Barrel plating equipment production line, micro barrel plating machine, variable speed barrel plating machine, electroplating drum

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 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. Therefore, 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 that 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 plating process is to put the pre-treated parts into a drum. The parts rely on their own gravity to tightly press the cathode conductive wire in the drum to ensure the current required when the parts are plated. It can be transferred smoothly. 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 restored to metal coating on the surface of the parts after being affected by the electric field. , the fresh solution outside the drum is continuously replenished into the drum through countless small holes on the wall plate of the drum, while the lower concentration solution in the drum and the gas generated during the electroplating process are also continuously discharged through these small holes. outside the barrel.
The shape of the barrel is generally a hexagonal prism, placed horizontally, with an opening on one side of the barrel 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, rotational speed, conductivity mode and porosity of the barrel are all related to the production efficiency and coating quality of barrel plating. Therefore, different rollers must be designed according to different product requirements.
