A method for operating an extruder that has a screw, including the steps: (a) detection of a formulation identifier which is associated with material to be extruded and which encodes at least one operating variable, from which an ideal screw rotational frequency of the screw, which is to be set for the extrusion process, can be determined, (b) time-dependent detection of a throughput parameter, from which a throughput of the extruder can be deduced, (c) detection of a non-conformance point in time, at which the material can no longer be produced with a predefined quality, owing to excessive wear of the extruder, and (d) calculation of a limit throughput parameter from the throughput parameter, linking of the limit throughput parameter to the formulation identifier, and storing of the limit throughput parameter. 11014.
