This conical twin-screw barrel is a core component specifically developed for plastic extrusion molding processes, widely adaptable to various scenarios such as PVC granulation, pipe extrusion, profile production, and sheet processing. The product uses high-quality 38CrMoAlA base material, with the screw edges reinforced using a dual-alloy spray welding process. The barrel inlet area can be made of high-quality alloy steel to ensure stable operation under high load and high wear conditions. Core specifications cover the entire range from Ф35/Ф75 to Ф135/Ф270, and the compression ratio can be precisely customized according to different raw material characteristics. It can adapt to diverse processing needs, from conventional PVC powder to materials with high calcium content. Combined with a precise temperature control system, it achieves efficient plasticization and uniform extrusion of materials.
