Vacuum Hot Press

Hot pressing has a limited field of application for such materials which do not sinter to high densities due to low diffusion coefficients or for cases where a pore-free state is required (for optimum mechanical, thermal or optical properties).
With this process only parts with simple shapes like plates, blocks, cylinders can be manufactured easily. With a highly sophisticated design of pressing dies also more complex shapes can be produced.
Available pressing force: 50 kN to 9000 kN at max. 2500°C, applicable for components of max. Ø 700mm.

Application of hot pressing in the field of ceramics include:

  • Silicon nitride, mixed ceramics of Al2O3, TiC/TiN and sialon for cutting tools, components of heavy-duty valves, bearings, wear parts for process technology.
  • PLZT (lead-lanthan-zircon-titanate) and other high developed functional ceramic (O2 atmosphere)
  • Boron carbide (B4C) for extremely wear resistant parts and armors.
  • SiC whisker reinforced Al2O3 for cutting tools
  • MMC and CMC materials, composite materials
  • Sputter targets

Hotpressing technology is applied variously in fundamental research and production.
