At present, the number of domestic vacuum coating equipment manufacturers is increasing, there are hundreds of domestic and many foreign countries, so how to choose a suitable supplier among so many brands? How to choose the right vacuum coating equipment manufacturer for yourself? This depends on identification by yourself, now I come with you to identify the real suitable vacuum coating equipment suppliers.
Product positioning
To determine the level of vacuum coating equipment manufacturers according to your product positioning, if your product positioning in the high-end market, then you must choose the high-end equipment, and vice versa, select or low-end, of course, if sufficient funds, to buy a high-end, richer performance, more stable quality of equipment is the best.
Pursuing product stability
The characteristics of high-end equipment, equipment stability must be good, the choice of parts must be reliable, the coating machine is a complex system, including vacuum, automation, mechanical and other systems, the unreliability of any one component will cause system instability, will bring inconvenience to the production, so a stable equipment need to ensure that the choice of each component is reliable. When many people purchasing a coating machine, it is natural to compare a 1 million dollar coater with a 2 million dollar coater in terms of basic configuration, but it is the mastery of some details that makes a stable performance coater.
Market research
Look at the well-known companies in the same industry are using which company’s vacuum coating equipment, which is undoubtedly the least risky way to choose. From the direction of electricity cost and equipment maintenance, there are basically two kinds of vacuum pumping systems, one is the diffusion pump system and the other is the molecular pump system. Molecular pump system is a clean pumping system, no diffusion pump oil return phenomenon, pumping speed is relatively stable, and more power-saving, electricity expenses are a big part of the production and operation costs of coating enterprises. Regular maintenance of the pump system is very important, especially the regular replacement of lubricating oil, pay attention to the choice of oil brand number, the wrong choice is easy to damage the vacuum pump.
Vacuum testing system
At present, basically use the combination of compound vacuum gauge, thermocouple gauge + ionization gauge, this combination is encountered process of charging a large number of gases containing element C, ionization gauge is easy to poison, resulting in damage to the ionization gauge, if the coating process with a large number of gases containing element C, you can consider configure capacitive film gauge.
Vacuum power supply
Domestic power supply and imported power supply gap is still relatively obvious. Of course, the price is more favorable, a domestic 20KW IF power supply in about 80,000 CNY, an imported IF power supply in 200,000 CNY. Imported power supply performance and reliability, stability will be better. Due to domestic power supply is originated in the home, may be better in service than imported power supply.
Now, control system of many the coating machine are fully automatic control, but the difference in the automatic control is still very large. Most of it is in the semi-automatic, which can really realize the fully automatic control and one key operation of the coating equipment is not much. And whether the automatic control gives enough safety interlock in the operation, the functional module is also a big difference.
Low temperature trap PolyCold
Whether you need to configure the low temperature trap PolyCold? Low temperature trap can be described as a kind of icing on the cake, it can greatly improve the speed of pumping. The condensable gas in the vacuum chamber adsorbed on the cold coil, purify the air in the vacuum chamber, so that the quality of the film layer is better, in the hot and humid summer, the use of low temperature trap undoubtedly improves productivity to a large extent.
Cooling water recycling system
The coating machine needs to be equipped with cooling water circulation system, cooling water is best to use deionized water, which has a great effect on anti-corrosion, especially the welding channel of the vacuum chamber, some of the parts that are easy to rust, etc. have a good inhibiting effect. You can add some antiseptic to the deionized water, which can also prevent corrosion.
