There are several types of vacuum evaporation, sputtering, and ion plating. They are all used to deposit various metal and non-metal films on the surface of plastic parts by distillation or sputtering under vacuum conditions. In this way, very thin surface coatings can be obtained, and the protrusions with fast adhesion are good. The advantages, but also the higher price, are less metal types that can be handled, and are generally used as functional coatings for higher grade products, for example as an internal shield. There are two common plastic plating processes: water plating and vacuum ion plating.

Vacuum ion plating, also known as vacuum coating. Vacuum plating is a relatively popular practice, the product made of strong metal, high brightness. Compared with other coating methods, the cost is low, the pollution to the environment is small, and it is widely used in various industries.
