There are many types of pvd coating machine, which can be divided by model and industry. According to the industry, it can be divided into: optical vacuum coating equipment, decorative pvd coating machine, functional coating coating equipment, semiconductor pvd coating machine, auto parts vacuum coating equipment and so on. The application industry is different, the model is different, and the size is different, including the coating technology is more or less different. So what are the structures of general pvd coating machine?

pvd coating machine is the most used equipment for coating products under vacuum conditions. A complete vacuum coating machine is composed of multi-part systems, each system can complete different functions, so as to achieve the final high-quality coating , its composition includes vacuum chamber, mechanical pump, vacuum test system, oil diffusion pump, vacuum pumping system, condensate pump and film forming control system and so on.
The main body of the pvd coating machine is a vacuum chamber. The size of the vacuum chamber is determined by the processed product. Its size can be customized. The chamber is generally made of stainless steel, which is required to be strong and durable without rusting. The vacuum chamber has many connection valves for connecting various auxiliary pumps.
The vacuum pumping system is composed of mechanical pump + diffusion pump + Roots pump. The vacuum pumping system is an important part of the vacuum system of the coating equipment. The degree of vacuum directly affects the coating effect of the product. The vacuum degree is obtained from the vacuum test system. Data.
The film formation control system can use different methods, such as fixed plating time, visual inspection, extreme monitoring, and crystal oscillation monitoring. Coating methods are also divided into a variety of processes, commonly used ion evaporation coating and magnetron sputtering coating. The film deposited by magnetron sputtering has strong adhesion and high purity, and can be used to sputter a variety of materials with different compositions. Ion evaporation coating can improve the compactness, bonding force and uniformity of the film.
The coating principle of pvd coating machine is generally customized according to the actual product process requirements. The cost is basically in the hundreds of thousands to tens of millions. The machines and equipment using manual operation are relatively cheap, generally around one million, with high technical content and can be fully automated. The cost of machinery and equipment is several times higher, and the cost of machinery and equipment that can be fully automated by well-known domestic enterprises will be several times higher. Well-known domestic enterprises can achieve semi-automatic operations, and a few with strong technology can achieve complete automation.
