This combined with corporate research and development, has enabled Sai to offer barrel material, screw finishes and screw geometries for nearly every extrusion machine and plastics processing application. Screw designs within the Sai have evolved over several decades from simple single flight Geometries to sophisticated barriermixing designs. State-of-the-art advances in screw design have improved the melting and solids conveying capabilities of the single screw extruder, leading to higher productivity.
