1. Silver plating function: enhance conductivity, generally used in military communication equipment. Coating thickness is 3~8μm.
2. The role of chrome plating: to improve the corrosion resistance of the coating. Generally used in seawater-related environments, the coating for civilian products is 3~8μm, and the coating for military use is 8~10μm.
3. Dyeing function: Electrophoresis technology is mainly used to distinguish product categories. At present, most products are mainly used to distinguish locked wire nuts, and can also be used to distinguish the specifications of nuts. Coating thickness is 8~10μm.
