Abstract: A method for managing a casting process based on measured properties of molding sand is provided so that casting defects or energy used can be reduced by changing the molding conditions for the mold to be produced or changing the steps after molding. The method for managing a casting process based on the properties of the molding sand includes a step (1) of measuring the properties of the molding sand just before the molding sand is supplied to a molding machine (40) and a step (2) of determining if the measured properties of the molding sand comply with predetermined properties so as to then switch between a step of molding a mold when the measured properties do comply with the predetermined properties and a step of molding a mold when the measured properties do not comply with the predetermined properties.
