Zinc plating involves zinc metal being electrodeposited on to components. Electro zinc offers excellent corrosion resistance and sacrificial protection. A typically thicknesses of 10-12µm with passivation can be achieved, resulting in over 500 hours salt spray test.
Our powder coating subcontractor operates a five stage pre-treatment plant using a high performance iron phosphate process to improve the adherence of paint on the zinc diecastings.
The Jig Plating process gives the highest quality finishes on our diecast components. In order to give the best results bespoke jigs have to be purchased to conduct the current and ensure that the contact points are away from the “A” face. The quality of the contacts will also determine the quality and consistent thickness of the final plating.
The range of plated finishes and the colours is vast, also various lacquers or brushing techniques give clever finishes replicating material like stainless steel, tungsten and brushed gold.
