The extruder can divide the machine head into a right-angle machine head, an oblique-angle machine head and the like according to the material flow direction of the machine head and the included angle of the central line of the screw. The screw extruder depends on the pressure and the shearing force generated by the rotation of the screw, so that materials can be fully plasticized and uniformly mixed and are molded through a neck mold. Plastics extruders can be largely classified into twin-screw extruders, single-screw extruders and, less frequently, multi-screw extruders and also screwless extruders.
