What is Brushplating?

TEI Main Site | Selective Plating | FAQ's | What is Brushplating?

The theory of brush plating is very basic. The part to be plated is given a negative (-) charge through a flexible wire lead from a special D.C. power pack. The plating tool or "brush" is positively (+) charged from the same power pack by a second insulated flexible lead. The plating tool assembly consists of an insulated handle with a graphite or stainless steel anode.

The anode is covered with an absorbent material such as dacron felt. The plating tool is then dipped into the desired plating solution and rubbed over the area where the coating is desired.

The plating only takes place where the anode contacts the part. The operator must maintain movement between the anode and the part to insure sound metal deposits.
