Structural principle of vacuum coating machine

Membrane machine is currently the widely used equipment for making vacuum conditions. Its related components and components: mechanical pump, booster pump, oil diffusion pump, condensate pump, vacuum measurement system.
Vacuum body-Vacuum chambers have different requirements according to the processed products, and the size of the vacuum chamber is also different. At present, the widely used are 1.3M, 0.9M, 1.5M, 1.8M, etc. The chamber is made of stainless steel, and the requirements Rusty, solid, etc., there are connecting valves in each part of the vacuum chamber, which are used to connect each suction pump.Vacuum coating machine

Mainly divided into 4 parts, vacuum unit, vacuum box, evaporation system, control system.
The unit can be divided into: low vacuum, high vacuum, roots pump unit, diffusion pump unit, molecular pump unit, cryopump unit, etc.
The evaporation is divided into: electron beam evaporation, resistance heating evaporation, magnetron sputtering evaporation, multi-arc evaporation
