CO-ROTATIVE TWIN SCREW EXTRUDERS

we offer a wide range of extruders to satisfy all production targets, from laboratory test size to high volumes compounding.

All our extruders are characterized by:

Specific gear boxes for every production process; HT (high torque) and XT (extra torque) versions available.
Rectangular modular barrel in 4D length sectors ( available also in high volume version HV ); each single segment is built in "3 pieces" to enhance the following characteristics:
- Inner part in high wear resistance steel
- Thermoregulation devices contained in the external parts to obtain better thermostatting
- Faster and easier maintenance
Highly modular screws; different modules are available with several profiles, like kneaders and mixers, that can be assembled on screw splined shafts. Their carefully defined design avoids material stagnation, grants self-cleaning action and is specifically studied to obtain the best possible process results.
