instruments, a double-angle type that combines 20° and 60° and a triple-angle type that combines 20°, 60° and 85°. Two additional angles are used for other materials, the angle of 45° is specified for the measurement of ceramics, films, textiles and anodized aluminum, while the measurement angle 75° is specified for paper and printed materials. A COLOR READER or also referred to as COLORIMETER is a device that measures the absorbance of particular wavelengths of light by a specific solution. Colorimeters are most commonly used to determine the concentration of a known solute in a given solution by the application of the Beer-Lambert law, which states that the concentration of a solute is proportional to the absorbance. Our portable color readers can also be used on plastic, painting, platings, textiles, printing, dye making, food such as butter, french fries, coffee, baked products and tomatoes….etc. They can be used by amateurs who don’t have professional knowledge on colors. Since there are many types of color readers, the applications are endless. In quality control they are used mainly to insure samples fall within color tolerances set by the user. To give you an example, there are handheld tomato colorimeters which use an USDA approved index to measure and grade the color of processed tomato products. Yet another example are handheld coffee colorimeters specifically designed to measure the color of whole green beans, roasted beans, and roasted coffee using industry standard measurements. Our COLOR DIFFERENCE METERS display directly color difference by E*ab, L*a*b, CIE_L*a*b, CIE_L*c*h. Standard deviation is within E*ab0.2 They work on any color and testing takes only seconds of time. METALLURGICAL MICROSCOPES and INVERTED METALLOGRAPHIC MICROSCOPE : Metallurgical microscope is usually an optical microscope, but differs from others in the method of the specimen illumination. Metals are opaque substances and therefore they must be illuminated by frontal lighting. Therefore the source of light is located within the microscope tube. Installed in the tube is a plain glass reflector. Typical magnifications of metallurgical microscopes are in the x50 – x1000 range. Bright field illumination is used for producing images with bright background and dark non-flat structure features such as pores, edges and etched grain boundaries. Dark field illumination is used for producing images with dark background and bright non-flat structure features such as pores, edges, and etched grain boundaries. Polarized light is used for viewing metals with non-cubic crystalline structure such as magnesium, alpha-titanium and zinc, responding to cross-polarized light. Polarized light is produced by a polarizer which is located before the illuminator and analyzer and placed before the eyepiece. A Nomarsky prism is used for differential interference contrast system which makes it possible to observe features not visible in bright field. INVERTED METALLOGRAPHIC MICROSCOPES have their light source and condenser on the top, above the stage pointing down, while the objectives and turret are below the stage pointing up. Inverted microscopes are useful for observing features at the bottom of a large container under more natural conditions than on a glass slide, as is the case with a conventional microscope. Inverted microscopes are used in metallurgical applications where polished samples can be placed on top of the stage and viewed from underneath using reflecting objectives and also in micromanipulation applications where space above the specimen is required for manipulator mechanisms and the microtools they hold.

Vibration Meter - Tachometer - Accelerometer -Vibrometer- Nondestructive Testing - SADT-Mitech- AGS-TECH Inc. - NM - USA Metreyên Vibrasyonê, Tachometer VIBRATION METERS and NON-CONTACT TACHOMETERS are widely used in inspection, manufacturing, production, laboratory and R&D. Please download catalogs from colored links below and let us know the brand name and model number of the product of your choice. We can offer you brand new as well as refurbished / used vibration meters, tachometers at the most competitive prices: FLUKE Test Tools Catalog (includes vibration meters, vibration testers, laser shaft alignment tool) SADT-SINOAGE Brand Metrology and Test Equipment, please CLICK HERE. In this catalog you will find some high quality vibration meters and tachometers. The vibration meter is used to measure vibrations and oscillations in machines, installations, tools or components. Measurements of the vibration meter provides the following parameters: vibration acceleration, vibration velocity and vibration displacement. This way the vibration is recorded with great precision. They are mostly portable devices and the readings can be stored and retrieved for later use. Critical frequencies which can cause damage or disturbing noise level may be detected using a vibration meter. We sell and service a number of vibration meter and non-contact tachometer brands including SINOAGE, SADT. Modern versions of these test instruments are capable of simultaneously measuring and recording a variety of parameters such as temperature, humidity, pressure, 3-axis acceleration and light; their data logger record over millions of measured values, have optional microSD cards making the able to record even over a billion measured values. Many have selectable parameters, housings, external sensors, and USB-interfaces. WIRELESS VIBRATION METERS provide the comfort of transmitting data wirelessly from the tested machine to the receiver for inspection and analysis. VIBRATION TRANSMITTERS are perfect solutions for continuous monitoring. A vibration transmitter can be used for vibration monitoring of equipment in remote or hazardous locations. They are designed in rugged NEMA 4 rated cases. Programmable version are