Primary feeding barrel introducing raw materials into the extruder under controlled fill and stable conveying conditions.
Best suited for:
Main material feeding
Pellet and powder input
Stable process start
ZME elements combine reverse conveying structure with forward teeth, creating intensive cutting and recombination of melt flow.
Best suited for:
High mixing intensity applications
Difficult-to-disperse materials
High-performance compounding
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
Simple keyed design for basic torque transmission in low-load extrusion systems.
Best suited for:
Low torque applications
Legacy extruders
PVC processing
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
