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.

High-Performance ZT Series Alloy Materials

Zhitian's proprietary ZT Series high-performance alloys include:

ZT610 Nickel-Copper Alloy
ZT615 Nickel-Chromium Alloy
ZT625 Nickel-Based Tungsten Carbide
ZT715 Nickel-Tungsten/Nickel-Based Tungsten Carbide
ZT725 Nickel-Based Tungsten Carbide
ZT735 Nickel-Based Tungsten Carbide
ZT818 Cobalt-Based Tungsten Carbide

Manufactured using advanced technologies including hot-press sintering, laser cladding, and cold isostatic pressing.

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.

Typical Applications

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).
