Do you operate large-scale petrochemical or chemical extrusion lines? We manufacture high-performance ZSK250 Screw Segments (OD 247.9 mm) to keep your high-tonnage production lines running smoothly.
Large-diameter twin screw extruders operate under immense torque and extreme throughput demands. Therefore, we use premium wear-resistant and corrosion-resistant alloy steels for all ZSK250 components. Furthermore, our advanced CNC machinery guarantees precise outer diameter tolerances and tight inter-meshing clearances.
We supply conveying elements, kneading blocks, and specialized mixing segments for ZSK250 machines. As a result, our high-precision parts extend component service life and lower overall operating costs.
Engineered for Heavy Petrochemical Processing:
We design these OD 247.9 mm screw segments specifically for high-capacity chemical compounding. Consequently, they handle continuous high-torque extrusion without structural fatigue.
Superior Wear and Corrosion Resistance:
We offer high-grade nitriding steels, bimetallic alloys, and powder metallurgy materials. Therefore, our parts withstand aggressive chemical additives and highly abrasive polymers.
Precision CNC Thread Grinding:
We machine every element to exact dimensional tolerances. Thus, you achieve efficient self-wiping action, consistent melt quality, and higher throughput every hour.
100% Direct Fit Guarantee:
We manufacture all components strictly according to ZSK250 technical standards. Because of this, your maintenance team can replace worn parts quickly during scheduled overhauls.

Our heavy-duty OD 247.9 mm ZSK250 screw segments excel across demanding polymer and chemical processing operations:
Polyolefin Resin Production: Post-reactor pelletizing and compounding for Polypropylene (PP) and Polyethylene (PE/HDPE/LLDPE).
Engineering Plastics Compounding: High-capacity processing of Polyamide (PA), Polycarbonate (PC), PET, and PBT with glass fiber or mineral fillers.
Masterbatch & Additive Manufacturing: Production of high-density color masterbatches, flame retardant batches, and filler concentrates.
Chemical Reaction & Devolatilization: Continuous reactive extrusion, monomer stripping, and solvent removal in chemical plants.
Rubber & Elastomer Processing: Mixing, homogenization, and pelletization of synthetic rubbers (EPDM, SBR) and thermoplastic elastomers (TPE/TPR).
Large-Scale Polymer Recycling: High-throughput filtration and reprocessing of post-industrial and post-consumer plastic waste.
A: Yes, absolutely. We manufacture all ZSK250 components strictly to standard OEM dimensions and tolerances. Furthermore, we test every piece on precision coordinate measuring machines (CMM) before delivery. Consequently, our parts fit your machine perfectly without modifications.
A: Your choice depends on your chemical formulation. For standard polyolefin processing, we recommend 38CrMoAlA or 41CrAlMo7 nitrided steel. However, if your process involves corrosive chemical additives or high fiber content, we recommend HIP powder metallurgy alloys. As a result, you maximize wear resistance and avoid costly unexpected shutdowns.
A: Yes, we can. Our engineering team operates state-of-the-art CNC thread grinding centers. Therefore, we easily produce custom mixing profiles, special kneading blocks, or modified conveying elements. Simply email us your 2D/3D CAD drawings for a fast evaluation.
