Button Process - Plating
Electroplating is the process of electroplating a thin layer of other metal or alloy on the surface of certain metals by electrolysis. It is a process of using electrolysis to attach a metal film to the surface of metal or other materials to prevent metal oxidation ( Such as rust), improve the wear resistance, electrical conductivity, reflective, anti-corrosion (copper sulfate, etc.) and enhance the appearance and other effects. The outer layer of many coins is also electroplated.
Most of the coating is a single metal or alloy, such as titanium, palladium, zinc, cadmium, gold or brass, bronze, etc.; also has a dispersion layer, such as nickel-silicon carbide, nickel-fluorinated graphite, etc.; and cladding layer, such as steel The copper-nickel-chromium layer, the silver-indium layer on the steel, and the like. The electroplating base material includes iron-based cast iron, steel, and stainless steel, non-ferrous metals, or ABS plastics, polypropylene, polysulfone, and phenolic plastics, but the plastic must undergo special activation and sensitization before electroplating.
Protective electroplating is mainly used to prevent metal corrosion, usually using galvanizing, rhodium plating, tin plating, and the like.
Electroplating is a widely used surface optimization treatment technique in the production process of buttons. It is an electrochemical method for depositing metal and alloy plating layers on the surface of buttons. The so-called electroplating is that the metal ions in the plating solution are reduced to metal atoms by an electrode reaction under the action of an external electric field, and metal precipitation is performed on the cathode, thereby forming a plating layer on the button surface, thereby effectively changing the button's Texture, color, texture, to prevent alteration, play a role in beautifying and prolonging the service life of buttons.
