Teflon High-Temperature Extrusion Line
Fluoropolymer Insulation Line Running to 500 Degrees Celsius
Product Overview
What This Product Is
This line insulates wire with fluoropolymers — FEP, PFA, ETFE and PTFE by paste extrusion — for aerospace, military, medical and high-end industrial cable. The extruder barrel and screw are specially treated for fluoropolymer resistance and run continuously up to 450–500°C, with a 600°C die zone. Laser diameter control with closed-loop feedback keeps insulation thickness consistent, and a cleanroom option is available for medical-grade FEP tubing.

Key Benefits
What It Gives Your Production Line
Built for Corrosive High Temperature Work
Barrel, screw and components are treated and corrosion resistant for aggressive fluoropolymers at 500°C.
Concentric Insulation on Fine Wire
A precision crosshead die plus laser gauge with closed-loop feedback holds thickness to fine tolerance.
Servo Driven Line Control
Servo-motor capstan and PLC with HMI keep line speed and tension synchronised through the process.
Cleanroom Option Available
For medical-grade FEP tubing and ultra-clean insulation production.
Application Scenarios
Where It Is Used
- Aerospace and military wiring harnesses
- Medical tubing such as catheters and probes
- High-temperature sensor wires

Problems It Solves
The Reasons Buyers Move To This Product
Standard Extruders Fail on Fluoropolymer
Ordinary barrels corrode and cannot hold 500°C. This line is specified for the material from the start.
Thermal Stress Cracks the Insulation
Multi-section cooling reduces temperature gradually so internal stress does not build up.
Medical Work Demands Clean Production
The cleanroom option addresses contamination control for medical tubing.

Use Guide
Working With It On Your Line
- Extract and ventilate the die area properly — fluoropolymer processing releases fumes at these temperatures.
- Preheat the conductor to drive off moisture or the insulation will show voids.
- Bring the barrel to temperature slowly to protect the treated surfaces.
- Use the laser gauge feedback rather than periodic sampling to hold insulation thickness.
