Φ50mm PBT Optical Fiber Cable Extrusion Machine

The Optical Fiber Cable Extrusion Machine from Hongli represents a next-generation solution for precision sheathing and jacketing of fiber optic cables used in high-speed communications, 5G infrastructure, submarine systems, and intelligent data networks. This advanced production line is designed to deliver outstanding concentricity, thermal stability, and material compatibility, even under continuous, high-speed operation.   At the heart of the system is a high-efficiency extruder machine screw, optimized for low-shear processing of LSZH, PE, PVC, and TPU materials. This ensures consistent melt quality and precise cable outer diameters, critical for preserving fiber performance. The extrusion head is engineered to reduce eccentricity and eliminate adhesion or burn-through.   The complete Optical Fiber Cable Extrusion Line integrates:   Auto tension-controlled pay-off stand   Vacuum water calibration and U-type cooling tank   Servo-controlled haul-off and double take-up system   Intel…
