Polishing principle of plastic electroplating for electric heating tubes

The better the surface finish of plastic electroplated plastic parts, the better the appearance after electroplating. In general, injection molded products can also meet the requirements of the electroplating process. If the plastic surface is smooth and clean and plated without defects, it can be directly electroplated. However, due to production conditions, plastic electroplated injection molding cannot meet the requirements before plating, for example, the surface of injection molded parts is rough, foggy, frosty, binding line, mold mark Water lines, burrs, rough edges, or even inevitable scratches on the surface of some products during the production process, therefore, it is necessary to polish the surface of plastic parts to eliminate surface defects and provide lubrication and high glossiness on the plastic surface.

The most commonly used method for polishing electroplated parts before electroplating is to use a wind turbine or a general wheel cloth machine to add white wax or green wax for polishing stainless steel, which is also better for polishing. Yellow wax and red wax have a relatively poor effect. However, when polishing, it is important not to use too much force, and the power of the polishing machine should not be too high, as plastic parts with too much force can easily heat up and melt on the surface. The electroplating effect of polished plastic electroplated parts is usually very good, and the yield rate is also high.

In fact, the best solution is usually to solve it on the mold. Sometimes, the mold is used for mirror polishing or plating. The surface of the electroplated mold is very smooth, and the injection molded product can skip the polishing process and directly enter the electroplating process.
