The surface treatment is mainly used in surface coating is relatively rare, a lot of metal materials, coating the surface of the conductor material is used for processing. And said to the vacuum coating machine is a kind of typical used in surface of materials or items for vacuum coating equipment, and this kind of equipment is the main feature of its internal needs to have certain vacuum environment, to have the demand of vacuum coating.
And in order to let the vacuum coating machine to achieve the effect of vacuum coating, vacuum coating machine internal process control with vacuum unit, vacuum process parameters and technological process of the automatic conversion of automatic adjustment, usually with some automatic control components, vacuum gauge, pressure control instrument and industrial automation instrument, automatic control device, automatic control system composed of microcomputer, etc. Different vacuum unit of the automatic control system, even the same type vacuum unit, for controlling the different technical requirements, the automatic control system adopted are also different. Automatic control system for vacuum device and has the relay control system, pressure control instrument or industrial automation instrument system, programmable control system, computer control system, etc. They are all so characteristics, applicable to different vacuum device control.
