Plastic pipe structures are typically injection molded using a mold using an injection molding machine. The mold comprises a mold body and a core mounted therein. Take a pipe fitting in a buried Polyethylene (PE) pipeline as an example: the polyethylene pipe fitting structure comprises a straight-through, an elbow and a tee. The PE pipe fitting structure product has the characteristics of large wall thickness and long forming period. The molding cycle of the current single PE pipe structure product reaches 40-50 minutes, which is hard to imagine in other injection molding industries.

Accordingly, there is a need in the industry to develop an apparatus or structure that can be used to produce tubing in a highly efficient manner and in an automated fashion.
