| Isostatic pressing involves the compaction of metal or ceramic powders under hydrostatic pressure. The "green" components so formed then require sintering to diffusion bond the powder particles and achieve the required final material density. The pressing process may be carried out low temperatures, cold isostatic pressing-CIP, or at a high temperature at which sintering can also occur, hot isostatic pressing - HIP | ||||||||||

| The
diagram illustrates these two processes. In both case the component is
formed to near net shape and the final sintered product will have relatively
low porosity.
