Process Description

The interaction of the HIP process and equipment must be understood to help explain the technology. There are two basic types of autoclave used for HIP. The first is known as a hot-loading cold-wall vessel where the parts to be densified are heated to the HIP temperature external to the high-pressure chamber. The second type is known as a cold-loading cold-wall vessel where the parts and furnace enter the high-pressure chamber at room temperature and are sealed in place. The heating and pressurizing of the parts and the vessel are then done according to a preprogrammed set of parameters.
