This paper briefly introduces the series of electron beam evaporation vacuum coating machine

Evaporation series winding coating equipment is mainly used for vacuum evaporation of metal film on the surface of strip materials such as plastic, cloth, paper and metal foil. Products are widely used in packaging, printing, anti-counterfeiting, textile, electronic industry and other fields. This series of equipment has the characteristics of stable operation, flush retraction and release coating, uniform film layer, short production cycle, low energy consumption, convenient operation and maintenance, stable performance and so on

Principle of vacuum coating by evaporation

Vacuum coating is to place solid materials in a vacuum chamber, heat and evaporate the solid materials under vacuum conditions, and the evaporated atoms or molecules can be freely distributed on the wall of the container. When some processed substrate materials are placed in them, the evaporated atoms or molecules will be adsorbed on the substrate and gradually form a thin film. There are two methods of vacuum coating, one is evaporation and the other is sputtering. The material for making the film is heated and evaporated in vacuum to deposit it on a suitable surface.
