Lesun Screw, a global leader in twin-screw extruder parts, will present its high-performance parts at K 2025 in Düsseldorf, Germany (October 8-15, Booth 11H35-01). With a strong focus on precision engineering and material innovation, the company will demonstrate how its twin-screw extruder parts help customers enhance efficiency, reliability, and cost-effectiveness in extrusion production lines.
To meet the increasing demand for high-torque and long-life twin-screw extruder shafts, Lesun Screw has introduced advanced cold-forming technology, which elevates screw shaft manufacturing to a new level of precision and durability:
*Increased surface hardness and strength while maintaining core toughness
*Improved spline accuracy for optimal fit with screw elements, reducing vibration and wear
*Stable torque transmission supports high-speed and high-output twin screw extruder lines.
*Maximum load torque capacity of 18 Nm/cm² for extended service life
*Uniform stress distribution to enhance fatigue resistance
Lesun Screw will further demonstrate a range of high-performance extruder parts at K 2025: Special screw elements - Manufactured with high wear- and corrosion-resistant alloys, tailored for compounding and specialized processes
Screw barrels - High-durability designs engineered for longer service life and reduced maintenance requirements
Transforming Spare Parts into Performance Upgrades
By combining precision manufacturing with material innovation, Lesun Screw transforms standard twin-screw extruder parts into performance-enhancing solutions--helping customers reduce downtime, improve efficiency, and maximize extrusion performance.

Stretching elements, also called S-type elements, improve material exchange and distributive mixing in partially melted zones.
Best suited for:
Semi-plasticized material zones
Improved dispersion
Gentle mixing processes
Liquid Injection Barrel | Twin Screw Extruder Dosing Barrel
Single flight conveying elements provide higher conveying efficiency than standard double flight elements. Their wider flight design reduces leakage flow and increases pressure-building capability.
Best suited for:
Feeding sections
Extrusion zones
Applications requiring strong conveying force
Transition elements are designed to connect different screw element geometries while minimizing dead zones and material retention.
Best suited for:
Transition between single and double flight elements
Connection between SK and standard conveying elements
Geometry change zones within complex screw configurations
Forward kneading elements provide a balance between conveying and mixing, with adjustable shear depending on stagger angle and disc width.
Best suited for:
Plastication zones
General compounding
Controlled mixing processes
Six-sided geometry enabling uniform torque transfer and rapid screw element replacement.
Best suited for:
Powder coating
Frequent material changes
Fast screw configuration changes
