Vacuum plating mainly includes vacuum vapor plating, sputtering plating, and ion plating, all of which are used to deposit various metal and non-metal films on the surface of plastic parts by distillation or sputtering under vacuum conditions, which can be used to obtain very thin surface coatings with the outstanding advantage of fast and good adhesion, but they are also more expensive and can be operated with fewer types of metals, and are generally used for functional coatings for higher-grade products.
