Cold isostatic pressing

Benefits Application & materials Process details

Transmits pressure uniformly in all directions to compact metal, plastic, composite or ceramic powders enclosed in a flexible, sealed container and immersed in a pressure vessel filled with water at ambient temperature.


  • Creates a preform of mechanically pressed powder of high enough density to undergo further manufacturing steps as a solid
  • Allows low packing factor powders to achieve high enough density for encapsulation and HIP
  • Eliminates possibility of contamination by die wall lubricants
  • Forms solid preform without the need of binders.

Application & materials

CIP creates relatively simple shape performs, or compacts, from powders that can then undergo further processing steps as a solid such as encapsulation and HIP to achieve full density. Compactible powders include metals, ceramics, polymers and composites.

Process details

Compacts powders to achieve sufficient “green strength” to permit handling as a solid for future process operations.
