Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis.
It is a process of using electrolysis to attach a metal film to the surface of a metal or other material to prevent metal oxidation ( Such as rust),
improve wear resistance,
electrical conductivity,
reflectivity,
corrosion resistance
enhance aesthetics
the current process for partial silver plating on the inner teeth of the nut can only be coated with shielding paint or glue Method, low production efficiency, high cost of water and electricity
