The two-color mold technology uses multiple materials for injection molding production, and combines the characteristics of different materials during the molding process to assemble or other suitable bonding methods to improve product functionality and aesthetics. Automotive lights in two-color molds are an important application area. The features of double color car lights molds are as below: 1. The moving side of double color molds will be rotated by rotary table of double color injection machine. Hence, car lights shall be fixed on moving mold well to avoid being stuck in cavity side. 2. The fixing position after mold rotation shall be very precise, hence, the rotary table of injection machine shall be driven with servo motor instead of hydraulic motor. 3. Injecting stroke shall be designed as shorter as possible in order to enhance the strength of ejecting rod.
