Satin nickel plating process

A discussion started in 1999 and continuing through 2009.
Add your Q. or A. to restore it to the "Current Topics" discussions.

(1999)

Q. Dear Sir, I would like your advice on:-

1) SATIN NICKEL PLATING ON ZINC DIE CASTING BASE METAL ELECTROPLATING.
2) An exhaustive trouble shooter for the same.
3) Help to maintain the bath for zinc and copper tolerance and the remedy to it.
4) Help on filtering process and the available media and the sequence of the process. 5) Duration of the emulsifier life etc.

Awaiting an earliest acknowledgement. Thanking you in anticipation.

A. These answers are usually included in the technical data sheet for the process, Manish. If your vendor cannot supply them, the next best resource might be The Canning Handbook, which has a chapter on satin nickel which covers most of these questions. Good luck!

A. Satin nickel is a very delicate process. It needs every day filtering, special agitation etc. As Ted already mentioned, your vendor must have all the answers to your questions (I hope you have a vendor and you are not trying a home brewing product). If not, look for another supplier.

A. Two excellent reference books, one of which is more practical and one of which is more theoretical are:

"Electroplating of Zinc Diecastings" [link is to product info at Amazon], S.K. Jalota
"Nickel and Chromium Plating" [link is to product info at Amazon], J.K. Dennis and T.E. Such.

These will start you on the beginning of understanding both Nickel Plating and Zinc Diecastings as a substrate.

A. Satin Nickel is quite a complicated plating process. Be happy if you are able to operate such a process with the help of a supplier. Don't try to do a home brewing formula.

Satin Nickel on Zinc Diecast

March 18, 2009

Q. LOOKING FOR A STEP BY STEP ITINERARY TO ACHIEVE A SATIN FINISH ON ZINC DIE CAST. I AM CURRENTLY RUNNING A CYANIDE CU. AND A VERY GOOD CUSTOMER OF OURS HAS ASKED THAT I SEND THEM A STEP BY STEP PROCESS. FOR THEIR FILES I HAVE SEEN IN YOUR FINISHING BOOK THAT WE RECIEVE A STEP BY STEP PROCESS BEFORE BUT PRESENTLY I DO NOT HAVE THAT ISSUE AND I AM BEING PRESSED ON THIS ISSUE. THANK YOU FOR YOUR TIME.

A. Hi, Rick. Finishing.com is a website where finishers meet and discuss stuff ... we have no book or magazine (you may be confusing us with Elsevier-owned "Metal Finishing".

I think the easiest, but not the only, way would be to do acid copper plating after your cyanide copper plating, then a conventional Watts nickel, then a proprietary satin nickel that you buy from a vendor specializing in that process.

But it's very important that you and your customer agree on what you mean by "satin nickel" -- to some it apparently means a very fine brushed finish, to some others it means a "bead blast" finish, and to many if not most platers it means a pearlescent finish. Obviously, you achieve these three different finishes by brushing, bead blasting, or special additives.
