What are the main features of the vacuum coating machine?

 

1. The vacuum system is well configured, using PLC control, and the pumping speed is relatively fast;

 

2. Equipped with high-power power supply, the film uniformity is good, and the coating efficiency of the winding coating machine is high.

 

3. Tension control adopts imported digital control system, which has the characteristics of tension, rapid movement and constant line speed;

 

4. The wire feeding of each group is mainly controlled independently by the microcomputer motor, which can be adjusted in general or individually, and has a speed display;

 

5. The winding equipment system uses high-precision tributaries or AC frequency conversion for speed regulation, which has the characteristics of high speed and stable operation, no scratches on the original coil, neat winding end faces and no wrinkles.

Electroplating Physical Deposition Phenomenon of Vacuum Coater

 

Vacuum plating is a physical deposition phenomenon. That is, argon gas is injected in a vacuum state, and the argon gas hits the target material, and the target material is separated into molecules that are adsorbed by conductive goods to form a uniform and smooth surface layer. In order to meet the requirements of safety, energy saving, noise reduction and pollutant emission reduction, vacuum electroplating has become a new trend of environmental protection in the surface treatment process. Different from general electroplating, vacuum electroplating is more environmentally friendly. At the same time, vacuum electroplating can produce a black effect with good gloss that cannot be achieved by ordinary electroplating.

Maintenance of vacuum coating machine

 

1. It is necessary to test the proportion of gas sealing performance in the vacuum chamber to ensure that the air tightness can meet the requirements.

 

2. Then check the size, shape and air leakage speed of the vacuum coating leak, analyze the solution and implement it.

 

3. It is necessary to admit that the gas leakage of vacuum electroplating is a real leakage or a false leakage. Since a certain amount of gas will be generated to varying degrees after the workpiece material is heated, sometimes it is mistaken for the gas flowing in from the outside, which is a false leakage. Let's rule this out.

 

4. Confirm the small leak detection rate and leak detection sensitivity of the detection instrument, detect air leakage in a large range, prevent some leaks from being neglected, and improve the accuracy of leak detection.

 

5. It is also necessary to prevent the blockage of the leakage holes of vacuum plating. Sometimes due to operational errors, there will be some dust or liquids that block the leakage holes during the vacuum plating process. Due to the difference in internal and external pressure, the leakage may not be blocked, but the leakage will still exist.
