The twin-screw extruder for cable material production heats and melts the cable material raw materials and extrude them into shape through a pair of mutually rotating screws. It is suitable for the processing needs of various cable materials. The twin-screw extruder for cable material production has a wide range of applications in the field of cable material processing. For example, it can be used to produce cable material products such as sheath materials and insulation materials.
