Automotive Wire Extrusion Lines

The Automotive Wire Extrusion Line is engineered specifically for the high-speed insulation of automotive wires, a product segment defined by tight dimensional tolerances, demanding material performance requirements, and the high production volumes that characterize the automotive supply chain. Every meter of wire leaving this line must meet consistent wall thickness, concentricity, and surface quality standards — deviations that are acceptable in lower-grade wire production are not tolerated in components destined for vehicle electrical systems. The line is designed for sustained operation at high linear speeds, with a screw and barrel configuration optimized for the rapid, stable plasticization of automotive wire insulation compounds. Applicable materials include PVC, PE, XLPE, PU, and other specialty thermoplastic compounds used across the full range of automotive wire types — from low-voltage body harness wire to battery interconnect cables for electric vehicles. Material changeover is straightforward, enabling manufacturers to run multiple compound types on the same line without extensive cleaning downtime. Precision closed-loop diameter measurement and automatic cross-head adjustment are integrated into the line control system, allowing real-time correction of wall thickness deviations before they generate out-of-specification product. Spark testing is incorporated inline to catch any insulation defects immediately, ensuring that every coil dispatched to the harness assembly operation meets electrical integrity requirements. The capstan and take-up system is engineered for consistent tension control at high speeds, preventing conductor deformation and ensuring that dimensional specifications are maintained from the start to the end of every production reel. The overall line layout is designed to minimize footprint while maintaining full accessibility for maintenance and die change operations. This extrusion line is suitable for Tier 1 and Tier 2 automotive wire suppliers producing harness wire, sensor cables, and EV battery cables to JASO, ISO, and OEM-specific standards.
