In recent years, plastic decorative materials have been used in the automotive industry due to their advantages such as being environmentally friendly, aesthetic, light and economically affordable. Plastic decorative materials can exhibit high strength and metallic reflection with metal coatings. Chrome plating is generally preferred in the production of decorative plastic parts in the automotive industry. In this study, the effect of injection molding processing parameters on the metal-polymer adhesion of chrome-plated acrylonitrile butadiene styrene (ABS) was investigated. The ABS-based front grille frames are fabricated by means of using an industrial-scale injection molding machine. Then, the fabricated ABS-based front grille frame was plated with chrome by means of the electroplating method. The metal-polymer adhesion was investigated as a function of the injection molding processing parameters by means of a cross-cut test and scanning electron microscope (SEM). As a result, it was determined that the optimal injection process parameters, a cooling time of 18 s, a mold temperature of 70 °C, injection rates of 45-22-22-20-15-10 mm/s, and packing pressures of 110-100-100 bar, were effective in enhancing polymer-metal adhesion for the ABS-based front grille frame.
近年来，由于塑料装饰材料具有环保、美观、轻便且经济实惠等优点，已在汽车工业中得到应用。塑料装饰材料通过金属涂层可呈现出高强度和金属光泽。在汽车工业中，装饰性塑料部件的生产通常首选镀铬工艺。在本研究中，考察了注塑工艺参数对镀铬丙烯腈-丁二烯-苯乙烯共聚物（ABS）的金属-聚合物附着力的影响。基于ABS的前格栅框架是使用工业规模的注塑机制造的。然后，通过电镀方法对制造好的基于ABS的前格栅框架进行镀铬处理。通过划格试验和扫描电子显微镜（SEM）研究了金属-聚合物附着力与注塑工艺参数之间的关系。结果表明，最佳注塑工艺参数，即冷却时间18秒、模具温度70℃、注射速率45-22-22-20-15-10毫米/秒以及保压压力110-100-100巴，对增强基于ABS的前格栅框架的聚合物-金属附着力是有效的。
