Le varie tipologie di estrusori bivite co-rotanti variano per velocità e densità di coppia, hanno diametri viti compresi tra i 18 ed i 175 mm e vengono forniti con configurazioni ottimizzate, sfruttando a pieno il principio di modularità che fa da base alla loro progettazione.

I cilindri a spezzoni componibili possono essere forniti con termostatazione ad acqua o ad aria, in acciaio da nitrurazione o con bussole estraibili resistenti all’usura e in rapporti L/D specifici.

High performance

In order to target production increases and energy savings, these new models of co-rotating extruders combine the advantage of a higher free screw volume with the advantages of higher specific torque, in an energy-efficient design.
The powerful machines can handle an extensive array of compounds and applications, and produce extrusion to the highest quality standards.

Performance

  • Highly flexible modular system
  • Energy saving, low specific-energy consumption
  • High intake capacity of feed screws
  • Fast recipe or colour change due to self-wiping geometry
  • High plasticisation capacity
  • Calibrated control of melt temperature
  • High homogenising/distributive mixing capacity
  • High dispersive mixing capacity
  • Fine-tuning of residence time-shear/elongation stresses parameters balance
  • High venting efficiency due to the large surfaces and to the system’s modularity
