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.
Zhitian has developed its own range of high-performance alloy materials for extruder barrels, optimized for superior wear and corrosion resistance. The company is equipped with advanced production equipment including cold isostatic pressing, vacuum hot-press sintering furnaces, and laser cladding systems. All machining is carried out in temperature-controlled workshops to ensure high precision, enabling us to control key dimensional tolerances of extruder barrels within 0.01 mm.
Zhitian’s ZT Series high-performance alloys include:
These alloys are manufactured using different technologies:
With strong project management capabilities and years of export experience, Zhitian ensures not only premium materials but also consistent quality and performance for twin screw extruder barrel applications.
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. |
Typical Applications
| Parameter | Range / Option |
|---|---|
| Screw Diameter Range | 20mm - 400mm |
| Liner Materials | Nitrided steel, Bimetallic, ZT615A, etc. |
| Barrel Structure | Single or multi-piece, closed/open |
| Tolerance | ≤ 0.02mm |
| Heat Treatment | Gas nitriding, Vacuum quenching |
| Surface Hardness | HRC 58-65 (liner) |
Yes. As long as the interface and wear zones match, our barrels are compatible with your existing screws.
ZT615A or ZT818 is highly recommended due to their excellent wear and corrosion resistance.
With premium alloys and standard maintenance, barrel lifespan can exceed 2-3 years in high-wear environments.
Absolutely. We have rich export experience and drawings for many EU brands (without naming them due to NDAs).
