What is the electroplating process for brass handles

  Brass handle electroplating is a common surface treatment process that improves the appearance of the handle and improves its corrosion resistance and wear resistance. Commonly used plating layers include nickel, chromium, copper, gold and silver. The following are the general process points of brass handle electroplating:

  1. First, it is necessary to remove grease, dirt and any organic residue on the surface of the brass hardware handle. The common method is to use solvent cleaning or soak in an alkaline bath.

  2. Improve the activity of the brass surface of the cabinet handle to better adsorb metal ions in the  electroplating solution. Activation treatment can be completed by chemical etching or weak acid pickling.

  3. Before formal electroplating, sometimes a thin layer of base metal is plated on the brass surface to improve the adhesion and uniformity of subsequent plating.

  4. When formally carrying out the electroplating process, it is necessary to pay attention to the control of time. The length of time determines the thickness of the electroplating layer.

  5. After the electroplating is completed, it is cleaned. After the handle is removed from the electroplating tank, it is necessary to thoroughly clean the residual electroplating solution with running water, and then dry it to prevent water marks and rust.

  6. Check whether the coating has defects, and pack and store or assemble and use directly after confirming that it is qualified.

  The electroplating process can not only change the appearance of brass cabinet handles, making them present various metallic colors, but also extend the service life and enhance the product value.
