Extrusion Screw Element
Extrusion screw elements are intermeshing components for conveying, kneading, mixing and devolatilising zones on twin-screw compounding lines. Built from imported high-hardness materials in conveying and kneading types, they are spline-tested for better matching and held in stock for regular-use brands.

Frequently Asked Questions
A screw element is an individual section of a modular twin screw that performs specific conveying, kneading, mixing, or other processing functions.
Conveying elements primarily transport material along the barrel, while kneading elements provide more intensive mixing and shearing. Different combinations can be used to build a process-specific screw configuration.
Selection depends on the polymer, filler content, additive system, required dispersion, throughput, residence time, and desired processing intensity.
Yes. ROOTIER can supply individual screw elements or complete screw assemblies according to dimensions, configuration, material, and customer requirements.
