For different reasons plastic components can be metallised with different techniques. Circuit boards, which are a typical example for functional coating, are mostly galvanised. For decorative (metal gloss), optical (reflection) and functional (e.g. ESD) demands as well, we use PVD (physical-vapor-deposition). For each purpose, we offer special process variants.

Our metallisation units can extrude different materials. In every case this occurs in fine vacuum, whose creation is only possible with multi stage pump sets. The pumping times have major influences on the processes economic effiency. Towards reaching the required vacuum the thermal evaporation of the coating material is started. The material precipates everywhere in the chamber and more importantly on the components. One or multiple layers can be extruded successively. To achieve constant layer thickness the components are revolving. Usually the thermal exposure is very little so that very sensitive materials can be coated as well.

Often, especially with coatings for decorative demands, we use coatings with multiple layers. The undercoat (a reflective lacquer), the metal (often aluminum because of it high reflection level) and the top coating form a unit, to fit their purpose. We are well equipped to solve these tasks. Our philosophy applies here too. You get it first hand. Starting with complex injection parts to their metallic surface.
