Vacuum plating and process flow
Source: full training update date: 216 timeing has a wide applicable scope, such as ABS, ABS + PC material, PC material products. At the same time because of its complicated technological process, environment, equipment requirement is high, the unit price are more expensive than water plating. Now: a brief introduction of the process to its product surface clean > to electrostatic >

General vacuum plating is to spray a layer of primer on the material, do the plating again. Because the material is plastic, the plastic injection when the residual air bubble, organic gases, and in place when inhaled the moisture in the air. In addition, due to the plastic surface is not smooth, direct plating surface of workpiece is not smooth, low gloss, metal feeling bad, and can appear bubbles, blisters and other adverse conditions. After spray a layer of primer, can form a smooth and flat surface, and to eliminate the inherent in plastic bubble blisters, makes the effect of the plating were
presented.
Vacuum electroplating can be divided into general vacuum electroplating, UV vacuum electroplating, vacuum plating special.
Electroplating process is relatively simple, water from the device to the environment ar
