Single Screw Extruder Screw Barrels are designed for consistent plasticizing performance, long service life, and excellent corrosion and wear resistance. They are widely used in the extrusion of HDPE, LDPE, ABS, PP, PVC, PET, and masterbatch compounds, across industries like packaging, construction, cables, films, and profiles.

✅ Key Features:

• Materials Available:

  • 38CrMoAlA (nitrided): Surface hardness HV ≥ 900, nitriding depth 0.5–0.8mm

  • Bi-metallic alloy (Fe-based or Ni-based): Hardness HRC 58–65, lifespan 2–3× longer

• Screw diameter range: Ø16mm – Ø300mm

• Length-to-diameter ratio (L/D): 20:1 – 40:1 customizable

• Surface roughness (inner barrel): Ra ≤ 0.4μm

• Hard chrome plating & polishing options for enhanced material flow and reduced friction

🔧 Applications:
