Zusammenfassung:	A method and apparatus for loading tool steel and high speed steel powder to a deformable mold for compacting is disclosed. The particles are exposed to a uniform vacuum during transfer from a sealed container through a sealed conduit and into a sealed deformable mold. By this method and apparatus, the particles are uniform throughout the container and substantially free of impurities, without requiring conventional outgassing.
