Vacuum Hot Press
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.
