Abstract
A method of supporting a part with particulate shape retaining media, the method including placing the part on a bed of the particulate shape retaining media, fluidizing the particulate shape retaining media until the part penetrates therein, and vibrating the bed of particulate shape retaining media to compact the particulate shape retaining media around the part. The part may be a green part to be debound in a powder injection molding process. Fluidization may be performed through vibrations at a different frequency than the compaction.
