Decorative Coatings

Refinement of surfaces via decorative coatings has become a major industrial application in the field of automotive, cosmetics, smartphones, and luxury bathroom fixtures. The purpose of applying the coating may be decorative, functional or both.

Application requirements

  • Carbon free vacuum

  • Long maintenance intervals and maximum uptime

  • Low operating costs

  • Simplest on-site maintenance

How does it work?

The part to be coated is inserted into a chamber and coated with either a PVD or CVD process. The process itself is a sputtering process in which a plasma is generated under vacuum which enables the deposition on the part. The vacuum inside the chamber is typically in a range between 10-3 to 10-4 hPa. A carbon free vacuum is essential to guarantee a high quality surface.

Product portfolio

Pfeiffer Vacuum supplies this application since the beginning with the right product portfolio and expertise. For the vacuum generation we offer dry and oil lubricated pumps as well as complete pumping systems. To reach a lower pressure, we offer hybrid and magnetic levitated turbopumps. We also offer leak detectors and pressure gauges to ensure process stability and safety.
