ABSTRACT:
The present invention provides a method and apparatus for powder metal formation in which a plated shell is formed corresponding to the appropriate calculated pre press size of the final part being formed; the electroplate shell is filled with powder metal to be formed; the shell is surrounded by a pressure transferring support media and compacted using a suitable force transmitter such as an isostatic press; and the support media is removed leaving the final product within the electroplate shell which may or may not be removed as desired.
