description The invention relates to a method for operating an extrusion system (10) with the automatically executed steps (a) time-dependent detecting of at least two operating parameters (P), which are selected from the following list: (i) a screw revolution parameter (U), from which are able to be determined the number of revolutions which a conveying screw (26) of an extruder (12) of the extrusion system (10) has carried out since a predetermined time, and/or (ii) a torque characteristic, which describes the torque (M) which is applied to the conveying screw (26), and/or (iii) an operating pressure in a cylinder of the extruder (12) and/or (iv) an abrasion parameter (C), which describes an abrasivity of material processed in the extruder (12), (b) from the operating parameters (P) computation of a wear parameter (V), in particular of a service time (TW), which encodes a wear state of at least one component of the extruder (12), and (c) emitting of a servicing notification, which encodes the wear parameter.
