Screw Barrel
Description
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 realized due to our patented barrier screw geometries Sai 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 feed screw and is responsible for the critical functions of feeding, solid conveying, melting, mixing and pumping.
Screw: Screw is made from material EN-41 B (MUSCO) Toughened, 3mm depth Bimetallic Coating on flite profile, Thread cutting, Grinding, Polishing and Gas Nitrating case depth 0.60mm hardness 68 HRC.
Barrel: Barrel is made from material EN-31 forged, toughened duly deep hole boring, Bimetallic Coating 3mm Radially & honing
