Abstract

In the manufacture of parts made of compacted powder, the compacting chamber (2) of a die (1) is first filled completely with powder to be compacted between a pair of punches (3 & 4) and before the compacting operation part of the powder is expelled from the chamber by means of a movable core (6) corresponding in shape to a transverse hole or recess to be formed in the part. After compacting, the core is withdrawn from the chamber to allow ejection of the compressed part e.g. by the bottom punch. <IMAGE>
