The Sai single screw extruder is a product of heavy research & development. This confirms the dominance of Sai in extrusion field.

The GearBox is designed for transmitting the high torques & for coping up with the maximum thrust load. It has space-saving construction. High efficiency is achieved with helical gears of high quality forged steel, hardened & ground.

The Thrust housing is designed for bearing the maximum force and not allowing the thrust pressure to damage the reduction gears as Sai provides high-quality Thrust Roller Bearing. The screw is combined with a special grooved barrel having a properly equilibrated geometry. The melting process is determined by the barrier zone. The separation between the solid and liquid phase is achieved, maintaining the solid bed up to the complete melting. The role of the metering zone is to homogenize the molten material and give high output without pulsation.

The space-saving Mobile Extruders usually operators in conjunction with the fixed horizontal extruder. Thus in combination provides extra flexibility to insulate automotive wires, optical fibre buffering, etc. and also employed as an auxiliary extruder for skin insulation, striping & coloring.
