Product Description - Twin Screw Extruder Barrel by ZHITIAN
What makes a high-quality twin screw extruder barrel?

When selecting a replacement barrel for your co-rotating twin screw extruder, durability, compatibility, and customization options are key concerns. ZHITIAN's precision-engineered barrels are designed to meet the performance needs of global extrusion lines, with robust liner materials and strict dimensional tolerance control.

Key Features & Advantages
  • Custom Sizes & Interface Compatibility
    Available in a wide range of diameters and lengths, supporting modular combinations for various extruder models. Customizable inlet/outlet designs to match OEM interfaces.
  • Multiple Liner Alloy Options
    Choose from nitrided steel, bimetallic liners, and premium powder metallurgy alloys (e.g., ZT615A, ZT818) for enhanced wear and corrosion resistance. Alloys are selected based on your processing material and abrasion/corrosion load.
  • High Hardness & Wear Resistance
    Liner hardness can reach HRC 58-65 depending on the material. ZT615A alloy lining, for example, provides 2.5-3x the wear life of traditional tool steels such as M2.
  • Corrosion Resistance Beyond Stainless Steel
    Nickel-based liner alloys (e.g., ZT610, ZT615A) offer superior resistance to chemical attack, outperforming 304 and 316L stainless steel in harsh environments.
  • Precision Machining
    CNC-machined barrel body with strict roundness, coaxiality, and straightness tolerance control. Quality inspected via CMM, ultrasonic testing, and surface finish measurement.
Twin Screw Extruder Barrel Manufacturing Process - Step-by-Step Guide

At ZHITIAN, we follow a strict and traceable manufacturing workflow to ensure every twin screw extruder barrel we deliver meets the highest standards of precision, durability, and performance. Here's an overview of our barrel production process:

Step Process Description
1 Drawing Confirmation Confirm customer or internal technical drawings with specifications.
2 Production Planning Schedule machining and inspection tasks based on delivery timeline.
3 Process Design Define machining steps, tooling, and workflow.
4 Quality Control Plan (QCP) Set key control points and inspection standards for each production stage.
5 Raw Material Procurement Purchase barrel blanks according to required alloy grade.
6 Incoming Material Inspection Verify chemical composition, dimensions, and internal integrity (UT test).
7 Rough Machining Perform rough turning and milling for pre-shaping.
8 Heat Treatment (Quenching) Apply tempering/quenching to improve hardness and toughness.
9 Water Channel Machining Drill and seal cooling channels (spiral/straight).
10 Finish Machining Final bore honing, flange milling, and surface finishing.
11 Water Pressure Testing Pressure test internal cooling circuits for leakage.
12 Final Inspection Check size, hardness, tolerance, and flow. Record QC report.
13 Packaging & Shipment Anti-rust treatment, protective packing, export crate.

FAQ - Frequently Asked Questions
Q1: 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.

Q2: What liner alloy is best for abrasive materials?

ZT615A or ZT818 is highly recommended due to their excellent wear and corrosion resistance.

Q3: How long does a barrel typically last?

With premium alloys and standard maintenance, barrel lifespan can exceed 2-3 years in high-wear environments.

Q4: 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).
