The importance of degassing the vacuum coating machine workpiece What problems does the coating machine face?
What are the problems facing the development of coating machines? For the entire vacuum coating machine market, in order to achieve long-term development, each process coating technology must follow the internationalization road. It is expected that by 2015, the demand for coating machines in the coating industry will be further enhanced, and higher and higher requirements are required. Under the maintenance of traditional old-fashioned coating enterprises will face a crisis.

There have been many deep-seated problems in the entire coating machine industry market, including technical testing mechanisms, excellent corporate support policies, industrial and commercial review mechanisms and price regulation mechanisms. Some enterprises frequently have problems causing numerous complaints, such as coating machines. It is difficult for large-sized products to distinguish between good and bad. It is often to see if they can achieve the film effect they need to plate and then make a decision based on some subjective conditions.
Improve the market mechanism of vacuum coating machine, let the market decide to move, improve competitiveness, and the survival of the fittest will eventually leave high-quality suppliers, and the elimination of the numerous companies will benefit the development of the entire coating machine industry.
The upstream enterprise unit of coating machine is the accessory supplier. The core is its mature and advanced coating technology. If the inferior ordinary parts are used, the problem is easy to occur, and the service life is not guaranteed. If the vacuum is unstable, the value of the coating machine is normal. There is a leak here today, and there will be a leak tomorrow, who can stand it. A high-quality coating machine is inseparable from high-quality accessories and mature coating technology.

The importance of degassing the workpiece of vacuum coating machine
The vacuum condition is the environment that supports the operation of the vacuum coating machine, especially the equipment that requires high vacuum. Usually, the demand reaches the high vacuum. The effect of the pumping system is not enough, but in addition to the pumping system, the vacuum coating equipment In the course of operation, there is another point, that is, the degassing of the workpiece.

Some workpieces have a lot of gas, moisture, etc. inside them. These materials are discharged into the vacuum chamber when the equipment is heated, which reduces the degree of vacuum. Moreover, some gases have toxic components and directly damage the inside of the vacuum chamber. Mechanical construction, resulting in equipment not working properly. In addition, during the coating process, because the gas in the workpiece is heated and swelled, the film layer that has been plated is simply cracked. Of course, the probability of this condition is related to the physical properties of the workpiece itself, such as plastics, which are slightly swollen, and the probability It is relatively high, like a hard metal, the probability is relatively low, but it can not be ignored, so the degassing of the workpiece is very necessary.
