Abstract
A method and apparatus are disclosed for producing a powder metal part having a plurality of cavities. The method involves introducing a metal powder and an apparatus into a mold, the apparatus being made of a plurality of solid pieces which are in the shape of the cavities to be formed. The pieces are joined together by joining means and are positioned relative to each other by adjusting means so that the cavities formed therefrom are equally spaced about the center of the part. The apparatus is then removed from the mold, and the powder is then isostatically pressed in the mold to produce a green part which is then sintered to form the final part having the cavities.
