Electroplating PC/ABS plastic products are widely used in cars, household appliances and IT fields with their bright metallic appearance. The design scheme of raw material secret recipes and electroplating processing technology are generally key elements that people think are harmful to PC/ABS electroplating performance. However, few people are concerned about the harm of the molding process to electroplating performance.

Injection molding temperature

     While ensuring that the raw materials are not prone to cracking, higher injection molding temperatures can achieve stronger electroplating performance.

     At a lower injection molding temperature, the flowability of PC/ABS materials is poor, and the injection molded products have great internal stress. The stress is released during the passivation process, resulting in uneven ion implantation on the surface of the product, resulting in poor appearance of the electroplating product and poor electroplating bonding.

    Higher injection molding temperature can reduce the residual internal stress of the product, thereby improving the electroplating performance of the raw materials. Relevant studies show that compared with products with injection molding temperatures of 230℃, when the temperature is increased to 260℃-270℃, the coating bondability is increased by about 50%, and the surface appearance failure rate is also greatly reduced.

Little do they know that the injection molding temperature should not be too high. If the cracking temperature of the raw material is exceeded, it may cause the surface of the injection molding product to be poor, thereby endangering its electroplating performance.
