  • Publication number: 20090218067
    Abstract: The inventive casting method consists in extruding a melt from a metal reservoir into the cavity of a shaped investment mold at a temperature above liquidus and a pressure enabling a maximum splash-free liquid metal flow and increasable along with the melt crystallization to a pressure sufficient for further filling the mold in proportion to the amount of cast shrinkage. The inventive device for carrying out said method comprises a metal reservoir arranged as a removable insert lined from the inside and provided with an annular flange, and a container which comprises the shaped investment mold and a hollow neck provided with a removable thimble. The flange is mounted in such a way that its inner diameter matches with the outer diameter of the thimble, wherein the inner diameter of the flange is smaller than the inner diameter of the insert.
