Raw Material

The material for extrusion is usually supplied through vacuum conveying units either as single or as central feeding system.

The weighing of all components for the preparation of dry blend is subject to tight tolerances as the formulation of a batch is the essential factor for a consistent level of quality in regards to color fidelity, shape retention and surface quality of the extruded profile.

Mixing unit

The heating / cooling mixing combination retrieves contents of both weighing containers upon freely configurable mixing instructions. The compound is then heated in the heating mixer by friction heat and forwarded to the cooling mixer where it is cooled down to the required temperature. The mixture (dry blend) is then ready to be discharged to the post hopper.

Extruder with feeding unit

The feeder delivers the dry blend to the extruder hopper. When being moved towards the tool die through the extruder it is melted and condensed into a viscous mass by the screws.

Extrusion tooling

Under high pressure (up to approx. 400 bars) the dry blend is distributed and formed according to the required profile geometry in the extrusion die. To keep it dimensionally stable it is cooled down in the adjoining calibration.

Extrusion downstream

The extrusion downstream includes calibration table, puller, cutting unit and tip or sliding table. The calibration table supplies water and vacuum to cool and stabilize the profile. The puller provides a continuous feed of the profile strand towards the cutting unit, where the profile is cut to the required length and then stored.
