METHOD OF MOLDING PE-RT PIPELINE

摘要

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.

1. A method of molding PE-RT (polyethylene of raised temperature resistance) pipeline, comprising processes of: extrusion molding a PE-RT pipe; and injection molding a connector of the PE-RT pipe; wherein, the process of extrusion molding the PE-RT pipe includes following steps: preparing material; using an extruder to extrude into mold a PE-RT pipe; performing vacuum diameter fixing; drawing and transporting; cutting the PE-RT pipe into predetermined size to enter a positioning region; while the process of ejection molding the connector of the PE-RT pipe includes following steps: positioning, to put the PE-RT pipe around and through a core of a rotation device on a rotation disk; using the rotation device to bring the PE-RT pipe into rotation counterclockwise to a hot air device, to melt the connector region of the PE-RT pipe to a high-elastic state; performing injection molding to form the connector, to use the rotation device to bring the PE-RT pipe into rotation counterclockwise to an injection mold, then close the mold, to perform injection molding for the connector region of the connector; and popping out, to open the mold, and to use the rotation device to bring the PE-RT pipe into rotation counterclockwise to a pop-out device to pop out a PE-RT pipeline.
