It is very necessary to degas the workpiece of the vacuum coating machine

Some workpieces have a lot of gas, moisture, etc. in themselves. These substances will be discharged into the vacuum chamber when the equipment is heated, reducing the vacuum degree. What's more, some gases have toxic components, which directly damage the vacuum chamber. The internal mechanical structure causes the equipment to not function properly.

In addition, during the coating process, due to the heating and expansion of the gas in the workpiece, it is easy to crack the coated film. Of course, the probability of this situation depends on the physical properties of the workpiece itself, such as plastics that are easy to expand, the probability is relatively high. For hard materials such as metal, the probability is relatively low, but it cannot be ignored, so the degassing of the workpiece is very necessary.

The main components of the chiller dedicated to the vacuum coating machine are:

The main components of the chiller for vacuum electroplating equipment are: compressor, liquid receiver, filter drier, thermal expansion valve, evaporator, refrigerant, and condenser. The compressor is the heart. The chiller refrigeration system inputs electrical energy through the compressor, and discharges the heat from the low temperature environment to the high temperature environment. The refrigeration compressor determines the efficiency of the entire system. The liquid accumulator is installed behind the condenser and is directly connected to the drain pipe of the condenser. The liquid accumulator plays the role of adjusting and storing the refrigerant.
