Do you know the operation steps of vacuum coating equipment?

With the continuous innovation of the process development of vacuum coating equipment, the design of hard film is also developing towards the direction of diversification and multi film. So far, it has become the choice of coating process for modern enterprises. In fact, the normal operation of the coating machine should refer to the instructions in the operation manual. Today, the coating equipment manufacturer will share simple operation methods:

1. Check whether each operation control switch of vacuum coating equipment is in the "off" position.

2. Turn on the main power switch and power on the vacuum coating equipment.

3. Low pressure valve pulled out. Open the air charging valve. After no sound of air flow is heard, start the bell jar valve to raise the bell jar.

4. Install the fixed tungsten spiral heater. Fix PVDF film and aluminum cover plate on the rotating disc. Put the aluminum wire into the spiral heater. Clean all parts in the bell housing to ensure that there are no impurities and dirt.

5. Lower the bell jar.

6. Start the mechanical vacuum pump of vacuum coating equipment.

7. Turn on the power supply of composite vacuum gauge (model of composite vacuum gauge: Fzh-1A).

8. Multi arc ion coating machine When the pointer in the low vacuum gauge "2" moves clockwise to 6.7Pa again, the low pressure valve is pushed in.

9. The vacuum coating equipment shall open the cooling water, start the diffusion pump and heat for 40min.

10. Low pressure valve pulled out. Repeat the ⑦ action procedure for the vertical single door coater once: turn the lower left knob "1" to the measurement position of section 2. The pointer in the low vacuum gauge "2" moves clockwise. When the pointer moves to 6.7Pa, open the high pressure valve.
