Product Overview
Precision manufactured Single Screws for plastic extrusion, blown film plants, pipe plants, and injection molding machinery.
Our Single Screws are manufactured using specialized CNC whirling and thread milling machines. We use premium grade EN41B Musco alloy steel followed by advanced vertical gas nitriding to provide deep diffusion case hardness and maximum resistance against abrasive polymers.
Material Grades
EN41B (38CrMoAlA), SACM 645, H13, D2
Hardness Rating
950 - 1050 HV (65 - 70 HRC), Nitriding Depth: 0.5 - 0.8 mm
Key Technical Advantages
- Optimized L/D ratios (18:1 to 36:1) for homogenous plasticizing
- High torque capacity with low shear stress
- Mirror-polished flight channels for residue-free color transitions
- Straightness tolerance within 0.02 mm per meter
