An Overview
Vacuum metalization is a method for applying a very thin layer of metal to a surface. This metal layer usually consists of aluminum although other metals such as silver, copper, chrome, and gold can be used. Vacuum metalization consists of the metal being heated in a vacuum, evaporated into molecules, and the molecules are sprayed on the cooled surface of the shield. This results in a thin layer of the metal being deposited on the surface. This method achieves a high standard of finish at a low cost.
Vacuum metalization is used to produce a type of EMI (electromagnetic interference) shielding. This shielding is formed into the desired shape to facilitate its use within an electronics device and then vacuum metalized with the metal layer.
Vacuum metallization is also used to apply a chrome coating on aluminum and steel substrates, for example vehicle wheels, hub caps, and bumpers for aesthetic purposes.
