Product description

Selective coating means precise treatment of defined surface areas. The advantage of the selective coating is that any mechanical reworking of the surface is eliminated. Component surface areas which are to be left uncoated are covered, inside a tool, with an integrated sealing system. An electrolyte is pumped from a reservoir into the tool and it passes between the free component surface and the tool housing. We are able to create selectively a hard anodised layer on defined areas of a component. On the other hand, we can also partially deposit metal, such as hard chrome and gold. While with hard anodising and hard chrome wear resistance is in the foreground, the main characteristic with gold is the electrical conductivity. For partial wear protection of aluminum components, partial oxidation by laser may be considered.
