Barrel plating, strictly speaking, is called barrel plating. It is a kind of electroplating that places a certain number of small parts in a rolling barrel and deposits various metal or alloy coatings on the surface of the parts in an indirect conductive manner in the rolling state to achieve surface protection, decoration and various functions. Processing methods.

Text Barrel plating is suitable for plating small parts that cannot or are not suitable for hanging due to factors such as shape and size. It saves labor, improves labor efficiency, and the surface quality is also greatly improved, so , the invention and application of barrel plating is undoubtedly of great significance in the field of small parts electroplating. Barrel plating has become a very common electroplating method and is almost as popular as rack plating. It has been involved in dozens of plating types such as zinc, copper, nickel, tin, chromium, gold, silver and alloys.
The process of barrel plating is to put the pre-processed parts into the barrel. The parts rely on their own gravity to tightly press the cathode conductive wire in the barrel to ensure that the parts need to be plated. The current can be transmitted smoothly, and then the drum rotates in a certain direction at a certain speed. The parts continue to flip and fall after being rotated in the drum. At the same time, the metal ions are reduced to metal on the surface of the part after being affected by the electric field. plating, the fresh solution outside the drum is continuously replenished into the drum through countless small holes on the wall plate of the drum, and the lower concentration solution in the drum and the gas generated during the electroplating process are also continuously replenished through these small holes. Drain out of the barrel.
The shape of the drum is generally a hexagonal prism, placed horizontally, with an opening on one side of the drum wall plate. During electroplating, parts are loaded through the opening, and then the lid is closed. The wall plate of the drum is covered with many small holes. The cathode conductive wires in the drum pass through the central axis holes on both sides of the drum and are fixed on the conductive feet of the drum. Factors such as the size, structure, speed, conductivity, and opening rate of the barrel are all related to the production efficiency and coating quality of barrel plating. Therefore, different barrels must be designed according to different product requirements.
