ABSTRACT:
Sintering method and apparatus. A pre-sintered or compacted mass of particulate material is densified by loading the mass into a substantially closed three-dimensional space defined by three pairs of punches juxtaposed thereacross in three respective directions, and then by multi-axially compressing the mass by advancing the punches of each pair toward each other while energizing the mass with thermal energy. The axes of action of pressures applied thereto by the three pairs of punches intersect substantially at a point substantially constituting the center of the three-dimensional space.
