PVC toy vacuum evaporation refers to vacuum conditions

PVC toy vacuum evaporation refers to the physical heating of the evaporated metal or metal compound under vacuum conditions, so that it is solidified on the surface of PVC toys to form a uniform metal film, thereby producing the metal effect of imitation silver, imitation gold and imitation copper. Plastic coating is suitable for toys of various shapes, but the color is single, and the surface is easy to conduct. Vacuum refers to the deposit of a metal or metal compound in the form of a gas on the surface of a material (usually non-metal) in a vacuum environment. It belongs to the physical vapor deposition process. Because the coating is generally a metal film, it is also called vacuum plating, or vacuum plating (mainly to replace the traditional hydroelectric power plating). The main function of negative pressure coating is to make the surface of the coated part have high metal gloss and mirror effect, so that the coating has good barrier to the coating material, and provides excellent electromagnetic shielding and conductive effect.
