At present, pvd coating machine is the most widely used equipment for coating products under vacuum conditions. A complete vacuum coating machine consists of many parts of systems, each of which performs different functions to achieve the final high-quality coating. Its components include vacuum chamber, vacuum testing system, vacuum pumping system, film forming control system, oil diffusion pump, Roots pump, condensate pump, mechanical pump, etc.

The main body of the vacuum coating machine is the vacuum chamber. The size of the true chamber is determined by the processing product, and its size can be customized. The chamber is generally made of stainless steel, which requires durability and no rust. The vacuum chamber has many connecting valves used to connect various auxiliary pumps.
The vacuum pumping system is composed of mechanical pump, diffusion pump, Roots pump, etc. The vacuum pumping system is an important component of the vacuum system of the coating machine, and the level of vacuum directly affects the coating effect of the product. The vacuum degree is obtained by the vacuum testing system.
The film forming control system can use different methods, such as fixed plating time, visual inspection, extreme value monitoring, crystal oscillation monitoring, etc. There are also many coating methods, including ion evaporation coating and Magnetron sputtering coating. The film deposited by Magnetron sputtering has strong adhesion and high purity, and can be sputtered with a variety of materials with different components. Ion evaporation coating can improve the density, adhesion and uniformity of the film.
pvd coating machine is usually customized according to the actual product process needs, with the cost of hundreds of thousands to tens of millions. Machines and equipment that use manual operation are relatively cheap, usually around a million yuan. Machines and equipment with high technological content that can achieve complete automation will cost several times more. Domestic well-known enterprises can achieve semi-automatic operations, while a few with strong technology can achieve complete automation
