Wear-Resistant Alloy Screw Elements for Coperion STS75 Granules Extruder

ADVS supplies premium wear-resistant alloy screw elements specifically designed for Coperion STS75 granules extruders. These elements are manufactured from advanced HIP alloy and Ni-based materials using CNC precision machining, with involute spline connections and polished surface treatment. They deliver outstanding durability and consistent compounding performance for granulation, sheet, and profile extrusion applications.

• HIP Alloy Technology — Hot Isostatic Pressing eliminates internal porosity, delivering fully dense material with maximum wear resistance
• Involute Spline Connection — precision-ground spline profile ensures secure, backlash-free mounting on STS75 screw shafts
• CNC Precision Machining — computer-controlled manufacturing guarantees exact element geometry for optimal conveying and mixing
• Polished Surface — mirror-smooth surface finish reduces polymer adhesion, improves self-cleaning, and extends cleaning intervals
• Multi-Material Processing — compatible with PE, ABS, PS, EVA, PET, PP, PBT, PA, and filled compounds
• ISO9001 Quality — comprehensive material certification and dimensional inspection reports provided
