This process involves zinc being electro deposited on to metal parts. We can plate up to a thickness of 25um on most parts. The zinc plating is accumulated on the surface of a part, which means that the growth per surface is the same across the board. Material quality is important when it comes to zinc plating. Any defects on the base metal will be visible after plating. This means parts that are dented or scratched will still be after plating. The passivation of zinc parts in any of our four available finishes (yellow, clear, black and olive drab) improve the corrosion resistance of the parts and essentially, act as a seal for the zinc plating. Zinc plating is ROHS compliant and we can offer a ROHS compliant passivate in both colour and clear. We can also offer a ROHS compliant matt black alternative, if requested. For small parts, we can offer barrel plating.
We also offer a de-embrittling process which is essential for removing the hydrogen that has been deposited on the parts during the zinc plating and ensuring the parts do not become brittle.
