ZHITIAN provides OEM replacement and custom screw elements engineered for seamless compatibility with leading twin screw extruder brands such as Coperion, Leistritz, Berstorff, Theysohn, JSW, Toshiba, and USEON.
Each element is designed with precision machining and advanced metallurgy to ensure identical geometry, tight tolerances, and stable performance equivalent to or exceeding the original manufacturer’s standards.
Our screw elements are manufactured to achieve optimal mixing, conveying, and shearing efficiency across a wide range of applications — from plastic compounding and masterbatch production to chemical and food extrusion.
We provide various types of elements, including:
Conveying elements
Kneading blocks
Mixing elements
Reverse elements
Special flow-modifying geometries
Each design supports smooth material flow, uniform dispersion, and enhanced process stability.
To meet diverse application needs, ZHITIAN offers multiple material options ensuring high wear and corrosion resistance:
| Material Type | Typical Grade | Application |
|---|---|---|
| Tool Steel | W6Mo5Cr4V2 | Standard wear-resistant use |
| Nitrided Steel | 38CrMoAlA | Corrosion and oxidation protection |
| PM-HIP Alloy | SAM26 / SAM39 / CPM10V | High wear & corrosion environments |
| Stainless Steel | 316L | Food & chemical extrusion |
| Tungsten Carbide Coating | WC / Ni-based Alloy | Extreme abrasion and high-load conditions |
These materials undergo CNC precision machining, heat treatment, and surface hardening, ensuring durability and consistency across long production runs.
ZHITIAN provides 3D scanning and CAD reverse engineering to replicate OEM elements accurately. Even if no technical drawing is available, our engineers can restore complete design data from worn or sample parts, ensuring:
Exact geometry reproduction
Full material matching or performance upgrade
Fast lead time for international customers
This service supports users of discontinued or legacy extruder models, allowing continuous operation without interruption.
Full compatibility with global extruder brands
Custom design for specific compounding processes
Superior wear & corrosion resistance materials
ISO9001-certified quality control
Global export experience across Europe, America, and Southeast Asia
Q1: Can you manufacture screw elements without original drawings?
A1: Yes. We can reverse-engineer using 3D scanning and sample measurement, ensuring precise geometry replication.
Q2: How long is the production lead time?
A2: Typically 2–4 weeks depending on material and quantity.
Q3: Which brands do your OEM elements fit?
A3: Coperion, Leistritz, Berstorff, JSW, Theysohn, Toshiba, and many more.
Q4: Do you provide material certificates and inspection reports?
A4: Yes, full QC documentation is included with every order.
