Hot Isostatic Pressing (HIP)
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, creep 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.
How it works & process steps
(HIP-Cycle)
In the HIP process, components are subjected to temperatures of up to 1350 °C and pressures of up to 2000 bar. This combination of processes closes internal pores. OWL GmbH uses state-of-the-art HIP systems with validated temperature and pressure control to ensure reproducible processes.

OWL GmbH is certified for the hot isostatic pressing of metal products and the sintering of metals, ceramics and powders
Costs & Lead Times
The costs and lead times associated with the HIP process are influenced by a number of factors. In addition to the properties of the component, the choice of material, production conditions and specific testing and documentation requirements play a decisive role. Grouping orders with the same process parameters reduces costs and shortens lead times.
