Using additive manufacturing techniques, a wide range of metal powders can be hot iso-statically pressed (Fe, Ni, Co, Ti, Cu, Mg, Al) for manufacture for metal components.

While Hot Isostatic Pressing is used to eliminate pores in metal components, it can also be used for the consolidation of powder and diffusion bonding of dissimilar metals or alloys. The powder is canned in capsules of suitable material, which are produced by sheet metal forming and welding. The capsule is designed to give the fully dense end product the desired shape.

Key Benefits:
  • Improved quality and performance due to fine and isotropic micro-structures
  • Design flexibility, Near-Net shapes, Net shapes or Bimetal construction
  • Reduction of number of welds on complex parts
  • Reduction of machining requirements
  • Less NDT needed & easier NDT
  • Dense, without segregation
  • Use of composite materials
  • Freedom of part sizes and production series and choice of alloys
  • A lean manufacturing route, leading to shorter production lead-times
  • Producing single parts where previously several were required
  • Cost reduction
Process Attributes:
  • A wide range of metal powders can be hot iso-statically pressed (Fe, Ni, Co, Ti, Cu)
  • New alloy compositions which were impossible to cast or forge can be considered
  • During hot iso-static pressing, the elements do not have time to segregate, because the temperature is below the melting point
