Double injection molding (is also called double shot molding, two-color injection).

Double injection molding is a plastic moulding process in which two sets of moulds are simultaneously injected on the same injection machine to form one part of two different plastic materials. Sometimes the two materials are of different colors, sometimes two materials are of different hardness and softness, thus obtaining the required mechanical properties and aesthetics of the product.

The application of double-injection plastic mold and parts

The plastic parts produced though double-injection molding have been widely used in electronic products, electric tools, medical products, household appliances, toys and almost all other plastic fields. The production and molding of dual-color moulds, as well as the research and development of dual-color injection molding machines and raw materials for dual-color injection molding have also developed rapidly.

Show case of double-injection parts

Two different types of plastics are used, and the plastic products which can be clearly distinguished between the two types of plastics are called double-injection parts.
