Hot Isostatic Pressing (HIP)

Our service – compression to the highest degree

Hot Isostatic Pressing (HIP) is a manufacturing technology which is used under high pressure and high temperature, leading to both an increased density and overall improvement of the 
materials properties. 

Materials that do not sinter to the required density in conventional sintering units can be further compressed to the highest maximum using our Hot isostatic presses (HIPing). Two units are available at QSIL for this purpose. Depending on the material, we have the facilities to treat 
components ranging in the size from very large to very small.

Typical fields of application:

  • Sputtering targets for thin-film technology 
  • High-strength composites for wear components
  • Materials for indexable inserts and HSS cutters
  • Binder-free hard materials and refractory metals
  • Diffusion-bonds
  • Reduction of residual porosity 
  • Achieving of transparent media
  • Densification of non-ferrous metals (aluminium) / 3D printed
  • Compaction of ferrous materials


With our cold isostatic and uniaxial presses, we can compact pressed granules into semi-finished and finished parts. Even very large components are no problem for us.
