Performance of an injection molding machine is improved. The injection molding machine includes: a central controller centrally controlling an injection molding operation; a first injection apparatus performing an injecting operation of material, based on a first injection start signal output from the central controller; a second injection apparatus performing an injecting operation of material, based on a second injection start signal output from the central controller; and a mold clamping apparatus performing a mold clamping apparatus. The injection molding machine is configured to adjust a time difference between a first injection start timing of the material injected from the first injection apparatus and a second injection start timing of the material injected from the second injection apparatus.
