Vacuum plating and process
Source: the full update training date: 2011 09 month tion, such as ABS, ABS+PC material, PC material products. At the same time because of its complex process, environment and equipment requirement is high, the price of water than electroplating expensive. This article provides a brief introduction to the process of product surface cleaning 一 "to" - "一 electrostatic primer spray baking primer. Vacuum coating, spray paint, baking finish packing. 一一
The general practice is in the vacuum plating material to spray a layer of primer, and then electroplating. Because the material is plastic, residual air bubbles, the injection of organic gases, and when placed in the inhalation of moisture in the air. In addition, because the plastic surface is not smooth, direct plating of the workpiece surface is not smooth. Low gloss, poor sense of metal, and the bubble will appear, blisters and other adverse conditions. After spraying a layer of primer, will form a smooth surface, and prevent plastic itself bubble blisters, the plating effect can be demonstrated.
Vacuum plating can be divided into general vacuum plating, vacuum plating, vacuum plating UV special. Process of evaporation, sputtering, gun color.
For the hydropower plating process is relatively simple, from the equipment to the environmental requirements are not st
