-
Broad Size Coverage (Φ15.6 – Φ430mm):
We produce special screw elements from small laboratory scale up to massive commercial extrusion lines. Consequently, we meet all your facility needs under one roof.
-
Superior Mixing and Dispersion:
Our ZSE50 kneading blocks provide optimal dispersion and distribution of additives. Therefore, you achieve consistent plasticization and homogeneous melt quality.
-
High Wear and Corrosion Resistance:
We select premium nitriding steels, tool steels, and bimetallic alloys. Thus, our components withstand harsh abrasive fillers and aggressive chemical additives.
-
100% Direct Fit Guarantee:
We machine all parts strictly to standard factory tolerances. Because of this, your maintenance team can replace worn elements quickly without modifications.

Our precision ZSE50 special screw segments and kneading blocks excel across demanding compounding tasks:
-
Engineering Plastics Compounding: Homogenizing PA, PBT, PC, PET, and ABS reinforced with glass fibers or mineral fillers.
-
Masterbatch & Additive Production: Distributing high-density pigments, flame retardants, and processing aids uniformly.
-
Reactive Extrusion & Devolatilization: Providing precise shear for continuous chemical reactions and monomer removal.
-
Thermoplastic Elastomers (TPE/TPU/TPR): Mixing sensitive elastomers smoothly without thermal degradation.
-
Recycled Plastics Repelletizing: Handling post-industrial and post-consumer plastic scrap while maintaining steady pressure.
A: Yes, absolutely. We manufacture all ZSE50 components strictly according to standard dimensions and tolerances. Furthermore, we inspect every element on precision measuring machinery before delivery. Consequently, our parts fit your machine seamlessly without extra machining.
A: Your choice depends on your processing goal. Use standard conveying elements for material transport and pressure building. However, use special kneading blocks when you need intensive melting, pigment dispersion, or high shear mixing.
A: We keep standard raw steel profiles in stock continuously. Therefore, we usually ship standard replacement elements within 7 to 10 working days. However, large-diameter parts or specialized bimetallic alloys may require 15 to 20 days.
Don't let worn kneading blocks ruin your melt quality or reduce your output.
We offer factory-direct pricing, precision CNC manufacturing, and fast worldwide delivery for ZSE twin screw components.
