Cable Sheathing Machine

The Cable Sheathing Machine is specialized equipment designed specifically for processing PVC cable sheaths. Its core advantage is its ability to accommodate the unique processing characteristics of PVC, ensuring that the finished sheath exhibits excellent flexibility, wear resistance, and weather resistance.

The Cable Sheathing Machine features a low-shear flight design combined with an optimized length-to-diameter ratio, achieving uniform plasticization of the PVC material while preventing degradation caused by shear overheating. This preserves the mechanical properties of the sheath and ensures consistent quality. The barrel employs a zoned heating and forced cooling system, providing precise temperature control to maintain optimal plasticization conditions throughout the extrusion process.

The extruder head uses a dedicated sheath extrusion design with an optimized flow channel, ensuring that the PVC melt uniformly coats the cable core. This results in a smooth surface and consistent sheath thickness. The equipment is equipped with a precise traction and winding system that operates in synchronization with the extrusion process, enabling continuous, high-quality production.
