Abstract
The invention relates to a method for adjusting an extrusion die in an extruder by recording at least one master flow curve () in a first extruder to which the extrusion die is optimized, in which curve the volume flow is entered over the pressure, which master flow curve () is obtained in a measuring channel () which branches off in the extruder, the extrusion die or in any interposed adapter part from the flow channel (), and the repeated recording of flow curves () in the same or similar measuring channels () as in the first extruder after the assembly of the extrusion tool in the extruder to be checked and adjusted, and the purposeful change of process parameters for such a time until the flow curves () correspond to the master flow curves () within predetermined tolerance ranges.
