Car headlight reflector (also known as reflector) is a part of car headlight lighting system that has a reflection function to avoid direct light. It is located inside lens and decorative frame, is assembled with lens. Reflector can be seen from outside of car light through lens. Plastic parts are exterior parts with aluminum-plated surfaces. They are high-gloss electroplated parts with large-area patterns on outer surface for surface decoration. Car lights are important safety devices and decorative parts that are indispensable for automobiles. Due to high temperature working environment, reflective and light-gathering function of reflector, it is necessary to use a prefabricated monolithic molding compound (BMC) thermosetting plastic with a shrinkage rate of almost 0, heat resistance, flame retardancy, and extremely creep resistance. This material has been molded by die-casting in the past. Due to low production efficiency and high scrap rate, and because material is harmful to human body, die-casting production requires frequent manual picking and weighing of materials, which poses certain risks to health of operators. For this reason, it has become an inevitable trend to develop injection molding process of BMC materials to replace die-casting molding process.
