PROBLEM TO BE SOLVED: To highly accurately and stably control pressure in both a high pressure controlling process and a low pressure controlling process and to ensure high quality of molding. SOLUTION: In the low pressure controlling process, the pressure is controlled based on a result on detecting the pressure detected from the first load transducer 4 for detecting the low pressure placed between a driving mechanism part 2 side and a movable part 3 side and in the high pressure controlling process, the pressure is regulated in such a way that the pressure of at least a set pressure is not applied to the first load transducer by means of a regulating part 6 and the pressure is controlled based on a result on detecting the pressure detected from the second load transducer 5 for detecting the high pressure placed between a driving mechanism part 2 side and a movable part 3 side.
