[0002] An extruder is also called an extruder. It is a production machine for plastic extrusion molding. The plastic extrusion of cables is generally done by extruding it with a screw through an extruder and heating it to plasticize (i.e. melt). The plastic is extruded into continuous plastic layers of various shapes required through a die and molds of different shapes, and then extruded onto the wire core and cable.

[0003] However, when the current extruder for cable production is in use, the plastic particles are not stirred during the heat melting process, and the plastic particles are piled up, which may cause them to not be completely melted, resulting in problems with the cable production quality. To address the above problems, an extruder for cable production is proposed. Utility Model Content
