Hot Isostatic Pressing – is a manufacturing process used to reduce porosity and shrinkage and improve the density of metal castings, resulting in improved mechanical properties. The HIP process is also used extensively to produce components from powder. In powder metallurgy, HIP uses high temperatures and high pressures to convert the powder into a solid shape. The output of the powder metallurgy HIP process is a near net shape: that is, a component that is very near to its final, finished size and shape, requiring a minimal amount of subsequent finishing processes, such as machining.

The powder metallurgy HIP process has many benefits. It allows the production of complex shapes without the need for welds. The metallurgical structure is of fine, uniform grains that provide good mechanical properties with reduced variability. The fine grains also facilitate ultrasonic inspection.
