Co-injection molding is the term used to describe the process of feeding several melts, one after the other, into one mold during the injection molding process. The melts should make contact with each other but should not flow into one another. The resultant composites may be permanent or it may be possible to move the individual components separately. In-mold decoration and back-molding processes are sometimes also included in this category. Here, a substrate, e.g. in the form of a fabric or film, is inserted into the mold before the melt is injected in. According to this definition, co-injection molding includes the following processes:
Two-material co-injection molding / two-color co-injection molding, overmolding
