Cold Isostatic Pressing (CIP) is a method of compacting powders into green bodies and near-net shaped in a pressure vessel. The powder, which can be metallic, ceramic or graphite, is sealed in a flexible mold shaped like the end product. High pressure is used up to 600 MPa (6,000 bar/87,000 psi) having water as pressure medium. A high and uniform density is achieved, resulting in easier handling, easier machining and even predictable shrinking during sintering.

CIP applications include compaction of powders into refractory nozzles, metal filters, graphite parts, ceramics, cemented carbides, etc.
