The evaporative vacuum coating machine series is not only common evaporative coating machines, such as evaporative optical coating machine, electron beam evaporative coating machine, evaporative winding coating machine, etc., all belong to the evaporative vacuum coating machine series. Evaporative vacuum coating machine is also widely used in life. It is involved in all walks of life, so there are many people who pay attention to it. Let's summarize the following to introduce the relevant knowledge of evaporative vacuum coating machine series in detail:

The equipment is mainly used for vacuum evaporation of metal film on the surface of plastic, cloth, paper, metal foil and other ribbon materials. 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, flat film, uniform film, short production cycle, low energy consumption, convenient operation and maintenance, and stable performance

Principle of evaporation vacuum coating
Vacuum coating is to place solid materials in a vacuum chamber, and heat and evaporate solid materials under vacuum conditions. The evaporated atoms or molecules can be freely dispersed on the vessel wall. When some processed substrate materials are placed in it, the evaporated atoms or molecules will be adsorbed on the substrate and gradually form a film. There are two methods for vacuum coating: evaporation and sputtering. The material used to make the film in vacuum Heat and evaporate to deposit on a suitable surface

Structural features of electron beam evaporation coating machine:
(1) The coiling system adopts high-precision branch or AC variable frequency speed regulation, which has the characteristics of stable operation, high speed, no scratch and wrinkle to the original coil, and collection of winding end face;
(2) The imported digital tension control system is adopted for tension control, which has the characteristics of constant tension and linear speed and fast action;
(3) Each group of wire feeding is independently controlled by microcomputer motor, which can be adjusted in general or separately, and has speed display;
(4) The vacuum system is well configured and the pumping speed is fast, and PLC control is adopted;
(5) Equipped with high-power power supply, high coating efficiency and good film uniformity.

The relevant knowledge of the evaporative vacuum coating machine series is not only those described above, but also more in-depth relevant technical knowledge, which will be gradually popularized later, hoping to help you.
