The Application of Vacuum Pressure Switch in Vacuum Coating Machine (Do not use tables)

In vacuum coating machines, vacuum pressure switches play a crucial role, and their applications are mainly reflected in the following aspects:

Monitor and control the vacuum degree

Vacuum coating machines need to carry out coating operations in a specific vacuum environment to ensure the quality and uniformity of the coating. The vacuum pressure switch can monitor the vacuum degree during the coating process in real time and convert the pressure signal into an electrical signal for output. When the vacuum degree reaches or exceeds the set pressure threshold, the vacuum pressure switch will trigger the corresponding control operation, such as starting or stopping the vacuum pump, opening or closing the vacuum valve, etc., thereby ensuring that the coating process is carried out under appropriate pressure conditions.

Ensure the quality of the coating

By precisely controlling the vacuum pressure, the vacuum pressure switch helps to improve the quality and uniformity of the film and reduce film defects. In optical coating, in order to prepare high-quality anti-reflection films, reflective films, etc., vacuum pressure needs to be strictly controlled. The vacuum pressure switch can accurately measure vacuum pressure in real time, providing reliable pressure data for the coating process and ensuring the stability and consistency of coating quality.

Realize automated production

The vacuum pressure switch can be integrated with the control system of the vacuum coating machine to achieve automated production and quality monitoring. By monitoring vacuum pressure in real time and automatically adjusting equipment parameters, the vacuum pressure switch can ensure the stability and repeatability of the coating process, improving production efficiency and product quality.

Protect equipment and systems

During the vacuum coating process, if the vacuum degree is abnormal or the pressure fluctuates too much, it may cause damage to the equipment and system. Vacuum pressure switches can promptly detect these abnormal conditions and trigger alarms or safety devices, thereby protecting the safe operation of equipment and systems.
