Hot Isostatic Pressing (HIP)

Hot Isostatic Pressing (HIP)

HIP has established itself in the past decade as a competitive and proven manufacturing process for the production of complex and highly specified components made from a wide range of metals. These components are currently being used in a number of industry sectors that have highly demanding environments for example: aerospace, offshore, energy and medical.

HIP is a process to densify powders or cast and sintered parts in a furnace at high pressure (100-200 MPa) and at temperature from 900 to 1250°C for example for steels and superalloys. The gas pressure acts uniformly in all directions to provide isotropic properties and 100% densification. This technology is very complementary to other powder metallurgy (PM) processes such MIM technology, pressing and sintering, or the new additive manufacturing technologies.

Even, it is used in combination with these PM processes for part densification and the production of semi-finished bars or slabs. A wide range of component types can be manufactured thanks to HIP. It has developed over the years to become a high-performance high-quality and cost-effective process for the production of many metal (or ceramic) components.
