Screw Barrel For Plastic Extruder

The Screw Barrel for a plastic extruder is a critical component, primarily constructed from highly durable materials like nitrided steel or bimetallic alloys for enhanced wear and corrosion resistance, featuring designs like single or twin (parallel or conical) screws to melt, compress and convey plastic raw materials, such as PVC, PE, and PP at precise temperatures and speeds for consistent output in the production of various products like pipes, films and profiles with typical specifications ranging in diameter and an L/D ratio of 15:1 to 40:1 depending on the specific application and polymer.
