ABSTRACT:
This invention relates to a system and method for loading a plurality of powder materials into a magnetic compaction tool. The system and method employ a powder loader which guides the plurality of powder materials into predetermined locations in the magnetic compaction tool so that when the tool is electromagnetically energized, the plurality of powder materials are compacted to form a part having a plurality of densified metals formed by the plurality of powder materials.
