Why our Extrusion Line stands out

Our twin-screw and co-extruders, downstream modules, and the C6 control platform are globally proven and tailored to your requirements. Energy-efficient drives and optimized screw designs provide a wide processing window, even for highly filled or heavily pigmented compounds. Parallel twin screws (32 L/D) ensure high throughput up to 800 kg/h* with consistent quality, while conical twin screws handle flexible profiles. Co-extruders can be easily integrated, and the ppC multitouch HMI supports energy monitoring, recipe management, and ERP/MES connectivity for semi- or fully autonomous operation.
