Plastic extruders also belong toplastic machineryOne of the types. The extruder is based on the direction of the material flow at the head andthreaded rodThe angle of the centerline can be used to divide the nose into right angled nose and angled nose, etc. The outer shell of the machine head is usually made ofboltFix it on the fuselage, the mold inside the nose contains a mold core seat, and then usenutFix it at the inlet port of the machine head, and the interior of the mold core seat is also equipped withCoreAnd there are holes in the center of both the mold core and the mold core seat, which are used to pass through the core wire. According to the different types of pressurization methods, the extrusion process can be divided into two types: continuous extrusion and intermittent extrusion. The former uses a screw extruder, while the latter uses a plunger extruder. Here, screw extruders can be roughly classified into single screw extruders and multi screw extruders based on the number of screws.
