Oil mark issue in satin nickel plating
February 21, 2012
Q. Hi everyone.
I need some help and advise on oil mark problem in satin nickel plating.
We plate a small ABS plastic part. After plating in satin nickel, we found that a lot of oil mark NC.
Base on our experience & know-how about satin nickel, we have done few step/counter measure to eliminate this problem like do carbon treatment & peroxide treatment on satin-Ni solution to remove aging additive, adjust the satin additive dilution factor, clean plating tank & water rinse tank with special chemical and do an additional filtration/treatment with filter aid to the satin nickel bath. But this matter still unresolved.
Please give some idea on the other thing that is possible to look into or maybe I can't see to solve this matter.thank you.

If you feel that you are not getting oil from the plating tank, take a very hard look at the tanks ahead of the plating tanks. It is not uncommon to have an oil slick on one or more and it will carry over to follow on tanks.
