Two-shot injection molding involves injecting one material into a mold to form the initial part or section of a part. Once formed, a second material is injected into the mold to form the remainder of the part.
Two-shot molding requires that the two materials be compatible (chemically similar), or no bonding occurs. Standard grades of Santoprene TPV bond to polypropylene, some polyethylenes and some TPOs. Nylon-bondable (PA series) grades bond to nylon-6 with a variety of fillers, and to some blends of nylon 6/6 (2-shot molding only). Specialty grades also exist that bond to ABS, polycarbonate, polystyrene, EPDM and metals.
