Extruders

MWB Design Pty Ltd ‘SL’ series range of extruders are designed and built in Australia. Low centre line heights making them ideal for small to medium blown film applications or custom mounting for co- extrusion applications.

  • Screw diameters from 25mm up to 65mm with L/D ratios from 20/1 to 30/1

  • *Outputs from 4.5kg/hr to 115 kg/hr

  • *Based on LDPE/LLDPE 2.5 MFI with barrier screw. 24/1 LD ratio

Standard equipment level includes:

MECHANICAL

  • Heavy duty “low noise” integral thrust gearbox with minimum mechanical service factor equal to 1.8. Thrust bearings SKF 29..... E series.

  • Screw: metering/mixing/barrier depending on polymer to be processed. Nitrided or hardfaced.

  • Barrel with integral feed and cooling jacket. Nitrided or bimetallic. 7500 psi rupture plug fitted.
