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
