Abstract: Various embodiments of a process for making hollow thermoplastic articles (180) are provided. In one embodiment, a process for producing hollow thermoplastic article (180) includes placing a sock preform (111, 113, 115, 117) of a first polymer composition about a core pin (110, 112, 114, 116) and injection molding a molten parison of a second polymer composition that is different than the first polymer composition into an injection mold cavity (150, 152, 154, 156) and onto the sock perform. The injection molding process produces an injection preform having two different material compositions. The process further include blow molding the injection preform to produce a hollow thermoplastic article having an interior surface of the first polymer composition and an exterior surface of the second polymer composition.
