Twin-screw extrusion

Small quantities can be produced with a wide range of additives and fillers on five co-rotating, twin-screw extruders.

These extruders are equipped with modern online processing systems for process data as well as special screw geometries and feeding options, and can be used for a variety of processing tasks in consultation with our experts.
