Innovative twin-screw extruders

For its twin-screw corotating extruders with a nominal diameter of 25 to 120 mm, COMAC, based in Cerro Maggiore (Milan), introduced the new configuration of plasticizing cylinders at PLAST 2012.
The main advantages in comparison to the traditional design are: the possibility to disassemble and reassemble the cylinder/bushing modules without tools, reducing need to handle heavy parts and speeding up maintenance; more accurate temperature regulation by means of probes placed very close to the inner surface in contact with the material being processed.
