Abstract
A method for controlling temperature rise in divided heating zones of a barrel of a molding machine includes: setting tentative target temperatures for the respective heating zones; simultaneously raising temperatures in the heating zones to the set tentative target temperatures; when temperatures in the heating zones reach the respective tentative target temperatures, selecting a master zone from the heating zones, and selecting, as a slave zone, a heating zone which is other than the master zone among the heating zones; and after temperatures in the heating zones reach the respective tentative temperatures, raising the temperatures in the master zone and the slave zone to respective final target temperatures according to an attainment degree of temperature rise in the master zone.
