Hot Isostatic Pressing (HIP) is a development in manufacturing technology in which powders and solids, especially ceramics and metals, are hot pressed and sintered simultaneously.
The component is inserted into a deformable, sealed container. This container is placed in a heatable pressure vessel and the component is compressed under protective gas at temperatures of up to 2000 °C and pressures of 100 to 200 MPa. The gas pressure acts on the workpiece from all directions, giving the component isotropic properties. Open pores cannot be compacted further, as the gas would penetrate into these pores. Recompaction is only possible when the pores are closed.
The components manufactured in this way are very dense and have isotropic properties. A major disadvantage of this technology is the very high manufacturing costs, especially with low dimensional tolerances. The main areas of application are post-compaction of sintered metal and ceramic workpieces for the aerospace, automotive industry or medical implants.
