Electrolytic or Electroless?
We are plating a part that is approximately ¼ inch × 1 inch. The required deposit is approximately 0.0003 inches thick. Should we consider electroless or electrolytic nickel?
Q. We are plating a part that is approximately ¼ inch × 1 inch. The required deposit is approximately 0.0003 inches thick. Should we consider electroless or electrolytic nickel? P.J.
A. The part you describe is ideal for barrel nickel electroplating. You use the word approximately in describing the thickness of the plate. Reading between the lines (and I know that one should not assume anything), I gather that the deposit does not have to be perfectly distributed over the surface of the part. If for some reason you need extremely tight tolerances, you might consider electroless nickel.
Keep in mind that electroless nickel is always a more expensive coating then electrolytic nickel, and that the physical properties of electrolytic and electroless nickel are not the same.
Choosing the best process for your operation.
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.
