Abstract

A cold isostatic pressing method and apparatus using fluid pressure to compact a material charge held in a flexible mold, including a hard die placed inside the mold, the die defining a receiver which has a longitudinal axis, at least one tooling member and a material charge placed in the receiver, such that when the hard die, tooling member and charge are sealed in the mold, pressure applied to the sealed mold will force the tooling member and the charge together to cause uniaxial compaction of the charge in the receiver along the longitudinal axis of the receiver. Preferably the charge is compacted between at least two tooling members. The charge also may be simultaneously compacted transverse to the longitudinal axis by a lateral tooling member.
