Abstract: A cast product management system includes: an acquisition unit configured to acquire, from an input terminal, information on a defect of an inspected cast product; a database configured to the information on the defect acquired by the acquisition unit and information on a period when the cast product is manufactured in association with each other; and an output unit configured to output a time-series transition of the information on the defect with reference to the database.

Abstract: Provided is a technique that allows an operator or the like to easily perceive a tendency of defects which are present in molds or patterns. A display device displays a result of inspection of a plurality of molds or a plurality of patterns which are inspection target objects. The display device classifies the inspection target objects into a plurality of groups, generates, for each of the plurality of groups, a heat map image from a result of defect inspection of one or more of inspection target objects which are classified into the each of the plurality of groups, the heat map image representing a spatial distribution of defect occurrence frequencies; and causes a display to display one or more of the heat map images generated, the one or more heat map images corresponding to one or more groups specified by a user from among the plurality of groups.

Abstract: A mold molding apparatus can successively mold casting molds having the necessary casting mold strength, and a method for controlling the mold molding apparatus. A molding sensor measures a pressure of molding sand exerted on a surface of one or both of a pattern plate and a squeeze foot, or on a surface of one or both of a pattern plate and a squeeze board; and a control device that controls operation of the mold molding apparatus based on outputs from the molding sensors.

Abstract: Providing a method for reducing occurrences of a mold shift of a cope and a drag that have been molded by a flaskless molding machine and have been assembled by estimating a cause of a mold shift based on measurements and by taking appropriate measures, and a flaskless molding line that uses the method. The method for reducing occurrences of a mold shift of a cope and a drag (1, 2) that have been molded by a flaskless molding machine (200) and have been assembled comprises a step of measuring specific data at positions where a mold shift may occur during a process for manufacturing or taking out the cope and the drag, and a step of determining if the obtained specific data are within an allowable range.

Abstract: [Problem] To provide a marking method and a marking device for a casting that are, even when foreign matter is adhered to a casting to be marked, capable of making an effective and appropriate mark on the casting.
[Solution] Detect foreign matter on an outer surface of a casting 100, set marking locations 118, 120-1, 120-2, and make a mark on the marking locations 118, 120-1, 120-2.
