Vacuum metallising, or PVD (Physical Vapour Deposition), is the process of physically plating a metal material onto a plastic part in a vacuum chamber. Another term that is used is Plating on Plastic (POP).
The evaporation of the metal occurs by metal wire being in contact with a heat source (electrically charged tungsten filament) in a closed chamber under high vacuum.
The lack of pressure lowers the boiling point of the metal which causes the liquid metal to change to a gaseous phase. The metal vapour encounters the oxygen in the air forming a stable oxide layer on the surface of the components.
This gives the component an environmentally friendly, decorative metallic coating (check out our Gallery to see finished products). Metallised plastic components can be recycled and is a great alternative to traditional metal shrouds or over-shelled options which can’t be easily separated for recycling.
Typically, spray painting is a two-part process, involving a base coat, which is sprayed on and then cured in an oven, and then a top coat is applied.
Metamor has years of experience in providing innovative and custom spray finishes.
We offer several special effects, for example:
