Low-pressure production of cast article
Abstract:
Method for highly efficiently producing a cast article by a low-pressure casting process, wherein a molten metal is charged into a mold cavity of a gypsum mold. The cast metal immediately after its solidification is rectified into a final shape, in a state in which the solidified metal is either still integral with the gypsum mold or removed therefrom, requiring minimized time for rectification and cooling.
