  • DIRECTIONAL SOLIDIFICATION CASTING ASSEMBLY AND METHOD
    Publication number: 20230264255
    Abstract: A directional solidification casting method includes fluidly coupling a feed line conduit with a source of molten metal and with a directional solidification mold at a gating. The mold has an interior chamber with a shape of an object to be cast using directional solidification in a growth direction. The feed line conduit is fluidly coupled with the gating in a downward direction oriented at an angle that is closer to the growth direction of the mold than to another direction that is perpendicular to the growth direction of the mold. The method also includes positioning a downstream portion of the feed line conduit below the gating, directing the molten metal into the mold via the feed line conduit, and casting the object in the mold using directional solidification.

  • Directional solidification casting assembly and method
    Patent number: 11590563
    Abstract: A directional solidification casting assembly includes a directional solidification mold having an interior chamber with a shape of an object to be cast using directional solidification of molten metal in a growth direction of the mold and a feed line conduit. The conduit is fluidly coupled with a container source of the molten metal and is coupled with the mold at a gating. The feed line conduit conveys the molten metal into the mold through the gating for directional solidification of the object to be cast in the mold. At least a downstream portion of the feed line conduit that is between the intermediate location of the feed line conduit and the second open end of the feed line conduit is located below the gating along the growth direction of the mold.
