Abstract: An injection molding condition generation system improves the quality of injection molding. The injection molding condition generation system acquires a material property value of a resin material and an injection molding condition using the first resin material based on a target value of a quality parameter related to a quality of a molded article, the first material property value, and a predetermined relational expression. The predetermined relational expression indicates a relation among the material property value of the resin material, a plurality of injection molding conditions input to an injection molding machine, and a quality parameter related to the quality of the molded article molded by the injection molding machine based on the material property value and the injection molding conditions, and is generated based on data accumulated in the memory in association with the material property value of the resin material, the injection molding conditions, and the quality parameter.
