We often come into contact with such customers. We know what materials our products need to be coated with, and also know that we need to coat the materials, and we need to purchase a pvd coating machine. However, we do not know what pvd coating machine we want to purchase, nor how to purchase a pvd coating machine suitable for our company

We often come into contact with such customers. We know what materials our products need to be coated with, and also know that we need to coat the materials with a film, and we need to purchase a pvd coating machine. However, we do not know what pvd coating machine we want to purchase, nor how to purchase a pvd coating machine suitable for our company. At present, the pvd coating machine is used to evaporate metal film, colorful film, gold imitation film, etc. on the surface of optical, glasses, plastic film, metal, lamps, ceramics, glass and other products, so as to obtain bright, beautiful, cheap plastic, ceramic and other surface metallized products. It is widely used in the surface metallization coating of various plastic toys, plastic daily decorations, artificial jewelry, Christmas decorations, home appliance decorations, electrical instruments, decorations and lamps. Since the pvd coating machine is so widely used, how can we purchase a suitable pvd coating machine?
1、 Choose the type of pvd coating machine according to the material of the workpiece to be coated and the effect of plating. For example, if we are mainly engaged in fine processing, we will buy vacuum aluminized mirror making machine; If we are engaged in plastic coating, for example, in the automotive lampshade industry, we should choose a circular vertical pvd coating machine.
2、 Various process parameters that can be reached by the pvd coating machine should be considered, such as coating color, roughness, adhesion, etc.
3、 The electrical conditions of the equipment shall be considered. The power consumption shall be considered according to the configuration. Otherwise, the power problem cannot be solved, and the equipment cannot be used after purchase.
4、 It is necessary to consider the capacity and quality of vacuum coating to select a suitable pvd coating machine. If the output is too small, the price will be high. On the other hand, overcapacity will cause waste of resources. And the equipment is too large for all products.
5、 Site issues. It is necessary to buy a pvd coating machine of different specifications according to the requirements to consider how large the area of equipment needs to be installed.
6、 Does the manufacturer of pvd coating machine support the technology? Is there maintenance service? It is better to ask the vacuum coater manufacturer to recommend the manufacturer who has purchased the coater and ask about the quality and service of the coater manufacturer.
7、 The characteristics of medium and high-end equipment must be stable, and the selected parts must be reliable. The coating machine itself is a complex system, including vacuum, automation, machinery and other systems. The unreliability of any component will cause instability of the system, which will bring inconvenience to production. Therefore, a stable equipment should ensure that every component selected is reliable. Many people buy the coating machine, It is natural to compare the basic configurations of a 1 million yuan coating machine and a 2 million yuan coating machine. However, it is the mastery of some small details that makes a stable coating machine.
8、 To see which company's coating machine is used by well-known companies in the industry, this is undoubtedly the least risky choice. Famous companies include large companies such as Foxconn, Zhongnan, BYD, and Senfeng, as well as some small and medium-sized companies with very stable quality and good reputation. Through friends, you can find out which company's equipment they are using. If you want to compete with these companies, It is basic to choose a coating machine that is at least as good as others, and then hire an experienced coating master, so that your product will soon open up a market.
9、 At present, there are basically two kinds of vacuum pumping systems, one is diffusion pump system, the other is molecular pump system. The molecular pump system belongs to a clean air pumping system. There is no oil return phenomenon of diffusion pump, the pumping speed is relatively stable, and the power consumption is relatively low. The cost of electricity is a large part of the production and operation costs of coating enterprises. The regular maintenance of the pump system is very important, especially the regular replacement of the lubricating oil. Pay attention to the selection of the oil brand. The vacuum pump is easily damaged if the selection is wrong.
10、 At present, the vacuum detection system basically uses a combination of composite vacuum gauge, thermocouple gauge and ionization gauge. In the process of filling a large amount of gas containing C, the ionization gauge is easy to be poisoned, causing damage to the ionization gauge. If the process of plating gas containing a large amount of C, it can be considered to configure a capacitive film gauge.
11、 For vacuum power supply, the gap between domestic power supply and imported power supply is still obvious. Of course, the price is also relatively favorable. A domestic 20KW medium frequency power supply is about 80000, and an imported medium frequency power supply is 200000. The performance, reliability and stability of imported power supply will be better. Since the domestic power supply is produced in China, it may be better than imported power supply in terms of service.
12、 Control system. Many pvd coating machines now use full automatic control, but there is still a big difference in automatic control. Most of them are in semi-automatic state, and can really achieve full automatic control. There are not many pvd coating machines with one key operation. In addition, there is a big difference in functional modules whether there is enough safety interlock in operation in automatic control.
13、 Whether the low-temperature catcher PolyCold is required? It can be said that the low-temperature catcher is a kind of icing on the cake equipment. It can greatly improve the air extraction speed, adsorb the condensable gas in the vacuum chamber on the cold coil, purify the atmosphere in the vacuum chamber, and make the film quality better. In hot and humid summer, the use of the low-temperature catcher undoubtedly improves the production efficiency to a large extent.
