Pin electroplating with pinpoint accuracy
Pin electroplating is an ideal addition to the familiar bath applications. In pin or pad electroplating, the component or piece of jewellery to be plated is attached to the negative pole of the electroplating system. Customised anodes are encased in a cotton pad. The liquid absorbed in the pad is sufficient for the electroplating process, whereby the anode is moved evenly over the surface to be coated. The desired metal layer is created by the migration of the metal ions from the electrolyte to the cathode.
Due to the special and small components, pin electroplating can be used flexibly in terms of space and offers a wide range of possible coatings. The high flexibility and reliability of this process make it particularly suitable for repairing small jewellery parts.
Pen plating offers numerous advantages
- Minimisation of costs through on-site repairs
- Targeted coating of partial surfaces possible – targeted repairs
- Coating of difficult geometric areas or selective recoating possible in the event of adhesion problems
- No time-consuming masking work for bicolour applications
- Process can be used with all electrically conductive materials
- Very good corrosion resistance
- Immediate usability of the jewellery parts after processing
We have the right electrolytes
Our electrolytes specially developed for pin and pad electroplating are ideal for multi-colour applications or for repairing and restoring your jewellery parts. The rhodium, ruthenium or gold baths deposit high-gloss, abrasion- and corrosion-resistant layers for all decorative applications.
