Vacuum metallizing in PVD coating is used for car accessories. The technology we use is aluminum evaporation or magnetron sputtering. We can get chrome like color on plastics very fast in a metallizing machine. The raw material is usually aluminum or chrome. But protective painting is necessary for plastic items. So it's not very important to use aluminum or chrome for the metal like color. Because the layer on the top is painting. The higher vacuum we obtain during PVD coating, the colors will be more bright. And with lower vacuum when coating, the color of coatings will be more dark. Sometimes we use UV painting line for pretreatment. We need a dust free to all the machine for the complete process and we can get the best quality.
