Fully automatic gold plating production line

Gold plating refers to the use of the principle of electroplating or chemical disintegration to coat a metal surface with a thin layer of gold, effectively preventing oxidation and discolouration of the metal. Gold plating process is a metal surface treatment process, mainly used to coat the metal surface with a thin film of metallic gold to improve its appearance and performance. Electroplated gold plating layer corrosion resistance, good electrical conductivity, easy to weld, high temperature resistance, and has a certain degree of abrasion resistance (such as doping a small amount of other elements of hard gold), has a good resistance to discolouration, while the gold alloy plating layer has a variety of shades, gold plating on silver can prevent discolouration. And the plating of the ductility is good, easy to polish, it is often used for decorative plating, such as plating jewellery, watch parts, works of art, etc.; also widely used in precision instruments and meters, printed circuit boards, integrated circuits, electronic tube shells, electrical contacts, etc. Requirements for long-term stability of electrical parameter performance of the parts of the electroplating. However, due to the high price of gold, the application is subject to certain restrictions.
