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:

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
