An object is to provide a molding method and a molding machine which can reduce load acting on a drive section for mold clamping, as well as a molded product produced by the molding method or the molding machine. The method includes the steps (the molding machine includes means) for charging a molding material into a cavity a plurality of times; performing mold clamping each time the molding material is charged; and retreating, at a predetermined timing, a base plate by a predetermined mold thickness adjustment amount so as to adjust the origin position of a toggle mechanism. In this case, a molding material is charged into the cavity a plurality of times; mold clamping is performed each time the molding material is charged; and at a predetermined timing, the base plate is retreated by a predetermined mold thickness adjustment amount whereby the origin position of the toggle mechanism is adjusted. Since the compressing force increases, the load acting on a drive section for mold clamping can be reduced.
