In the plastic extrusion industry, the extruder conical twin screw barrel is a core component that directly impacts the efficiency, precision, and durability of your extrusion process. Whether you’re manufacturing PVC pipes, profiles, or WPC panels, a high-quality conical barrel ensures excellent material melting, stable output, and long equipment life.
If you’re looking for a cost-effective and reliable supplier, China has become the go-to source for conical twin screw barrels trusted by global OEMs and plastic manufacturers.
🔍 What Is an Extruder Conical Twin Screw Barrel?
A conical twin screw barrel features two intermeshing, tapered screws rotating inside a specially shaped barrel. Unlike parallel barrels, the screw diameter gradually decreases from the feed section to the discharge section, providing:
- Higher torque transmission
- Better sealing at the output end
- Improved shearing and plasticizing performance
- Compact barrel length for limited space installations
🧰 Applications of Conical Twin Screw Extruders
These systems are widely used for:
- PVC pipe extrusion (U-PVC / C-PVC)
- PVC profile extrusion (window frames, doors, skirting boards)
- WPC (Wood-Plastic Composite) production
- Cable trunking and panel manufacturing
Their precision design allows for stable production of both rigid and soft PVC formulations under various pressure and temperature settings.
