HIP – Hot Isostatic Pressing: Hot isostatic pressing (HIP) is a manufacturing process used to eliminate porosity in metals and increase the density of many materials. This improves the material’s mechanical properties (fatigue strength, ductility, impact resistance) and machinability; in other words, the HIP process significantly enhances the safety of the component.When components are treated using the HIP process, the simultaneous application of heat and pressure eliminates internal voids and micro-porosities through a combination of plastic deformation, flow and diffusion bonding of the material.The HIP process is used to significantly improve the technical properties of, for example, castings, additively manufactured products, tools, motorsport components and aerospace components.

Powder metallurgy: Powder metallurgy deals with the production of metal powders and their further processing. When combining PM and HIP, a powder is filled into a welded capsule. The capsule is welded as close to the final contour as possible to enable optimal use of the raw material ‘powder’ and to work in a resource-efficient manner. After filling, the capsule is sealed under vacuum and densified into a component via the HIP (Hot Isostatic Pressing) process, which serves as the basis for the further processing of the finished part.
