1. Specification of the SJSZ 80/156 Extruder



Performance features:

• Screw: Big output & L/D ratio. Two stage unique design effects, with low temperature plastication concept.

• Barrel: barrel is made of special steel alloy, and is equipped with aluminum thermal foil with air cooling system.

• Gearbox: gears are made of steel alloy with heat treatment and are finished with surface precision grinding. By using oil injection cooling system, it reduces noise when operating under high RPM and enhances the life span of gears.

• Motor: AC motor, selected famous brand products. Controlled by ABB/DELTA  Inverter.

• Control system: Adopt selected high quality and famous brand products from Europe, and Japan manufactures. Machine works more stable and longer working-period.
