The large free volume and high specific torque enable universal application of the ZE BluePower twin-screw extruders for compounding engineering plastics and even highly filled formulations. Thanks to the 1.65 OD/ID diameter ratio and the torque density of 16 Nm/cm³, these extruders are tailored for any customer-specific application – from the production of compounds, expanded sheets, biaxially oriented film and sheets up to the processing of recycled material.
Processing section of modular design for uncompromising flexibility
The large extruder variants with screw diameters of 98, 122, 142 and 166 mm still offer the typical screw and barrel modularity. A wide range of 4D and 6D barrel housings and various side feeders and degassing units are available for the extruder configuration. The exchangeable oval liners ensure efficient wear protection of the housings – a crucial benefit in wear-intensive compounding applications in particular.
Minor design modifications have been implemented by KraussMaffei to allow for the size of the new extruders. The housing elements are connected by means of screw unions instead of clamping flanges and the cartridge heaters are replaced by ceramic heaters.
