  • Publication number: 20150231692
    Abstract: In a mold designing, a deformation amount of a casting from a solidification start time to a cooling end time may be obtained by deformation analysis software, and a deformation amount of a mold from a pouring time to the solidification start time may be obtained by deformation analysis software. When a cavity shape is designed based on the obtained deformation amounts of the mold and the casting, the precision of a near net shape may be further improved by reflecting the mold cavity shape at the solidification start time to the mold design, and a lack in dimension of a casting product after the casting process may be prevented.
