Abstract
Compaction is the central stage of the Powder Metall shaping process. Powder blends must balance free flow with high green strength and good compressibility (of special interest to powder makers); tooling must be of sufficient strength to withstand the stresses of production, and must incorporate design features that take into account not only finished-part geometry but also die fill, powder-transfer stages, press kinematics and ejection to achieve uniform pressed density and to avoid generation of shear or tensile cracks as a result of the compaction process (of special interest to tool designers and press makers).
