Custom Twin Screw Extruder Screw Elements with Wear and Corrosion Resistant Alloys

Product Overview – Twin Screw Extruder Screw Elements

ZHITIAN’s Twin Screw Extruder Screw Elements are precision-engineered components designed to deliver efficient material conveying, mixing, and kneading in co-rotating twin screw extruders.
Every element is CNC-machined to micrometer-level tolerances, ensuring smooth engagement and consistent torque transfer during high-speed operation.
These components are ideal for compounders requiring long service life and accurate process control across a wide range of polymer and chemical applications.

Material Selection for Twin Screw Extruder Screw Elements

ZHITIAN offers a comprehensive portfolio of wear-resistant and corrosion-resistant materials for screw element manufacturing:

• 38CrMoAla (Nitrided Steel) – Cost-effective option for general plastic compounding.
