Abstract
A method for the variothermal temperature control of an injection mould using a temperature control device, the method including at least the following steps: in a learning phase, determining a temperature control characteristic of the temperature-controllable system including at least the injection mould and the temperature control device, in order to obtain individual reference values for the system, with which the temperature control device can be controlled in order to obtain a nominal temperature profile; and in a production phase: temperature control of the injection mould with the reference values determined during the learning phase; determining deviations of an actual temperature profile of the injection mould in relation to the nominal temperature profile during the production cycle and calculating corrected reference values from these deviations; and carrying out a resulting production process using the corrected reference values.
