Zinc Diecast plating problem.

I have plating problem with Zinc Die cast. It often bubbles. What can I do to prevent this? How can I strip this nickel plating off the Zinc Die-cast to start over again? Appreciate any suggestion.

Dear Steven,

Zn diecast article should be first Copper plated -followed by Nickel or Nickel/chrome plating.

To remove the nickel plating the best method is to sand blast the bubbling effect could be to impurities and/or hydrogen embrittlement,
