ABSTRACT:
An apparatus and method for compacting powder material into a prismatic or pyramidal article in a molding cavity formed by the end face of a lower punch reciprocable in a die bore, a portion of the die bore and the end faces of a pair of telescopic concentric punches being disposed above the die bore. The lower punch end face forms an end surface of the prismatic or pyramidal article, the die bore wall forms the peripheral surface of the article, and the upper telescopic punches form the other end surface of the article, one of the telescopic punches being disposed peripherally to the other punch and forming a sharp edge between the peripheral surface of the article and its other end surface.
