PROBLEM TO BE SOLVED: To improve the reproducibility of the temperature of a material to be molded and to shorten the time necessary for the temperature of the material to be formed to attain a target temperature. SOLUTION: This glass form machine has a first core, a second core, a drum mold, a heating device which heats the first core and the second core, a pressurizing device which applies pressurizing force on the second core, a first temperature detector which detects the temperature of the drum mold, a second temperature detector detects the temperature of at least one of the first and second cores and a controller 70 which controls the temperature of the blow mold in a first stage and controls the temperature of the cores in a second stage. An electric power command value W3 diminishes with a start of the first stage and, therefore, the temperature of the blow mold may be prevented from rising extremely higher than the temperature of the cores at the point of the time the temperature of the cores attains the second target temperature.
