Why Extrusion Quality Matters?
✔ Versatile Processing
Different plastics require different screw designs. Whether you run standard PVC/PE, heat-sensitive LSZH, or high-temperature Fluoroplastics, our specialized screws ensure perfect plasticization without scorching.

✔ Concentricity Control
Our advanced self-centering crossheads and laser diameter feedback systems ensure the insulation thickness is uniform. This saves raw material costs and ensures the cable passes high-voltage tests.

✔ High Speed & Automation
With line speeds up to 500m/min (for building wire) and continuous dual-spool take-ups, our lines are built to maximize your daily output while minimizing scrap during changeovers.

The Cabletec Technical Advantage
Optimized Screw Design

Optimized Screw Design

We don't use a "one size fits all" screw. We provide BM screws for mixing, Low-Shear screws for LSHF, and Hastelloy screws for Fluoroplastics to guarantee optimal melt quality.
Precision Crossheads

Precision Crossheads

Our range includes adjustable and fixed-center crossheads with optimized flow channels. This eliminates "dead zones" where plastic can burn, ensuring long production runs without stopping for cleaning.
Intelligent Temperature Control

Intelligent Temperature Control

Using Japanese RKC or Omron PID controllers combined with air-cooling or water-cooling jackets, we maintain barrel temperatures within ±1°C, critical for sensitive materials.
Automatic Coiling Integration

Automatic Coiling Integration

Our building wire lines can be directly linked to our robotic Coiling & Packing All-in-One machines, creating a fully automated factory from conductor to finished pallet.

CLIENT FEEDBACK
What Our Clients Say
Processing Halogen-Free material was a headache until we switched to Cabletec's specialized screw design. Now we run continuous shifts without scorching issues.
Our building wire line runs at 400m/min stable. The diameter control is excellent, saving us raw material costs every day.
