hip-of-cast-partsHot isostatic pressing (HIP) is now a standard procedure for removing cavities from highly-stressed cast parts. Sealed porosity, i.e. closed to the outside: - no collapsing of the surface - no cracking to the surfaceMetallically blank surface, i.e. - no oxidationNo gas in the pores, i.e. - cavities are more suitable than gas pores - no outgas into the pores Prerequisites for the removal of porosity: Typical data:filled with argon 1000-2000 barto ca. 1300 °C HIP autoclavePressurizedcontainerThermal insulationElectricheaterClosing forceof the lid
