Screw Barrel For Twin Screw Extruder

The Screw Barrel for a Twin Screw Extruder is the core processing component, consisting of two intermeshing screws, typically modular and mounted on splined shafts, operating within a precision-bored, often sectional, heated barrel. These crucial parts are engineered from high-wear and corrosion-resistant materials, such as nitrided steel or bimetallic alloys, with diameters commonly ranging from 20 mm to 250 mm and customizable lengths, with an L/D ratio up to 40:1, to efficiently convey, melt, mix, and homogenize materials like plastics, masterbatches, and compounds for applications such as PVC pipe, profile extrusion, and compounding.
