The invention provides an injection molding system. Types of molded articles carried by a carrier are identified and the molded articles are sorted based on image-related information for the molded articles molded based on set operating conditions for injection molding machines and molded article images acquired by an image acquisition unit. It is thus possible to narrow down candidate images in processing in a molded article identification unit, thereby making it possible to construct an injection molding system that has excellent production efficiency with a reduced load on processing in the molded article identification unit.
