What should I pay attention to when purchasing vacuum coating machine equipment?

For items with large investment funds, we will be very cautious when purchasing. We must understand the work we need to do before purchasing. A vacuum coating machine is not cheap. With the rapid development of the vacuum coating industry, The requirements for the film layer of the product to be coated are also gradually increasing, and the range of materials used is gradually expanding, which is a challenge for the vacuum coating machine to keep up with the product rhythm. Now let's introduce some points to pay attention to when purchasing a vacuum coating machine.

First, the configuration of the vacuum system: quality and price are always proportional, regardless of the process technology equipment purchased, evaporation, ions, magnetron sputtering, the same function of the machine, have different Configuration, the price is definitely different. Generally speaking, the configuration means that the materials used are good, the natural service life will be longer, the efficiency will be higher, and the film formation is better.

Second, the vacuum coating machine shell: If it is from the surface, it is basically difficult to see whether it is good or bad, can not be distinguished from the visual effect of the surface alone, the shell can basically be processed by each vacuum equipment manufacturer. For the shell should focus on the sealing, welding is very important, if the machine equipment is bought back to find the problem of air leakage, then the customer will have a headache, and even indirectly some inexplicable problems, the reason for the leak is often due to processing not good. Therefore, customers must pay attention to processing strength when choosing to purchase vacuum coating machine/coating equipment.

Third, the core of the process: the core used in different processes is not the same, unified as the evaporation source, it can be the target or electron gun. If you don't have a good evaporation source, basically don't want to finish a stable high quality coating. A good evaporation source needs to be improved and perfected after years of continuous coating data. It is difficult for manufacturers who do not understand the process to do the evaporation source. If you say that the machine does not contain the process, you must not buy it.

4. Field inspection and sample proofing: Before purchasing a vacuum coating machine or coating equipment, take the sample to remove the coating, check whether the coated film can meet its own requirements, and whether its technical service and after-sales service are perfect, combined with the above The main points of the consultation are more than three.
