The vacuum evaporation coating equipment is similar to most other PVD processes, and the heat evaporation coating film also is a high vacuum processes too.

According to the different evaporation material and the different performance of the required film, it can provide different evaporation source , such as the linear, spray or special evaporator, it can be achieved super higher deposition rate.

In the operation of vacuum coating equipment must use the correct method, we will talk about how to do the correct operation!

Under the normal operation of the machine tool, start the machine, you must first open the water pipe, should always pay attention to the working water pressure.

At the same time, ion bombardment and evaporation, should pay special attention to the high voltage wire connector, can not contact, in order to prevent electric shock. Coating in the electron gun on the periphery of the aluminum bell. It is better to use lead glass to observe window glass. Glasses should be worn to observe lead glass to prevent X-ray from affecting human body. For the deposition of multi-layer dielectric film coating, ventilation and dust removal equipment should be installed to eliminate harmful dust in time. Keep flammable and toxic substances in case of fire poisoning.

Acid pickling should be carried out on ventilators and rubber gloves should be worn. Put the parts into the cleaning tank acid or alkali, to gently, no collision and splash. In addition, the commonly used pickling basin should be covered. Finally, the work is completed and the water should be cut off.

Safety regulations: the use of vacuum system, vacuum system, high temperature vacuum pump, oil adding system and vacuum coating machine may cause accidental explosion and combustion. Therefore, in the process of work, it is necessary to strictly observe the installation and operation specifications in the process of operation. It is dangerous to burn people due to heat pump experience, and the rotating parts may harm people. Therefore, it is necessary to pay attention to the inaccessibility in the production process The front cover of booster pump and diffusion pump, slide valve pump and roots pump must be complete and not accessible to people.

The winding system can be dangerous to people during operation, so the speed of the rear masking and cleaning roller is not too fast, not more than 30 m / min, and the speed is not more than 10 m / min.

Vacuum coating equipment in the operation must pay attention to these aspects mentioned above, in order to make the machine can extend the service life, in addition to the correct operation, there is also to be a good protection.
