When should you replace extruder screw and barrel? Common signs include lower output, unstable extrusion pressure, poor plasticizing, higher energy consumption and excessive clearance between the screw and barrel.

As wear increases, material leakage over the screw flights reduces conveying and melting efficiency. Continuing production with a heavily worn screw barrel may increase energy costs and affect product quality.

Juyuan manufactures replacement screw and barrel sets for extrusion machines. We can produce according to your original drawing, machine model or old sample. Nitrided and bimetallic materials are available for different plastics and wear conditions.
