What is two-color plastic injection mould? Two-color or two plastic materials or two components are injected on one machine, molded by two different molds, it is called two-color molding. The two-color plastic injection molds are required special design of two-color injection machine with rotary table or rotary axis, or only two injection carriage. The investment of two-color molds and two-color injection machines is higher than conventional single color molds and single color machine, however, the high quality of plastic products and precise technology on both two-color molds design and high technical adjustment of injection parameters are not easy to be copied or launched into same business.

Two-color over molding process is the lower investment for making two-color plastic products. For some bigger size two-color products or two-color plastic parts with lower market demand, it is not economic to invest two-color injection machine and two-color injection molds. Two-color over molding process is the best choice for making two-color plastic products.
