Abstract
An improved method is disclosed for encasing an object in a shell or layer of outer material. The encased object and the outer material are formed from sinterable metal or ceramic particulate material. Both the object to be encased and the shell or encasement are formed by extrusion. Novel methods are disclosed by which the object and the outer material can be simultaneously formed by co-extruding the sinterable particulate materials, or by extruding the outer layer onto a formed object using the die assembly of the invention.
