A METHOD FOR HYDROSTATICALLY COMPACTING METAL POWDER COMPRISING POSITIONING SAID METAL POWER WITHIN A FLEXIBLE CONTAINER IN A DESIRED SHAPE, SUSPENDING SAID CONTAINER IN A CYLINDRICAL PRESSURE CHAMBER DEFINED BY WALLS IN A RECEPTACLE HAVING A GENERALLY CONICAL OUTER WALL, DRIVING A CYLINDRICAL PISTON INTO SAID CHAMBER TO EXERT A SUFFICIENT PRESSURE ON FLUID TO COMPACT SAID METAL POWDER WITHIN SAID CONTAINER, AND SIMULTANEOUSLY EXERTING A PRESSURE ON SAID OUTER CONICAL WALL OF SAID RECEPTACLE BY WEDGING SAID RECEPTACLE DOWN INTO A CONICAL BORE OF A RETAINING BLOCK BY THE FORCE OF SAID PISTON SO THAT THE PRESSURES ON SAID OUTER CONICAL WALL OF SAID RECEPTACLE AND SAID CHAMBER DEFINING WALLS OF SAID RECEPTACLE ARE OFFSET WHEREBY DEFORMATION OF SAID RECEPTACLE IS SUBSTANTIALLY PREVENTED AND A FLUID-TIGHT SEAL IS MAINTAINED BETWEEN SAID PISTON ANS SAID PRESSURE CHAMBER.
