Built for PVC insulation
in wire & cable production
The JP-SE Series is purpose-built for PVC insulation applications in the wire and cable industry. Its specially designed screw geometry ensures gentle, low-shear processing of PVC compound — preserving thermal stability and delivering consistent melt quality at the crosshead die with no scorching or degradation.
Available in screw diameters from 50mm to 90mm with a uniform 26:1 L/D ratio, the JP-SE is sized for all wire gauges, from fine automotive wiring harnesses to heavy power cable insulation. Each unit ships as a complete, pre-commissioned system with drive, digital temperature controllers, and crosshead die-head connection ready to integrate with your existing line.
Key Features
- Purpose-designed PVC screw geometry — low-shear processing prevents compound degradation and discoloration
- Nitrided barrel with 4–6 independent temperature zones (±1°C stability) optimized for the PVC processing window
- Variable-speed AC drive with precise speed control — consistent insulation wall thickness at all line speeds
- Digital PID temperature controller for each zone — safeguards PVC against thermal degradation
- Melt pressure & temperature monitoring at the crosshead for real-time insulation quality control
- Compatible with crosshead dies for round and sector conductors — insulation and sheathing applications
