During Hot Isostatic Pressing (HIP), the material to be processed is heated up in special plants (HIP plants) under argon atmosphere, high gas pressure and under high temperatures exceeding the yield point in order to compact the component. For most materials, the process pressure is approx. 1000bar = 100MPa and temperatures are up to 1400°C. The aim of the HIP process is to remove internal cavities, e.g. residual pores in cast or sintered metal or ceramic parts, in order to obtain properties comparable to those of forged materials.
During cold isostatic pressing, any desired object (powder-filled elastic moulds) are compacted isostatically (i.e. from all sides) by means of an effective pressure medium. Thus, the compacted material is homogeneous and has a high density.
