  • Mold design system and recording medium
    Patent number: 6546362
    Abstract: To quickly determine a parting line, a mold design system first obtains the orientations of faces constituting an article to be produced using a mold, and then classifies the faces according to their orientations. A boundary between faces that are classified into different sets is determined as a parting line. Thus, the parting line is automatically determined, permitting efficient mold design.
