DEMGY Deva specializes in the production of large series of industrial parts using completely automated processes.  We carry out surface treatments, mainly chromium plating, but also painting and zinc plating of all kinds of parts.

Chrome plating of automotive parts is DEMGY Deva's specialty. Chrome plating gives parts a more aesthetic and metallic aspect. Zinc plating protects metal parts from corrosion but does not have a decorative purpose. Paint is used to decorate parts.

Parts go through a careful, manual quality control before we deliver them to the customer for assembly.
