Selective coating

The term comes from "selection". This means that only certain sections/parts should or must be coated.

If, for example, some areas of the component are exposed to severe weather conditions, greater wear/ higher abrasion or a high risk of corrosion, selective coating is recommended. Also, if demarcated areas must remain coating-free to create a grounding point.

Selective coating can be done in a conventional way, e.g. by covering areas that remain free, or it can be done by special selective coating equipment. In these processes, the electrolyte, i.e. the coating medium, is fed to the component. In the conventional electroplating process, the component is transported to various coating containers.
A component-specific coating system is required in which the corresponding workpiece is enclosed, protected from light and water.

The component is then connected to a direct current source in the container and acts as a cathode.
