Sai offers standard application finished screws through flight tipping as well as fully encapsulated screws. 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 barrier/mixing 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. The most significant advances in melting are being realised due to our patented barrier screw geometriesSai can supply almost any size of extrusion screw for almost any application, and also offer a comprehensive rebuilding service too.

Just remember the most important element in any extrusion system is the fe
