Cold isostatic pressing applies pressure from multiple directions for achieving greater uniformity of compaction (high-quality parts) and increased shape capability, compared to uniaxial pressing.
Cold Isostatic Pressing
Cold isostatic pressing applies pressure from multiple directions for achieving greater uniformity of compaction (high-quality parts) and increased shape capability, compared to uniaxial pressing.
There are two methods of carrying out isostatic pressing.
In wet-bag isostatic pressing, powder is encased in a rubber sheath that is immersed in a liquid which transmits the pressure uniformly to the powder.
In dry-bag isostatic pressing, rather than immerse the tooling in a fluid, the tooling itself is built with internal channels into which high-pressure fluid is pumped.
