Extruder (Extruder) is mainly a machine used to produce plastic products such as wires and cables, pipes and profiles. It can melt, plasticize and mix the plastics through the pressure and heat generated by the rotation of the screw, and then extrude the plastics into the required shape through a specific mold. Extruders are widely used in the production of wires and cables, tubes, profiles, sheets, films and other fields.
In the wire and cable industry, the extruder is mainly used to produce the insulation layer and sheath layer of wire and cable. By melting and plasticizing the plastic material and then extruding it onto the wire conductor to form an insulating layer or sheath layer, it serves to protect the wire conductor and transmit current.
The main components of the extruder include screw, barrel, mold, heating system, transmission system and control system. Among them, the screw is the core component of the extruder, which is responsible for pushing the plastic material forward and generating pressure and heat to melt and plasticize the plastic. The barrel is the part that loads the plastic material, and the die is the part that extrudes the plasticized plastic into the desired shape. The heating system is used to provide the heat needed to melt the plastic, the drive system is responsible for the rotation of the screw, and the control system is used to control the operation of the entire extruder.
