1. A method for quality control and/or tracking of an injection molding part produced in a production cycle with at least one processing machine of the plastics-processing industry, and upstream and/or downstream production devices or stations, which include reservoirs or hoppers for a material; granulate dryers; material distributors; conveying devices; metering devices; temperature control units; flow controllers; and at least one of robots, camera systems or measuring devices for quality control, which are interconnected via a network, the method comprising:
assigning to each individual injection molding part or a specific number of injection molding parts a quality contribution consisting of a plurality of quality contributions from a start of granulate conveying to a finished injection molding part,
wherein each of the devices or stations in the production cycle generates a respective one of the plurality of quality contributions, which includes at least one of a device contribution or a material contribution, extends the respective one of the plurality of quality contributions by quality contributions of upstream devices or stations, and forwards the respective quality contribution to a downstream device or station.
