1. A method for classifying temperature control branch of a molding tool according to an influence on a heat budget of a portion of the molding tool, the method comprising:
producing, by proceeding in production cycles, molded parts by using the portion of the molding tool, with introduction of heat into the molding tool, and/or cyclically activating a heating device, with introduction of heat into the molding tool,
conveying a temperature control medium through the temperature control branch of the molding tool to dissipate at least some of the introduced heat,
measuring a temporal branch temperature profile of the temperature control medium in the temperature control branch over several production cycles,
analyzing a curve behavior of the branch temperature profile and/or of a variable derived from the branch temperature profile over several production cycles, and
sorting the temperature control branch into one of at least two categories, according to greater and/or smaller influence on the heat budget of the portion of the molding tool, on the basis of the curve behavior.
