In the field of nylon modification processing, has your twin-screw extruder ever faced issues of uneven mixing, quality fluctuations, or capacity bottlenecks? Many users may not yet realize that the solutions to these challenges often lie within the core components of the equipment.
As a leader deeply engaged in the core technology of twin-screw extrusion, Nanjing Lesun Screw Co., Ltd. understands that the quality of core components is the lifeline for stable and efficient modification processing!

A Tool for Upgraded Mixing Effects
Nylon modification demands extremely high standards for dispersive and distributive mixing. The special specification screw elements developed by Lesun Screw can achieve gentler and more uniform mixing compared to conventional shearing elements, significantly reducing molecular chain degradation caused by excessive shearing. This enhances the mechanical properties and consistency of the appearance of nylon-modified materials.
Precision Equals Quality
The machining accuracy, surface roughness, and batch consistency of screw elements, barrels, and shafts directly determine the stability of melt conveying, the uniformity of residence time distribution, and the quality of the final product. Differences as small as a millimeter can affect the key performance indicators of nylon-modified materials. Lesun guarantees the high quality of each batch of nylon materials with precision manufacturing on a military level.

High Torque, Greater Future
Nylon modification is developing toward higher filling, stronger alloys, and higher efficiency. Lesun understands the significance of high-torque twin-screw extruders for nylon processing—stronger conveying capacity, higher output limits, and better energy efficiency are the cornerstones of meeting future challenges. All of this relies on the extraordinary mechanical strength and reliability of core components.
Facing the future, Lesun is making a bold move! The cold rolling shaft machining technology, which Lesun invested over 20 million, will be mass-produced in 2025! This breakthrough in core technology, synchronized with world-class levels, will completely solve the stability and reliability problems of ultra-high torque models with torque coefficients above 13. The cold rolling process endows the shaft with unparalleled surface hardness, fatigue strength, and dimensional stability, providing rock-solid support for the demanding processing of high-end nylon modifications (such as high-temperature nylon, long-chain nylon, high glass fiber reinforced nylon), helping customers reach new heights in material performance and production efficiency.
