SK conveying elements provide approximately 15% higher free volume than standard conveying elements and are particularly suitable for low bulk density materials.
Best suited for:
Feeding zones
Side feeding
Low bulk density materials
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
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
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
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
