Abrégé

A counter-gravity casting method and apparatus in which the mold is held stationary and the crucible is moved generally laterally from a melt chamber to a fill chamber positioned below the mold with respect to gravity. A casting chamber is located generally above the fill chamber with respect to gravity. The method and apparatus utilize separate chambers for melting and casting in which the pressure in each chamber can be varied relative to each other in order to introduce molten metal into the mold.

Method and apparatus for compacting support particulates media around ceramic shell molds and around fugitive patterns wherein the mold or pattern is placed in a container and the container is filled with support particulates media. The container is set to rotating and vibrating while it is tilted. The combination of rotation and tilting cause voids at the wall of the mold or pattern to be constantly and methodically reoriented so that the free surface of the support media in the voids is moved past its dynamic angle of repose and is caused to flow into those voids by the combined action of the vibration and the constantly changing orientation of the voids relative to the gravity vector.
