In the plastic extrusion molding equipment, the plastic extruder is usually called the main machine, and the subsequent equipment that is matched with the plastic extrusion molding machine is called the auxiliary machine. After more than 100 years of development, plastic extruders have derived from the original single-screw, twin-screw, multi-screw, and even non-screw models. The plastic extruder (host) can be used with a variety of plastic molding auxiliary machines such as pipes, films, holding materials, monofilaments, flat wires, packing belts, extruded nets, plate (sheet) materials, profiled materials, pelletizing, cable coating, etc. Match to form a variety of plastic extrusion molding production lines to produce a variety of plastic products. Therefore, plastic extrusion molding machinery is one of the models used in the plastic processing industry no matter now or in the future.

The main engine of the plastic extruder is an extruder, which is composed of an extrusion system, a transmission system and a heating and cooling system. The extrusion system includes screw, barrel, hopper, head, and die. The plastic is plasticized into a uniform melt through the extrusion system, and under the pressure established in the process, it is continuously extruded by the screw head.
