Lesun Screw manufactures high-precision screw elements, shafts, and barrel components compatible with a wide range of global twin-screw extruder brands. From high-torque compounding systems to specialized engineering plastics extrusion lines, our components are designed to ensure reliable interchangeability, stable processing performance, and extended service life.
With years of experience supporting OEM replacement projects worldwide, we understand that true compatibility is more than matching dimensions. It requires deep knowledge of spline structures, process behavior, material wear characteristics, and torque transmission requirements across different extrusion platforms.
Whether you are replacing worn components, optimizing an existing screw configuration, or sourcing spare parts for discontinued machine models, Lesun Screw provides engineering-focused solutions built for real production environments.
Lesun Screw supports a broad range of globally recognized twin-screw extruder systems used in engineering plastics compounding, masterbatch production, recycling, food processing, bioplastics, and specialty applications.
Our compatible solutions cover leading machine platforms including:

Each compatible component is manufactured according to precise dimensional verification and application-specific performance requirements, helping customers maintain stable production while reducing replacement lead times and operating costs.
At Lesun Screw, OEM compatibility is not treated as simple duplication. Every compatible component is developed through detailed engineering analysis and manufacturing control to ensure reliable integration into existing extrusion systems.
Our engineering process includes:
Existing components can be analyzed through advanced dimensional inspection, spline profile measurement, centerline verification, and modular geometry reconstruction. This enables accurate reproduction of critical structural features required for stable assembly and operation.
Different extrusion applications demand different wear solutions. Depending on the processing conditions, Lesun Screw provides compatible components manufactured from tool steels, PM materials, HIP alloys, and customized heat-treatment systems to ensure long-term wear resistance and operational stability.
A screw element that merely "fits" is not enough. Feeding efficiency, melting behavior, mixing characteristics, pressure stability, and torque transmission must all remain consistent after replacement. Our manufacturing approach focuses on preserving actual process performance under real production conditions.
Strict machining tolerances and quality inspection procedures ensure that compatible components integrate smoothly with existing OEM systems while maintaining assembly precision and operational reliability.
Lesun Screw supplies a complete range of compatible twin-screw extruder spare parts for various OEM platforms.
Including conveying elements, kneading blocks, mixing elements, toothed components, and customized geometry designs for different compounding processes. Available in multiple wear-resistant material grades for demanding applications such as glass fiber reinforced plastics, mineral-filled compounds, and recycling materials.

Our engineering team understands that different materials create different wear mechanisms, torque loads, and process requirements. This allows us to recommend compatible solutions optimized not only for the machine platform, but also for the actual production application.
Many extrusion manufacturers and compounders are seeking alternatives to standard OEM spare parts due to long lead times, limited customization flexibility, and increasing replacement costs.
Lesun Screw provides a practical and engineering-driven alternative by offering:
Faster production and delivery cycles
Flexible customization support
Application-oriented wear solutions
Stable dimensional interchangeability
Competitive replacement costs
Technical support for configuration optimization
Support for legacy and discontinued machine models
For many customers, compatible spare parts are not simply a purchasing decision — they are part of maintaining production continuity and improving long-term operating efficiency.
A successful replacement component must do more than install correctly. It must maintain stable extrusion behavior under real operating conditions.
Lesun Screw focuses on delivering compatible solutions that support:
Stable feeding performance
Consistent melting efficiency
Reliable mixing behavior
Smooth torque transmission
Reduced abnormal wear
Long-term operational stability
This engineering-focused approach helps customers reduce downtime risks while maintaining consistent product quality across demanding production environments.
