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
CKE elements combine conveying and mixing functions, providing gentle material exchange with low shear and reduced energy consumption.
Best suited for:
Heat-sensitive materials
Low-shear compounding processes
Applications requiring stable conveying with mild mixing
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
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
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
TME elements use intermeshing toothed discs to split and recombine melt flow, achieving efficient distributive mixing without conveying.
Best suited for:
Melt mixing zones
Fiber-reinforced materials
High homogeneity requirements
