Advantages of vacuum coating technology over traditional electroplating technology: In the past, electroplating and chemical plating were used for coating, not only the thickness is difficult to control, the uniformity of the coating is poor, the adhesion is poor, but also there are serious problems such as three wastes pollution. Today, people's awareness of environmental protection is gradually strengthened, and its development has been restricted by various aspects. The process of vacuum coating technology is simple, environmental improvement, no pollution, less consumables, even and compact film-forming, and strong adhesion with the substrate. Compared with the traditional electroplating method, vacuum coating technology has many advantages, such as good decorative effect, strong metal texture, low cost (about 1 / 3 ~ 1 / 2 of the traditional electroplating), easy operation, etc. Especially in the application of non-metallic objects, it has the incomparable advantages of traditional electroplating. In view of this, vacuum coating has been widely used in the metallization of various plastics, ceramics, glass, wax, wood and other products.





The parameter setting of the vacuum coating machine is mainly carried out on the operation panel, and the corresponding adjustment is made as the vacuum value of the vacuum chamber increases before the winding work starts.


In the main operation screen:


  "Evaporation shutdown voltage" setting key, used to set the percentage of the voltage of the evaporation boat when the winding stops, unit: %;


  "Evaporation boat voltage display", it displays the percentage of the current working voltage of the evaporation boat, unit: %;


  "Wire feeding speed display", used to display the wire feeding speed, unit:%


   (Note: The value will be automatically cleared to zero after each stop of wire feeding).


  Length meter, display the current winding length of the material, unit: m;


  "Clear" key is used to clear the display value of length;


"Initial measurement error" is when the value of "Unwinding initial diameter input" does not match the current actual unwinding diameter, and the error exceeds "Unwinding initial diameter error value positive setting" and "Unwinding initial diameter error value negative When the preset range is set between ", after the winding system starts running, this icon will flash to indicate an alarm and stop automatically. At this time, the actual roll diameter of unwinding should be re-measured and input again. Then restart the operation.


   When the "Broken Film Detection" key is enabled, it displays the current winding status of the winding system. When a film break occurs, this icon will flash to indicate an alarm, and the words "Normal" and "Broken Film" will be displayed at the same time.
