An injection moulding machine having a machine controller and a control unit, capable of starting up the injection moulding machine from a switched-off mode or a standby mode into a production operation for producing injection-moulded parts and to shut down back into a switched-off or standby mode. Start-up and shutdown of the injection moulding machine are each divided into a number of phases, and a sequence of specific machine movement commands and/or specific machine mode change commands is pre-programmed for each phase of start-up and for each phase of shutdown. One or more control elements are provided on the control unit which, when actuated, activate a pre-programmed sequence so that a phase of start-up or shutdown can be started, the functions of start-up or shutdown of the injection moulding machine associated with the machine movement command and/or the machine mode change command of this sequence then being triggered.
