JSK FACTORY DIRECT
Key Engineering Advantages
- Nitrided 38CrMoAlA alloy steel screw & barrel with bi-metallic wear coating for 5x service life
- Precision multi-zone PID heating/cooling system with cast bronze ceramic elements and quiet air blowers
- Self-centering precision crosshead tooling for sub-micron concentricity and uniform wall thickness
- Synchronized line control with dual-axis laser diameter gauge and automatic closed-loop feedback
- High-efficiency multi-pass stainless steel cooling trough with temperature tempering and air wipes
Overview & Applications
JSK MACHINES manufactures state-of-the-art continuous cable extrusion lines designed for high-speed primary wire insulation, inner sheathing, beddings, and outer protective jacketing. Engineered to process a wide spectrum of polymers including PVC, XLPE, LDPE, HDPE, LSFH (Low Smoke Zero Halogen), Nylon, and elastomer rubber compounds.
The entire line integrates a driven payload pay-off, dancer tension regulator, high-efficiency extruder extruder head, stainless steel cooling trough, non-contact laser diameter monitor, caterpillar haul-off capstan, spark tester, and dual automatic take-up spoolers.
Integrated PLC automation with touchscreen HMI gives complete recipe storage, automatic line ramp-up synchronization, and melt pressure monitoring for 100% defect-free cable output.
