An extruder overhaul is more than simply replacing worn or damaged parts. It is a comprehensive preventive maintenance service that restores equipment performance and ensures reliable, efficient operation.

Our overhaul process includes screw and barrel wear inspection, gearbox and drive system maintenance, precise temperature and pressure control verification, and the replacement of critical components as required. These services help stabilize product quality, improve energy efficiency, and prevent unexpected equipment failures.

With extensive experience in extrusion technology, SINKHAN MACHINE provides professional overhaul solutions that maximize equipment reliability, extend service life, reduce maintenance costs, and enhance long-term productivity.
