Summary for waviness in nickel chrome plating Discussion
Waviness problem in nickel chrome plating on ABS plastics appears only after the electroless and copper steps, even though the parts look good after acceleration. The thread excerpt does not include a direct troubleshooting answer, but it points readers to several reference books on electroplated plastics for process guidance: *Standards and Guidelines for Electroplated Plastics* by the American Society for Electroplated Plastics, *Plating of plastics: Recent Developments* by John McDermott, *How to Electroplate Non-Metallics* by Warner Electric Co., and *Practice of Plating on Plastics* by Ralph W. Furness. The advice implied by the post is that the defect likely needs investigation in the plastics plating process between acceleration, electroless deposition, and copper plating, using established references rather than assuming the problem is in the later nickel-chrome finish alone.
Q. We doing Nickel Chrome Plating on ABS plastic we found waviness problem after copper plating, Until acceleration the parts are good, after electroless and copper the problem is visible.

A. Dear sir
many reasons may cause this
1- NO proper cleaning cycle,
2- etching is not strong enough or not sulphuric & chromic balanced,
3- as I can see from your photos acidic copper bath is not in good condition.
My advice is to make new small test Tanks to find the reason.