available. Other versions include the POCKET ACCELEROMETER to measure vibration velocity in machines and installations. MULTICHANNEL VIBRATION METERS to perform vibration measurements on multiple places at the same time. The vibration velocity, acceleration and expansion in a wide frequency range can be measured. The cables of the vibration sensors are long, so the vibration measuring device is able to record vibrations at different points of the component to be tested. Many vibration meters are used primarily to determine vibrations in machines and installations revealing vibration acceleration, vibration velocity and vibration displacement. With the help of these vibration meters, the technicians are able to quickly determine the current state of the machine and the causes of the vibrations, and make the necessary adjustments and assess new conditions afterwards. However some vibration meter models can be used in the same way, but they also have functions to analyze the FAST FOURIER TRANSFORM (FFT) and display if any specific frequencies are occurring within the vibrations. These are used preferably for investigation development of machines and installations or to take measurements over a period of time in a test environment. The Fast Fourier Transform (FFT) models can also determine and analyze the 'Harmonics' with ease and precision. Vibration meters are normally used for the control rotational axis of machinery so the technicians are able to determine and evaluate the development of an axis with accuracy. In cases of emergency, the axis may be modified and changed during a scheduled pause of the machine. Many factors can cause excessive vibration in rotating machinery such as worn out bearings and couplings, foundation damage, broken mounting bolts, misalignment and unbalance. A well scheduled vibration measurement procedure helps to detect and eliminate these failures early on before any serious machine problems occur. A TACHOMETER (also called a revolution-counter, RPM gauge) is an instrument that measures the rotation speed of a shaft or disk, as in a motor or machine. These devices display the revolutions per minute (RPM) on a calibrated analogue or digital dial or display. The term tachometer is usually restricted to mechanical or electrical instruments that indicate instantaneous values of speed in revolutions per minute, rather than devices that count the number of revolutions in a measured time interval and indicate only average values for the interval. There are CONTACT TACHOMETERS as well as NON-CONTACT TACHOMETERS (also referred to as a PHOTO TACHOMETER or LASER TACHOMETER or INFRARED TACHOMETER depending on the light source used). Yet some others are referred to as COMBINATION TACHOMETERS combining a contact and photo tachometer in one unit. Modern combination tachometers show reverse direction characters on display depending on contact or photo mode, use visible light to read several inches of distance from target, the memory/readings button holds the last reading and recalls min/max readings. Just as with vibration meters, there are many models of tachometers including multi-channel instruments for measuring speed at multiple locations simultaneously, wireless versions for providing information from remote locations….etc. RPM ranges for modern instruments vary from a few RPMs to hundred or hundreds of thousands of RPM values, they offer automatic range selection, auto-zero adjustment, values such as +/- 0.05% accuracy.

Both Inch Threads as well as Metric Threads are available for fasteners. For Inch threaded fasteners external thread classes 1A, 2A and 3A as well as internal thread classes of 1B, 2B and 3B are available. These inch thread classes differ in the amount of allowances and tolerances. Classes 1A and 1B: These fasteners produce the loosest fit in assembly. They are used where ease of assembly and disassembly is needed such as stove bolts and other rough bolts and nuts. Classes 2A and 2B: These fasteners are fit for ordinary commercial products and interchangeable parts. Typical machine screws and fasteners are examples. Classes 3A and 3B: These fasteners are designed for exceptionally high-grade commercial products where a close fit is required. The cost of fasteners with threads in this class is higher. For metric threaded fasteners we have coarse-thread, fine-thread and a series of constant pitches available. Coarse-Thread Series: This series of fasteners are intended for use in general engineering work and commercial applications. Fine-Thread Series: This series of fasteners are for general use where a finer thread than the coarse-thread is needed. When compared to the coarse-thread screw, the fine-thread screw is stronger in both tensile and torsional strength and less likely to loosen under vibration. For the fasteners pitch and crest diameter, we have a number of tolerance grades as well as tolerance positions available. PIPE THREADS: Besides fasteners, we can machine threads on pipes according to the designation provided by you. Make sure to call out the size of thread on your technical blueprints for custom pipes. THREADED ASSEMBLIES: If you provide us threaded assembly drawings we can use our machines making fasteners for machining your assemblies. If you are unfamiliar with screw thread representations, we can prepare the blueprints for you. SELECTION OF FASTENERS: Product selection should ideally begin at the design stage. Please determine the objectives of your fastening job and consult us. Our fasteners experts will review your objectives and circumstances and recommend the right fasteners at the best in-place cost. To obtain the maximum machine-screw efficiency, a thorough knowledge of the properties of both screw and fastened materials is needed. Our fastener experts have this knowledge available to assist you. We will need