In the realm of extrusion technology, the SK screw element stands out as a pivotal component, particularly in the blanking and side feeding sections of the process. Renowned for its ability to augment storage capacity and alleviate pressure within these segments, the SK screw element plays a crucial role in optimizing extrusion operations.
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
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
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
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
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
SME elements introduce shallow reverse grooves on conveying flights, generating controlled melt backflow and improving distributive mixing.
Best suited for:
Melt stage mixing
General distributive mixing
Applications requiring good self-cleaning
