ABSTRACT:
Heat-up characteristics are obtained individually for a plurality of heat zones of an injection molding machine. A heat-up time is obtained from the heat-up characteristic of each heat zone and the difference between a preset temperature and an actual temperature. A heat zone that requires the longest heat-up time is specified. Heat-up of each heat zone is controlled in accordance with the longest heat-up time.
