Abstract (en)

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.
