Zamak, Za-8, or Other Cosmetic Finish for Zinc Die Castings

Q. We are needing cosmetic metallic finishes on about 100,000 small zinc die castings (zamak and/or za-8) per yr.

Could anyone suggest a cost effective process? thanks.

A. Hi, Kevin. You can plate these items with just about any metal you wish. Nickel or electroless nickel sound like likely choices.

Hi, Anil. Any reason to not just lacquer or clearcoat them for corrosion resistance?

Regards,
