Hardness testing and electroplating of stamping parts

The stamping parts need to be sprayed with a layer of primer before electroplating, so that the effect of electroplating will be very good, and the anti-corrosion time will be longer. For example: gold plating: improve conductive touch impedance and enhance signal transmission. (Gold is stable and expensive.) Silver plating: Improve conductive touch resistance and enhance signal transmission. (Silver has good function, simple oxidation, and conducts electricity after oxidation) Copper plating: used as a primer to improve the adhesion of the electroplating layer and the ability to resist corrosion. (Copper is simply oxidized. After oxidation, the patina is no longer conductive, so copper-plated products must be protected by copper) Nickel plating: used for primer or appearance to improve corrosion resistance and wear resistance. Wear resistance can exceed chrome plating). Stamping parts need to improve conductive touch resistance, enhance signal transmission, and have higher wear resistance than gold. Tin-lead plating: to improve soldering ability, it will soon be replaced by other alternatives (because of lead, most of them are now plated with bright tin and matte tin). Because the elastic discharge mold operation is more convenient than the fixed discharge mold, the operator can see the strip The feeding action in the mold, and the elastic force is applied to the strip when unloading by the elastic unloading plate, which will not damage the surface of the workpiece. Therefore, in the actual planning, the elastic unloading plate is used as much as possible, and as long as the elastic unloading plate is unloaded When the material force is insufficient, the fixed discharge plate is used instead. Whether the mold used by the stamping parts manufacturer chooses an elastic unloading plate or a fixed unloading plate depends on the size of the unloading force, during which the material thickness is the primary consideration. The hardness test of metal stamping parts selects Rockwell hardness tester. Small, messy-shaped stamping parts can be used to test the surface is very small, can not be tested on the ordinary desktop Rockwell hardness tester. Alloy stamping parts are commonly used parts in the field of metal processing and mechanical manufacturing. Stamping processing is a processing method that uses molds to separate or shape metal strips. Its use scale is very wide. Because the consumption of materials in the processing of stamping parts is not very large, after plastic deformation, the structure of the material will be changed and improved, which can make the processed stamping parts have some strength in terms of strength. improve. The performance of the stamping parts in terms of dimensional accuracy is also considerable. The uniformity and consistency of the scale can be maintained in the same module. Secondly, during the stamping process, the stamping parts processing manufacturer found that the appearance of the raw materials would not be damaged in any way, so its appearance quality was still very good, and the appearance was smoother and more beautiful. In the later surface painting and electroplating operations, both Can provide convenience. The power used by the equipment during processing is conventional power and special power to ensure the size and shape of the product.
