Screw Barrel Products
Screw barrel products are machined components used in plastic extrusion and compounding machines to convey, melt, mix, homogenize, and process polymer material with optimal efficiency. The screw and barrel function in a harmonious manner to ensure that material flow, pressure, temperature, and output are all kept under control during the course of extrusion. Manufacturers can depend on quality screw barrels that are made for demanding industrial applications to enable consistent production, enhance process stability, and improve equipment performance reliability. Screw barrels are built according to machine design, the polymer type used, each production condition, and unique requirements in different diameters, configurations, as well as surface treatments with multiple materials.
Product Overview
An extrusion screw and barrel assembly is primarily a precision-molded extrusion screw and barrel, designed to work together as a matched processing system. The geometry of the screw controls the conveying, melting, mixing, and pressure-generation relationships between it and the barrel that afford a controlled processing chamber required for effective extrusion.
Screw barrel products for single-screw and twin-screw extruders can come from many different flight geometries, compression ratios, mixing sections, and processing configurations depending on the application. Dimensional consistency between the screw and barrel, which directly affects material processing and equipment performance, makes manufacturing accuracy more rigid.
Surface hardening, nitriding, bespoke alloys, and barrel linings are applied for heavy-duty applications where resistance to corrosion, abrasion, or high-temperature operating conditions is required.
