ABSTRACT:
An apparatus for compacting powder material into a mold cavity formed at least between an upper and a lower reciprocally movable punch. The lower punch reciprocates in the center bore of a die and has an end face defining a portion of the mold cavity. The upper punch is reciprocable so as to be placed over the die bore and has an end face defining another portion of the mold cavity. The upper punch end face is coated with, or made of, an elastomeric material. The upper face of the lower punch may be flat or contoured. The compaction of the powder material in the mold cavity is accomplished by the upward movement of the lower punch which forces the powder material to conform to the configuration of the mold cavity. After compaction, the upper punch is withdrawn and the compacted product is ejected.
