The influence of the cleanliness of the coating process of PVD vacuum coating machine

The cleanliness of the coating process of the PVD vacuum coating machine is a major indicator that affects the adhesion of the vacuum coating film. Therefore, in order to avoid vacuum pollution, the surface cleaning of equipment parts is very important.

Vacuum coating technology is a novel material synthesis and processing technology, and it is an important part of the field of surface engineering technology.

Vacuum coating technology is the use of physical and chemical means to coat a solid surface with a special performance coating, so that the solid surface has wear resistance, high temperature resistance, corrosion resistance, oxidation resistance, radiation protection, electrical conductivity, magnetic conductivity, insulation and decoration And many other superior properties that are superior to the solid material itself, to achieve the effect of improving product quality, extending product life, saving energy and obtaining significant technical and economic benefits. Therefore, vacuum coating technology is hailed as one of the more promising and important technologies, and has shown attractive market prospects in the development of high-tech industrialization.

　　It is mainly used for coating under high vacuum, and it is used in many industries, such as automobile, medical, transportation, machinery, service and other industries, and it is also a coating equipment that is very close to people's lives.

　　Vacuum coating equipment is an important part of the coating industry. Without advanced and efficient coating machines, there would be no modern coating industry.

　　Vacuum coating will encounter film drop. What is the reason for this situation and how to solve these problems?
