Vacuum plating concept

Vacuum plating including: vacuum deposition, sputtering and ion plating types. They are used in vacuum conditions, by distillation or sputtering, etc. deposited on the surface in the plastic films of metal and non-metallic, can be obtained by this way a very thin surface coating, but also has good adhesion projecting speed advantages, but the price is higher, you can operate fewer types of metal, usually used for higher-end products, functional coatings, such as an internal shield use. Common plastic products plating process in two ways: water plating and vacuum ion plating.Vacuum ion plating, also known as vacuum coating, vacuum plating practice is now a more popular approach, products made out of metal feeling, high brightness, while relative to other coating method, the cost is low, the environmental pollution small, is now widely used in various industries.
Vacuum plating broader scope of application materials such as ABS, ABS + PC material, PC material products. While its complex process, environment, equipment requirements, price expensive than water plating. Present a brief introduction to its process: Product Surface cleaning -> destaticizing -> spray primer -> baking primer -> Vacuum Coating -> spray paint -> baking finish -> packaging.
General practice is to vacuum plating material on the first layer of primer spray, do plating. Since the Molybdenum tube is plastic parts, injection molding will be left in the air bubbles, organic gases, and in the place when moisture in the air will be sucked addition, As the plastic surface is not smooth, direct plating of the workpiece surface is not smooth, low gloss, metallic feeling bad, and there will be bubbles, blisters and other adverse conditions. sprayed layer of primer after the formation of a smooth surface, and put an end to plastic blister bubble inherent generation, making the plating effect can be demonstrated.
Vacuum plating can be divided into general vacuum plating, UV vacuum plating, vacuum plating special. Processes are evaporation, sputtering, gun color and so on.
Application examples: PC material temperature of 130 degrees, only the "vacuum plating + UV shiny solid" can reach 130 degrees high temperature resistance requirements. And general water plating material can not be carried out on the PC plating! Some time ago, Shenzhen Ji Industrial Co., Ltd. announced that the company out of the effect of UV vacuum coating can reach 300 plated.
