There are some potential safety hazards and skills when the vacuum coating machine is turned on and off. For familiar staff, they are familiar with the way, but for new people, they need to pay attention to it in order to ensure that everything is safe.

(1) Master the "vacuum coating machine Safety Operating Procedures".
(2) Before starting the machine, check whether the water, electricity, and gas are normal. The cooling water pressure can generally be above 0.2MPa, the gas pressure can be above 0.4Mpa, and the voltage can be between 370-390V.
(3) Startup steps: Pneumatic mechanical pump, after about 30 seconds, open the front stage valve, open the composite vacuum gauge, and wait for the front stage to draw below 10Pa and stabilize before starting the diffusion pump (you must go to the back to check if the electric furnace wire turns red).
(4) Shutdown steps: Turn off the ionization meter, close the high valve, cut off the power supply of the heater, use the front stage pump to naturally lower the front stage to room temperature, close the front stage pipeline valve, stop the mechanical pump, stop the cooling water, power outage, and gas shutdown.

Coating system configuration of vacuum coating machine
We believe that since the coating equipment serves coating production, the coating system we design and manufacture must adapt to the user's production process, rather than letting the user change the production process to adapt to our coating machine------ Frank Zimone

In the past 15-20 years, optical thin film plating equipment has undergone remarkable changes. Previously, most coating machines were operated purely manually, and the most advanced were only semi-automatic controls, requiring high-level operators to ensure the consistency of coating products. Now, the high-quality optical vacuum coating machine is a fully automatic system integrated with a series of intelligent modules (subsystems). These intelligent modules (subsystems) are usually formed into a local area network (LAN) under the instructions of multiple microprocessors, which can be integrated into the entire factory's automatic control system.

The continuous increase in user experience has made their requirements for equipment performance increasingly stringent, to the extent that we now find it easy to find that users require manufacturers to provide relevant process technology while purchasing coating machines. This paper discusses the subsystems and components that can be used in today's optical coating system, and the decisive role of coating technology in component selection and vacuum chamber configuration. Although other technologies are becoming increasingly popular, considering that physical evaporation is still the most applicable and widely used method, the discussion in this article only involves physical evaporation technology.
