Our research group is looking for a more efficient method of coating a small piece of sheet metal. We have a 1.5cm x 1.5cm very thin sheet of metal that we are coating with liquid epoxy, using a brush that was provided. This method has become unacc

There are two primary causes of epoxy adhesive bond failure, heat and over exposure to moisture. Ultrasonic cavitation is a only a mechanical "scrubbing" action on a microscopic level. However, if the adhesive bond is week or has small areas of det

Hi davef, thank you for sharing this. Yes all manufacturers recommend their products, and i dont deny that they are good but for a small shop like i have i think the prices are a bit high. What i think would be a good technique, is heating the area t

USING CONDUCTIVE EPOXY: Epoxies do not bond well to tin or tin alloy surfaces. * For components: a silver-palladium or gold end termination is recommended. * For substrates: gold over nickel should work well. Remember epoxy is not hermetic, and ox

Operation features of many devices, machine components, instruments depend substantially on state of their surfaces. Selective surface processing by high-intensity energy beam (ion, electron, laser treatment) is one of the most perspective directions

If you are buying this tooling, you need to ask yourself if you really need the OEM tooling. While it is definately required for come delicate and complex connectors, for a machine like the 6T, 95% of the time you can get away with a metal block. y
