Frequently Asked Questions
Answer: Electroplating is a process commonly known as Electrolysis. Electrolysis producing a chemical change by passing an electrical current through to the electrolyte (solution). The ions migrating to the electrodes, the positive ions which are the metal being deposited are attracted to the negatively charged electrode (the part being plated). The negative ions are attracted to the positive electrode (Anode) and given off as gases.
Answer: 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 ensure sound metal deposits.
Answer: Industries that use Electroplating Services include Navy & Marine, Aircraft & Aerospace Industries, Printing Industries, Electrical & Electronic Industry, Forest, Logistics and General Engineering including Mould and Die Manufacturers.
Answer: When it comes to Brush Plating the difficulty lies with plating large or complex shapes. In most cases, only one part at a time can be plated and it is a very labour intensive operation.
Answer: Selective plating means that you can selectively plate an area by the means of masking off areas that need not be plated with either masking tapes or masking paints. Just like painting the material on. The job becomes the canvas or Cathode and the brush is the Anode and the paint is the metal.
