Abstract: A method of molding PE-RT pipeline includes processes of: extrusion molding a PE-RT pipe; and injection molding a connector of the PE-RT pipe. Wherein, the process of performing extrusion molding of the PE-RT pipe is similar to an ordinary pipe extrusion molding process. The process of performing injection molding of the connector for the PE-RT pipe includes following steps: positioning, to put the PE-RT pipe around and through the core of a rotation device on a rotation disk; using the rotation device to bring the PE-RT pipe to a hot air device, to melt the connector region to a highly elastic state; bringing the PE-RT pipe into rotation to perform injection molding for the connector region of the connector; and popping out, using the rotation device to bring the PE-RT pipe into rotation counterclockwise to a pop-out device, to pop out a PE-RT pipeline.