from you some input such as the loads that the screws and fasteners must withstand, whether the load on the fasteners and screws is one of tension or shear, and whether the fastened assembly will be subject to impact shock or vibrations. Depending on all these and other factors such as ease of assembly, cost….etc., the recommended size, strength, head shape, thread type of the screws and fasteners will be proposed to you. Among our most common threaded fasteners are SCREWS, BOLTS and STUDS. MACHINE SCREWS: These fasteners have either fine or coarse threads and are available with a variety of heads. Machine screws can be used in tapped holes or with nuts. CAP SCREWS: These are threaded fasteners that join two or more parts by passing through a clearance hole in one part and screwing into a tapped hole in the other. Cap screws are also available with various head types. CAPTIVE SCREWS: These fasteners remain attached to the panel or parent material even when the mating part is disengaged. Captive screws meet military requirements, to prevent screws from being lost, for enabling faster assembly / disassembly and prevent damage from loose screws falling into moving parts and electrical circuits. TAPPING SCREWS: These fasteners cut or form a mating thread when driven into preformed holes. Tapping screws permit rapid installation, because nuts are not used and access is required from only one side of the joint. The mating thread produced by the tapping screw fits the screw threads closely, and no clearance is necessary. The close fit usually keeps the screws tight, even when vibration is present. Self-drilling tapping screws have special points for drilling and then tapping their own holes. No drilling or punching is needed for self-drilling tapping screws. Tapping screws are used in steel, aluminum (cast, extruded, rolled or die-formed) die castings, cast iron, forgings, plastics, reinforced plastics, resin-impregnated plywood and other materials. BOLTS: These are threaded fasteners that pass through clearance holes in assembled parts and thread into nuts. STUDS: These fasteners are shafts threaded at both ends and are used in assemblies. Two major types of studs are double-end stud and continuous stud. As for other fasteners, it is important to determine what kind of grade and finish (plating or coating) is the most suitable. NUTS: Both style-1 and style-2 metric nuts are available. These fasteners are used generally with bolts and studs. Hex nuts, hex-flanged nuts, hex-slotted nuts are popular. There are also variations within these groups. WASHERS: These fasteners perform many varied functions in mechanically fastened assemblies. Washers functions can be to span an oversized clearance hole, give better bearing for nuts and screw faces, distribute loads over larger areas, serve as locking devices for threaded fasteners, maintain spring resistance pressure, guard surfaces against marring, provide sealing function and much more. Many types of these fasteners are available such as flat washers, conical washers, helical spring washers, tooth-lock types, spring washers, special purpose types…etc. SETSCREWS: These are used as semipermanent fasteners to hold a collar, sheave, or gear on a shaft against rotational and translational forces. These fasteners are basically compression devices. Users should find the best combination of setscrew form, size, and point style that provides required holding power. Setscrews are categorized by their head style and point style desired. LOCKNUTS: These fasteners are nuts with special internal means for gripping threaded fasteners to prevent rotation. We can view locknuts basically as standard nuts, but with an added locking feature. Locknuts have many very useful application areas including tubular fastening, use of locknuts on spring clamps, use of locknut where assembly is subjected to vibratory or cyclic motions that could cause loosening, for spring mounted connections where the nut must remain stationary or is subject to adjustment. CAPTIVE OR SELF-RETAINING NUTS: This class of fasteners provide a permanent, strong, multiple-thread fastening on thin materials. Captive or self-retaining nuts are especially good when there are blind locations, and they can be attached without damaging finishes. INSERTS: These fasteners are special form nuts designed to serve the function of a tapped hole in blind or through-hole locations. Different types are available such as molded-in inserts, self-tapping inserts, external-internal threaded inserts, pressed-in inserts, thin material inserts. SEALING FASTENERS: This class of fasteners not only hold two or more parts together, but they can simultaneously offer sealing function for gases and liquids against leakage. We offer many types of sealing fasteners as well as custom designed sealed-joint constructions. Some popular products are sealing screws, sealing rivets, sealing nuts and sealing washers. RIVETS: Riveting is a fast, simple, versatile and economical method of fastening. Rivets are considered permanent fasteners as opposed to removable fasteners such as screws and bolts. Simply described, rivets are ductile metal pins inserted through holes in two or more parts and having the ends formed over to securely hold the parts. Since rivets are permanent fasteners, riveted parts cannot be disassembled for maintenance or replacement without knocking the rivet out and installing a new one in place for reassembly. The type of rivets available are large and small rivets, rivets for aerospace equipment, blind rivets. As with all fasteners we sell, we do help our customers in the design and product selection process. From the type of rivet suitable for your application, to the speed of installation, in-place costs, spacing, length, edge distance and more, we are capable to assist you in your design process.
