FAQ Hot Isostatic Pressing (HIP) &
Powder Metallurgy (PM)

Here you will find answers to frequently asked questions about our core processes – Hot Isostatic Pressing (HIP) and Powder Metallurgy (PM/HIP). Whether the issues are technical, procedural or financial, we can provide you with a sound initial assessment.

HIP is a process for the pore-free densification of metallic materials. It involves treating components at high temperatures and under isostatic gas pressure in order to seal internal defects and improve mechanical properties. It is used, amongst other things, in additive manufacturing, casting and for powder metallurgy billets.

Powder metallurgy combined with subsequent HIP enables the production of near-net-shape blanks with high density and dimensional accuracy. By eliminating traditional casting or machining processes, complex components can be manufactured cost-effectively and with consistent quality – making this ideal for series production with constant demand.

The key parameters are:

  • Temperature up to 1350 °C
  • Pressure up to 2000 bar (200 MPa)
  • Dwell Time according to specification
  • Dwell Time according to specification

These parameters have a direct effect on density, grain structure and residual stress, and thus on fatigue strength and dimensional stability.

The costs depend on:

  • Dimensions and weight of the component
  • Material (e.g. Ti6Al4V, Inconel, CoCr)
  • Process complexity and testing requirements
  • Batch size (single item or batching)

A standardised cost calculator is currently in the planning stage – until then, we will provide bespoke quotes on request.

OWL documents all process-critical steps:

  • Material & Batch Allocation
  • HIP Cycle Data, including Temperature & Pressure Chart
  • Test reports (NDT, density, microstructure)
  • Certificate of conformity where required

All data is archived internally and can be retrieved in full on request – as a PDF or in a machine-readable format.
