Twin Screw Extruder Barrels With Integrated Wear Resistant Ralloy WR13 Alloy Steel Liner

The integrated liner is made of Ralloy WR13 high chromium powder metallurgy tool steel, featuring evenly distributed hard carbides. Combined with professional nitriding treatment, the barrel achieves outstanding wear resistance and stable anti corrosion performance when processing filled corrosive plastic raw materials.

All barrels are finished by precision CNC machining with tight tolerance control to match various imported and domestic twin screw extruder models for seamless assembly.

Covers barrel diameters from 12mm to 350mm, supporting small lab extruders medium production extruders and large scale recycling extrusion equipment.

The integrated wear resistant liner effectively reduces maintenance frequency and part replacement costs, with comprehensive service life far exceeding ordinary nitrided steel barrels.

Multiple barrel geometric structures are in stock, and customized sizes or special functional barrels can be produced according to customer drawings and production process requirements.
