For items with large investment funds, everyone will be very cautious in purchasing, so you need to know carefully about the work you need to prepare before you buy. A vacuum coating machine is not cheap. With the booming development of the vacuum coating industry, the requirements for coatings for coatings are constantly increasing, and the range of materials used is constantly expanding. The rhythm of the product has certain challenges. Now we should pay attention to the points of vacuum coating machine / coating equipment.

First, the configuration of the vacuum system: quality and price are always proportional, no matter which process technology equipment, evaporation, ions, magnetron sputtering, the same function of the machine, with different configurations The price is definitely different. In general, 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 you look at the surface, it is basically difficult to see whether it is good or bad, can not be distinguished from the visual effect of the appearance 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 be very headache, and even indirectly some inexplicable problems, the reason for the leak is often because of 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 of different processes is not the same. The following is called the evaporation source, which may be a target or an 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 improved after continuous collection of coating data for many years. 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, sample proofing: Before taking the vacuum coating machine/coating equipment, take the sample to remove the coating, check whether the coated film can meet its own requirements, whether its technical service and after-sales service are perfect. Shop around.
