Durable Twin Screw Extruder Screw Elements for Polymer Processing and Compounding Lines

The screw elements used in twin screw extruders are the essential components that define the efficiency, stability, and product quality of the entire extrusion process.
ZHITIAN screw elements are designed for continuous, high-load, and high-shear applications, ensuring excellent mixing and conveying performance while maintaining superior durability.

Each element is precision-machined using CNC equipment to achieve exact dimensional tolerance and perfect interlocking fit between segments. This precision guarantees stable torque transfer, optimized melt flow, and uniform material distribution.

ZHITIAN employs advanced materials such as 38CrMoAl nitrided steel, W6Mo5Cr4V2 high-speed tool steel, and PM-HIP grades (SAM26, SAM39, CPM10V, CPM9V). These materials deliver outstanding resistance against wear, corrosion, and high temperature — ensuring long-term reliability in polymer, masterbatch, and engineering plastics extrusion.

• Extended service life through advanced alloy materials
• High consistency between screw elements for precise assembly
• Reduced energy loss and smoother material flow
• Customizable design to fit any twin screw extruder model
