Precision Replacement Screw Elements Designed for Compatibility
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.
Optimized Design for Twin Screw Extruder Performance
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.
Available Materials for Different Processing Demands
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.
