Premium Features & Benefits
- 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.
- High Hardness & Wear Resistance: Liner hardness can reach HRC 58-65 depending on the material. ZT615A alloy lining provides 2.5-3x the wear life of traditional tool steels.
- 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.
- Precision Machining: CNC-machined barrel body with strict roundness, coaxiality, and straightness tolerance control. Quality inspected via CMM, ultrasonic testing, and surface finish measurement.

Precision Manufacturing 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. |

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).
