Method of forming articles from ductile materials

Claim 1

THE METHOD OF MAKING OBJECTS OF MAXIMUM DENSITY OF MATERIAL AND IN SELECTED SHAPES AND ALL OF THE SAME UNIFORM, ACCURATE, DIMENSIONS, WHICH COMPRISES: (A) CONFINING THE SIDES AND ONE END OF A BODY DUCTILE METAL TO WITHSTAND HIGH PRESSURES WHILE UNSOFTENED BY ADDED HEAT ABOVE ROOM TEMPERATURE, WITH SAID ONE END OF SAID BODY ABUTTING FACE TO FACE DIRECTLY AGBAINST A CONFINED, RELATIVELY INCOMPRESSIBLE ELASTOMERIC ELEMENT OF SUBSTANTIAL THICKNESS THAT IS DEFORMABLE WITHOUT ADDED HEAT UNDER PRESSURE, AND (B) WHILE SAID BODY AND ELEMENT ARE SO CONFINED, AND AT A TEMPERATURE BELOW THAT WHICH WOULD MATERIALLY INCREASE THE FLUIDITY OF THE METAL BODY, PENETRATING THE UNCONFINED END WALL OF SAID BODY WITH A FORMING TOOL, HAVING A DESIRED CONFIGURATION ON ITS SIDES AND ADVANCING END WALL, AND THEREBY DISPLACING SOME OF SAID DUCTILE METAL BY COLD FLOW DISPLACEMENT AROUND AND AGAINST THE SIDE OF SAID TOOL AS IT PENETRATES SAID BODY, WHICH IN TURN CAUSES SAID ELASTOMERIC MATERIAL TO APPLY A RESULTANT UPWARD COMPONENT FORCE TO THE PERIPHERAL PORTIONS OF SAID SLUG TO AUGMENT SAID COLD PLASTIC DISPLACEMENT, AND THEN (C) SEPARATING SAID TOOL AND DEFORMED METAL BODY.
