Technical Specifications

Designed for Professional PVC Pipe Manufacturing

Modern PVC pipe production requires precise control over temperature, pressure, material feeding, and melt quality. The EXTRUTEX EXC 80 has been specifically designed to deliver consistent performance during continuous production while maintaining outstanding product quality.

Its advanced conical twin screw design provides progressive compression of PVC material throughout the extrusion process. This controlled compression improves plasticization efficiency while reducing unnecessary shear stress, minimizing material degradation and producing pipes with smooth surfaces and excellent mechanical properties.

Whether manufacturing municipal water pipes, industrial pressure pipes, or C-PVC pipes for high-temperature applications, the EXC 80 maintains stable processing conditions throughout extended production cycles.

Advanced Conical Twin Screw Technology

The core of the EXTRUTEX EXC 80 is its precision-engineered conical twin screw system.

Compared with conventional parallel twin screw designs, the conical configuration provides significant advantages for PVC processing.

• Improved material intake
• Higher filling efficiency
• Excellent melt homogenization
• Stable extrusion pressure
• Lower specific energy consumption
• Reduced material degradation
• Extended screw & barrel service life

The optimized screw geometry ensures smooth transportation of PVC powder from feeding to final melt formation while maintaining accurate temperature control throughout the entire processing cycle.

Powerful 55 kW Drive System

Production efficiency depends on both output performance and energy consumption. The EXTRUTEX EXC 80 is equipped with a high-efficiency 55 kW motor designed to deliver consistent torque for demanding industrial production.
