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.
