Answer to Questions on PVD Vacuum Plating Process

Vacuum evaporation coating machine used in coating process quality case plastic coating process plastic vacuum coating the following problems: were scraping coating, coating peeling coating, poor quality.

This is a problem that customers encounter in vacuum coating process. From the picture, we can see that the coating is easy to fall off because it has no adhesion. There is no coating as a treatment agent on the surface before vacuum coating, which will cause this bad phenomenon. It has something to do with the material of the product. The surface adhesion of PP, pET and PE is not enough, so it is necessary to spray treatment agent to increase the surface adhesion before spraying other coatings. The coating will be strong and will not fall off. As shown below, excellent products.

Therefore, the correct vacuum coating process of PP,Pet ,PE PE plastics is to spray the treatment agent first, then the UV primer, then the evaporation coating, and finally the UV topcoat. You can get a perfect and strong coating.
