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
Precision involute spline ensuring high torque transmission with accurate centering and load distribution.
Best suited for:
High torque extrusion
Engineering plastics
Masterbatch production
Triple flight elements provide strong distributive mixing with lower shear. They are commonly used in melt mixing sections where gentle material distribution is required.
Best suited for:
Melt distribution
Sensitive materials
Low-shear compounding
Simple keyed design for basic torque transmission in low-load extrusion systems.
Best suited for:
Low torque applications
Legacy extruders
PVC processing
Barrel with side feeding port for controlled addition of fillers, fibers or additives during processing.
Best suited for:
Fiber reinforcement
Filler addition
Multi-component compounding
Reverse kneading elements introduce backflow and pressure build-up, increasing residence time and enhancing mixing intensity.
Best suited for:
Before venting zones
Degassing preparation
High mixing demand sections
