Co-rotating Extruders
A complete range of co-rotating extruders at max speed & torque from 18 to 175 mm, all already manufactured and in operations to our customers.
Extruders are design according to the specific process and optimized to fully exploit the engineered modularity. high-performance barrels constructed of nitride steel can be supplied in different L/D ratios with air or water cooling system options, and equipped with optional wear-resistant liners.
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
