Hot Isostatic Pressing (HIP)
Hot Isostatic Pressing is used to densify powders or cast and sintered parts at high pressure and at temperatures from 900 °C to 1,250 °C for example for steels and superalloys. The Hot Isostatic Pressing process provides improved stability and mechanical properties of solid parts due to the fine and homogeneous isotropic microstructure. Furthermore Hot Isostatic Pressing permits the use of composite materials and the creation of large and complex shaped components from powders.
It is very complementary to other powder metallurgy processes such as Metal Injection Molding (MIM), pressing and sintering, or Additive Manufacturing technologies. The application areas are broad, ranging from offshore applications to aviation, tooling and electronics.
