Product Introduction
The Single screw barrel for extruder machine is a specialized core component designed to meet the processing characteristics of PE materials, including high-density PE, low-density PE, and linear low-density PE. Its primary advantage lies in enhancing material conveying efficiency and improving the uniformity of PE plasticization.
The Single screw barrel for extruder machine adopts a deep-groove, gradually varying flight design. The feeding section is equipped with deep grooves to increase material throughput, while the plasticizing section features progressively shallower grooves to enhance shear and plasticization. This design ensures complete plasticization of the PE material and stable melt flow during extrusion.
The Single screw barrel for extruder machine is manufactured from high-quality 38CrMoAlA alloy steel and treated by nitriding, providing excellent wear resistance and making it suitable for the high-speed extrusion requirements of PE materials. The inner wall of the barrel is precision-ground to achieve a high surface finish and accurate clearance with the screw, which reduces material residue and leakage while improving overall extrusion efficiency.
Different length-to-diameter ratios (L/D ratios from 25:1 to 35:1) and screw flight structures can be customized according to the production requirements of various PE products, such as pipes, films, and sheets. This component is widely used for matching and replacement in PE extruders and is suitable for equipment upgrades and routine maintenance in PE product manufacturing enterprises. It is a key component for improving production efficiency and ensuring consistent product quality in PE extrusion processes.
