Each workpiece can be hard chrome plated either partially or fully. This requires a corresponding jig or model (current contacting, masks and anodes etc.) for each workpiece. Either a required plating thickness is applied or chrome plating is performed to a specific size. Such customised chrome plating operations can be performed reliably at plating thicknesses of max. 0.05 mm up to quality 7 (no rework necessary). Special processes ensure that a specific degree of gloss or a defined wettability can be achieved controllably and reproducibly. Likewise, surfaces with a customer-specified roughness are achieved.
