Powder Metallurgy (PM/HIP)
Powder Metallurgy

Powder metallurgy (PM/HIP) involves the production of metal powders and their subsequent processing. When combining PM and HIP, a powder is filled into a welded capsule. The capsule is welded as close to the final shape as possible to enable optimal use of the “powder” raw material and to ensure resource-efficient operation. After filling, the capsule is sealed under vacuum and densified into a component using the HIP (Hot Isostatic Pressing) process, which serves for the further processing of the finished part.

When components are treated with the HIP process, internal voids and micro-porosities are eliminated through the simultaneous application of heat and pressure, using a combination of plastic deformation, creep, and diffusion bonding of the material. The powder is thus compacted into a solid material.

PM/HIP process chain

The PM/HIP process comprises several precisely coordinated steps. This process sequence enables complex components with high dimensional accuracy and density—without conventional casting or milling.

Capsule construction, powder, consolidation

  • Capsule construction: Design of gas-tight shells based on a 3D model
  • Powder filling: Selection & charging of qualified metal powders
  • Evacuation & sealing: Geometries welded under vacuum
  • Hot Isostatic Pressing: Consolidation at temperature & pressure
  • Unpacking & finish: Removal of the shell and post-processing if necessary

Economic efficiency

Material, cycle time, machining effort

Compared to classic machining or casting technology, PM/HIP offers decisive economic advantages. An assessment of your components will show whether PM/HIP is also economically viable for your project.

  • Material savings: Up to 90% less removal
  • Reduced effort: Fewer processing steps
  • Calculable cycle times: Through batching & planning reliability
  • Higher output: Ideal for series with constant demand

Powder Metallurgy for
series production

PM/HIP is ideal for series components in safety-critical industries—wherever repeatability, process control, and documented quality are required. The combination of a defined capsule, controlled powder, and a standardized HIP process makes reproducible results the norm.

Quality certificates & standards

Example applications

All PM/HIP processes at OWL are carried out on the basis of relevant standards:

  • EN/AS 9100, ISO 9001 – Quality management
