Because of its simple structure and manufacture, high processing efficiency and low price, it has been increasingly used. The screw extruder realizes solid conveying, compaction, melting and extrusion molding of materials through external power transmission and external heating elements. Wherein the heating of the cartridge wall by the external heating element effects melting of the material particles. At present, most screw extruders heat the wall surface of a machine barrel in an electric heating mode, and an electric heating coil is wound on the outer wall of the extruder, or a strip-shaped electric heating tube is paved inside the wall surface. For the first way of laying the heating coils, if the heating coils fail, all the coils need to be removed from the barrel for troubleshooting.
