A molding device (1) includes a temperature control section (4) and a temperature control sequence determining section (3) that corrects a temperature control sequence for instructing the temperature control section (4) to operate, the temperature control sequence determining section (3) including predicting means (31) for predicting a temporal shift of a thermosetting material (H) and correcting means (32) for correcting a temperature control sequence on the basis of the temporal shift. This arrangement prevents thermal runaway during a process of molding a thermosetting material.
