Abstract

The invention provides a plastic finned tube production method. A plastic tube is extruded from an extrusion head and then enters a plastic tube circular passage of a die orifice inner sleeve body, and a plastic fin material enters from a plastic fin feeding opening and then is directly injected into a plastic finned tube body from a plastic fin extrusion molding passage to be integrally molded through a feeding groove, so that the bonding joint phenomenon caused by the production of the plastic finned tube in the prior art can be avoided, the plastic finned tube body is unnecessary to rotate, a long-distance cooling water trough is not needed for cooling, the length of a produced tube can be adjusted randomly, the production process is simple, and the product quality is greatly improved. By adopting the plastic finned tube production method, a production way of a conventional plastic finned tube is thoroughly broken through.
