RE-PLATING OF PLATED PARTS




CAN YOU RE- ZINC PLATE & YELLOW PASSIVATE PARTS AFTER RE-WORKING ON THEM (EG: OPENING OF HOLES) - TO SAVE UNNECESSARY STRIPPING OF EXISTING ZINC PLATE?

There is nothing to save. The existing Zinc will be easily removed by the acid step in the replating process.

To repair the coating without stripping it I would suggest Brush Plating the areas affected with Brush Zinc Plate solution. If you can't do it in-house there are plenty of plating shops in the UK that can.

Hello Mike,

Yes, there is a way to replate the area without removing the exisitng Zinc. The process of brush electroplating was designed and is used for this exact application.

Techniques have been formulated that will allow a technician to activate the repair area without removing the adjacent zinc coating.

The only real problem is when a chromate or other conversion coating is used, the colors will not be an exact match.

This process is used in many industries, and can be performed on site as the process is portable.

All the best,
