Extruder sleeve

Functions of the extruder sleeve

The extruder sleeve is a liner installed inside the barrel, surrounding the screw. Its function is to protect the barrel, withstand wear, high temperature, and high pressure, and maintain precise working clearance between the screw and the barrel.

The sleeve helps ensure stable extruder operation, optimizes the compression, cooking, and extrusion of raw materials, and extends the service life of the screw as well as the entire extrusion system

Extruder sleeve Machining at Tien Phat Mechanical Company

Manufacturing extruder sleeve is a highly technical process that requires exceptional precision, in-depth material knowledge, and extensive hands-on experience in extrusion technology. At Tien Phat Mechanical Company, high-quality alloy steel billets are carefully selected to meet stringent requirements for heat resistance, pressure endurance, and wear resistance, tailored to specific applications.

The extruder sleeve are precisely machined using CNC technology to ensure accurate design conformity, concentricity, and operational stability. Extruder sleeve surfaces undergo hardening treatments, while the heat treatment process is strictly controlled—utilizing vacuum heat treatment—to optimize mechanical properties, reduce friction, enhance wear resistance, and extend service life.

In addition, a rigorous quality control system is applied throughout the entire production process, including dimensional inspection, hardness testing, and verification of critical technical parameters, supported by advanced measuring and inspection equipment.

By combining modern machinery, advanced technology, long-standing experience, and deep understanding of real-world operating conditions, extruder sleeve manufactured by Tien Phat consistently deliver high performance, long-term durability, and stable operation in continuous production environments.

For raw materials that vary seasonally and according to customer requirements, Tien Phat provides consultation and customized extruder sleeve configuration solutions. These configurations ensure proper conveying, mixing, and cooking of materials inside the barrel, generating optimal pressure for extrusion through the die to form feed pellets tailored to specific production needs.
