The SAI Engineering Company single screw extruder is a product of 10 years of research & development. This confirms the dominance of SEC in extrusion field. The Gear Box 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 SEC provides high quality Thrust Roller Bearing.
- Screw & Barrel are the most important elements of an Extruder.
- The Barrel is made of special alloy steel, nitrided and honed designed for bearing the pressure of maximum 1000 Bar. A spiral grooved barrel allows forced feeding, this increases output and guarantees remarkable stability and linearity over the entire speed range.
- The screw is made of special alloy steel, nitrided, polished, and bored throughout for oil heating cooling with thermo regulation system. The screw is combined with a special grooved barrel having a properly equilibrated geometry.
- The melting process is determined by the barrier zone. Separation between the solid and liquid phase is achieved, maintaining the solid bed up to the complete melting.
- The role of metering zone is to homogenize the molten material and give high output without pulsation.
- Extruder control is through a Modular Automation System which is assembled in line with customer requirement & optimize the extruder as single unit and as a part of complete line.
