What is precision plating

Precision plating (including some processes related to the chemical surface film-forming reaction in the liquid phase) can give various metal and non-metal devices a beautiful appearance and excellent abrasion resistance and wear resistance, and can make the surface of the device obtain more This special function makes it a new type of functional material, and it can even be used as a means to form some metal matrix composite structural materials.

Precision plating | the role of electroplating additives

In order to improve the performance of the plating solution and the quality of the coating, a small amount of certain organic (or inorganic) substances are often added to the plating solution, which is an additive. Additives, the result is a sponge-like deposit. After adding the additives, the coating is dense, fine and bright.

Precision plating | the role of electroplating additives


Gold is the ultimate precious metal for electrical contact plating. For that reason, the electrodeposition of gold is used extensively in electrical component applications such as electrical contacts, connector pins, switches, sensors, and many others for which repeated physical contact occurs. Gold-plated parts exhibit excellent wear resistance, high hardness, corrosion resistance, high conductivity, solder-ability and excellent performance at high temperatures. We offer not only 24-karat gold plating but a variety of gold plating that exhibits the following benefits:

  • Gold will not form surface oxides
  • Gold conducts low voltage currents for long periods of time without corrosion or failure
  • Gold provides good wear resistance, especially when combined with cobalt or nickel

Precautions for surface treatment of precision electroplated aluminum alloy

The hard anodic oxide film on the surface of aluminum and aluminum alloy has high hardness and excellent wear resistance. It is a common method to improve the wear resistance of aluminum parts. In order to improve the service life of The quality anodized film layer has a relatively large thickness. Therefore, after the aluminum parts are hard anodized, the final size of the parts will change significantly. This rule is usually followed, which is the increase in the final size of the parts, which is roughly equal to the film 1/2 of the layer thickness, as shown in the figure. This value is widely used to estimate the size change of aluminum parts after hard anodization.

Frequently Asked Question

Do you have any question?

Products plated by PPC are integral in some of the manufacturing world’s most complex assemblies. Our metal plating finishes are found in safety-critical devices, such as ABS modules, drive-by-wire controls, commercial and military aircraft, and implantable medical devices.

Masking tape is used for precision electroplating to cover the electroplated parts that are not electroplated.

Precision electroplating usually means that the original tolerance of the parts that need to be electroplated (oxidized) is small, generally within 0.01mm. On the premise of meeting the product functionality, after electroplating (oxidation), the size of the parts can still meet the original tolerance requirements .
