The evaporation series roll to roll coating machine is mainly used for vacuum evaporation of metal films on the surface of ribbon materials such as plastic, cloth, paper, and metal foil. The 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 and even film deposition, short production cycle, low energy consumption, convenient operation and maintenance, and stable performance
The principle of evaporation vacuum coating is to place solid materials in a vacuum chamber, and under vacuum conditions, heat and evaporate the solid materials. The evaporated atoms or molecules can freely spread onto the walls of the container. When some processed substrate materials are placed inside, the evaporated atoms or molecules will gradually adsorb onto the substrate to form a thin film. There are two methods for vacuum coating, one is evaporation and the other is sputtering. Heat and evaporate the materials used to make thin films in vacuum, allowing them to deposit on appropriate surfaces.

The structural characteristics of the electron beam evaporation roll to roll coating machine:
1. The winding system adopts high-precision branch or AC variable frequency speed regulation, which has the characteristics of stable operation, high speed, no scratch or wrinkle on the original coil material, and collection of winding end faces;
2. The tension control adopts an imported digital tension control system, which has the characteristics of constant tension, constant linear speed, and fast action;
3. Each group of wire feeding is independently controlled by a microcomputer motor, which can be adjusted overall or individually, and has a speed display;
4. The vacuum system is well-equipped with fast pumping speed and adopts PLC control;
5. Equipped with high-power power supply, high coating efficiency, and good film uniformity.
