1. The quality of the rough before plating should be good. Unqualified blanks are poorly plated, and plastic blanks are more difficult to inspect than metal blanks. After plating, there will be "pitting" or "star points." Therefore, we must pay attention to the quality of the blank before plating. First of all, we must understand the source of the customer's products, whether it is plated, and pay special attention to not the first batch of injection, in order to determine the quality of the blank. For the unfavorable blanks, the wheel must be polished to reach the requirements before plating. At present, most domestic manufacturers with high plating quality adopt this measure, and the pass rate of their finished products can usually reach more than 90%. Of course, rough blanks can be plated without a good product. The surface of a complete set of injection blanks is very smooth. The surface of the injection mouldings is bright as a mirror. After the plastic parts are poured out, they should be packed separately and must not collide.

2. The pre-treatment metallization plating cannot collide. Before the processing of the various parts of the plating can not be collided, especially about 70 °C erosion roughening process, ABS plastic softening increases will reduce the hardness, if the collision is very easy to rub the hair, after plating must have India. If the high-requirement plating parts, especially the relatively large or planar plating parts, are absolutely not allowed to be put into the etching liquid, the etching shall be carried out after the etching, and the product shall be mounted on a jig to be etched until electroless copper plating or no Electrolytic nickel plating.

3, plating fixtures to use reasonable. The product must not only have appropriate conductive contacts, but also have proper tightness, and must be well-conducted and clamped, but it must be prevented from being deformed due to tight clamping, especially deformation after plating. It is not enough to remove the parts without deformation after the test clamp. Must take into account the large-scale deformation after plating, in particular nickel plating higher temperature deformation. Plating jigs must be well insulated and must not be plated with particles, otherwise they will cause particle burrs on the surface of the plated parts; after the chrome plated fixture must be retired chromium layer, otherwise the copper layer is easy to become powder when the chromium layer is copper plated to form the product surface glitch.
