Hot Isostatic Pressing (HIP)

This process is used to produce full density parts with great mechanical properties even with the finest materials.

The hot isostatic pressing process combines high temperature (up to 2200ºC) and isostatic inert gas pressure (from to 100 to 3100 bar) in a high pressure containment vessel. Heat and pressure, applied simultaneously, eliminate internal voids and residual porosity therefore improving fatigue resistance of fabricated parts and resulting in a very fine grained structure.


  • Great flexibility in the design, chemical composition, particle size distributions used and form
  • Increases material properties such as resistance to stress, cracking and corrosion and removes air bubbles
  • Allows manufacturing with irregular shapes and complex geometries
  • Creates uniformity of properties in all directions (isotropic)
  • Reduction of costly operations like machining and welding
  • Improves process safety by the elimination of critical welds
  • Possibility of graded structures (solid/powder) with perfect bonds between the layers
