1. An injection molding system configured of one or more computers each including a microprocessor and a storage device, the system comprising the steps of:
determining a manufacturing condition including a combination of a first mold and a first injection molding machine;
confirming presence or absence of a first track record in production, in which a combination of the first mold and the first injection molding machine is used, by searching a production-track-record storage unit; and
producing, in a case of the absence of the first track record in production, a corrected molding condition for injection molding by using the combination of the first injection molding machine and the first mold, based on first molding machine-specific information acquired in advance for the first injection molding machine, second molding machine-specific information acquired in advance for a second injection molding machine that is combined with the first mold and has a second track record in production, and the second track record in production acquired from the production-track-record storage unit,
wherein
the corrected molding conditions are produced such that the first injection molding machine and the second injection molding machine have the same part quality,
the step of producing the corrected molding condition corrects at least an amount of resin injected from the first injection molding machine to the first mold, and
the produced corrected molding condition is inputted to the first injection molding machine.
