Chromium Plating of Zinc Diecasts
Q. We are starting a manufacturing facility to plate zinc diecast faucet handles. What is the best way to set up a chrome plating line? I require complete information for the setup of the process. –M.S.
A. I receive questions regarding the design of plating facilities quite often. As much as I would like to answer these questions in this column, I am not able to because of the extensive amount of time and effort involved. A project of this type must be done on a consulting basis.
There are a number of books that have been written in the last 20 years that discuss decorative chromium plating, many of which are available through Amazon.com. If you are new to the world of electroplating, I suggest a basic training program from the Kushner Electroplating School, platingschool.com (I am no longer affiliated with the school.), or the National Association for Surface Finishing, nasf.org.
Our expert, Art Kushner, says yes, you can color stainless steel, but it is not a process that is typically performed in a plating shop. Read more about his answer.
Why is it important for you to know this?
Masking is employed in most any metal finishing operation where only a specifically defined area of the surface of a part must be exposed to a process. Conversely, masking may be employed on a surface where treatment is either not required or must be avoided. This article covers the many aspects of masking for metal finishing, including applications, methods and the various types of masking employed.
