How do you know the vacuum coating machine is good or bad

Which you can see, the development of vacuum coating technology of vacuum coating machine and vacuum coating is closely tied to the successful development of oil.
This is decided by the effect of vacuum coating of oil. In the process of vacuum coating, vacuum coating machine coating of oil to play the role of a strong bonding pieces and metal film plated (i.e., as the plating pieces of floor coating); After vacuum coating, should be coated with a layer of oil coating on the surface of the plating, then the oil and protect the metal film and dyeing effect (i.e., as a plating coating). Most of the material before a coating, must be coated with a thin layer of oil coating on the surface of the plating, thoroughly dry again after coating, otherwise, the plating on the metal film off, with the hand gently wipe away.
Vacuum coating machine is good or bad decision factors:
In the process of vacuum coating, coating quality depends greatly on the quality of the coating. Through the application of vacuum coating technology, plastic surface metallization, combine organic materials and inorganic materials, greatly improved its physical and chemical properties.
