Brief: Discover the high-precision manufacturing process of our Customizable Twin Screw Extruder Barrel with Various Liner Alloys and Sizes. Learn how we achieve wear-resistant, corrosion-resistant, and precision-machined barrels for global export markets.
Related Product Features:
  • Customizable Twin Screw Extruder Barrel available in segmented or integral structures with screw diameters ranging from 20mm to 400mm.
  • Offers multiple liner alloy options including nitrided steel, bimetallic liners, and premium powder metallurgy alloys for enhanced wear and corrosion resistance.
  • High hardness liners reach HRC 58-65, with ZT615A alloy providing 2.5-3x the wear life of traditional tool steels.
  • Superior corrosion resistance with nickel-based liner alloys outperforming 304 and 316L stainless steel.
  • Precision CNC machining ensures strict roundness, coaxiality, and straightness tolerance control.
  • Compatible with universal parallel co-rotating extruders and customizable to match OEM interfaces.
  • Manufactured using advanced technologies like hot-press sintering, laser cladding, and cold isostatic pressing.
  • Typical applications include high-output plastic compounding, masterbatch production, and reactive extrusion processes.
Faqs:
  • Can I replace the barrel without changing the screw?
    Yes, as long as the interface and wear zones match, our barrels are compatible with your existing screws.
  • What liner alloy is best for abrasive materials?
    ZT615A or ZT818 is highly recommended due to their excellent wear and corrosion resistance.
  • How long does a barrel typically last?
    With premium alloys and standard maintenance, barrel lifespan can exceed 2-3 years in high-wear environments.
  • Can you customize for my European extruder?
    Absolutely. We have rich export experience and drawings for many EU brands (without naming them due to NDAs).
