In daily life, there are many products coated with a layer of film by a vacuum coating machine, which are applied to all walks of life, tableware, furniture, bathroom, digital products, packaging products, knives, touch tools, vehicles, etc. The vacuum coating machine is coated with a thin film layer, which not only changes the performance, but also changes its aesthetics. However, many customers who are not particularly familiar with vacuum coating machines will be more curious about the specific conditions for vacuum coating machines to work normally. The following is a vacuum editor to introduce you in detail, hoping to help you:

1. Normal working conditions of vacuum coating machine
       1. Ambient temperature: 10~30℃
       2. Relative humidity: not more than 70%
       3. Cooling water inlet temperature: not higher than 25℃
       4. Cooling water quality: urban tap water or water of equivalent quality
       5. Power supply voltage: 380V, three-phase 50Hz or 220V, single-phase 50Hz (depending on the needs of the electrical appliances used), the voltage fluctuation range is 342~399V or 198V~231V, and the frequency fluctuation range is 49~51Hz;
       6. The pressure, temperature and consumption of compressed air, liquid nitrogen, hot and cold water, etc. required by the equipment should be stated in the product instruction manual.
       7. The surrounding environment of the equipment is clean and the air is clean, and there should be no dust or gas that can cause the surface of electrical appliances and other metal parts to corrode or cause conduction between metals.
       In addition, the laboratory or workshop where the vacuum coating machine is located should be kept clean and hygienic. The floor is terrazzo or wood painted floor, no dust. In order to prevent the gas discharged from the mechanical pump from polluting the laboratory environment, the method of installing an exhaust pipe (metal or rubber pipe) above the exhaust port of the pump can be used to discharge the gas outdoors.
