Lesun Screw: The Reliable Partner Supporting Quality and Efficiency in Nylon Modification
Lesun Screw: High-Performance Screw Elements and OEM Components for Twin-Screw Extruders
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
Double flight conveying elements are the most widely used design in twin screw compounding. They provide the best balance between free volume and torque transmission.
Best suited for:
Feeding sections
Venting zones
Pressure control sections
Cold-Forming high-torque shaft with improved strength and fatigue resistance for demanding extrusion conditions.
Best suited for:
High torque extrusion systems
High filler compounding
Continuous high-load production
Robust rectangular spline design providing stable torque transmission with moderate load capacity.
Best suited for:
Medium torque systems
Chemical processing
Replacement applications
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
Neutral kneading elements provide strong mixing with minimal conveying effect, ensuring stable residence time and high mixing efficiency.
Best suited for:
High mixing zones
Sensitive formulations
Residence time control
