PROBLEM TO BE SOLVED: To prevent the generation of a sink when manufacturing a thick-walled molded product, and to improve manufacturing efficiency. SOLUTION: In the molding apparatus 190 facing an injection device 150 of an injection molding apparatus 130, operation for performing respective processes of the application of secondary pressure and solidification by moving one mold 140a after the injection process of a molten resin is completed to a second retraction position 200b being the other position in the injection molding apparatus 130, and operation for moving the other mold 140b in which the secondary pressurizing and solidification process are completed to the molding position 190, and performing an injection process of the molten resin to the mold 140b from which a molded product (auxiliary mirror 110) is discharged by opening the mold 140b are alternately performed.
