Abstract: The method of diffusion molding cubically-shaped metal granules into a workpiece comprises cleaning the granules, depositing them into the cavity of a tooling mold, vibrating the tooling mold to orient the interfaces of the cubical granules into alignment with one another, encapsulating the tooling mold in a sealed enclosure, evacuating the enclosure, applying heat and pressure to the enclosure to effect diffusion molding of the granules into a workpiece configuration, and removing the workpiece from the enclosure and reusable tooling mold.

Abstract: An apparatus for diffusion molding cubical granules of metal into a workpiece. Tooling is assembled to form the shape of a mold cavity which contains the cubically-shaped metal granules to be diffusion molded. Collapsible supports space the tooling from the interior walls of an envelope containing the tooling. Pressure bars, slidably engaged with the walls of the mold cavity, transmit compressive force applied on the envelope to the metallic granules. The envelope is sealed and evacuated to facilitate oxide and contaminate-free diffusion molding. The method for diffusion molding cubically shaped metal granules into a workpiece comprises cleaning the granules, depositing them into the cavity of a tooling mold, vibrating the tooling mold to orient the interfaces of the cubical granules into alignment with one another, encapsulating the tooling mold in a sealed enclosure, evacuating the enclosure, applying heat and pressure to the enclosure to effect diffusion molding of the granules into a workpiece configuration, and removing the workpiece from the enclosure and reusable tooling mold.
