Isostatic pressing

What is cold isostatic pressing?

Cold isostatic pressing is a method of compacting powdered materials into a solid homogeneous mass before machining or sintering. Sometimes referred to as hydrostatic pressing, it is a very simple process capable of producing high-integrity billets or preforms that exhibit little distortion or cracking when fired.

What is hot pressing method?

Hot pressing is a high-pressure, low-strain-rate powder metallurgy process for forming of a powder or powder compact at a temperature high enough to induce sintering and creep processes. This is achieved by the simultaneous application of heat and pressure.

What is isostatic pressing in ceramics?

Hot isostatic pressing is a manufacturing process which utilizes elevated temperature and isostatic gas pressure to eliminate porosity and increase density in metals, ceramics, polymers, and composite materials. This improves the material's mechanical properties and potentially workability.

What is isostatic pressing in powder metallurgy?

Isostatic pressing is a powder metallurgy (PM) forming process that applies equal pressure in all directions on a powder compact thus achieving maximum uniformity of density and microstructure without the geometrical limitations of uniaxial pressing.

Why is hot isostatic pressing used?

Hot isostatic pressing (HIP) is a manufacturing process, used to reduce the porosity of metals and increase the density of many ceramic materials. This improves the material's mechanical properties and workability.
