With this sintering method the tool respectively the component is heated directly by DC current pulses so that cycle times of few minutes will be possible. The use of DC current pulses leads to an additional increase of the sintering activity with many materials, resulting from the processes that occur on the points of contact of the powder particles (Joule heating, generation of plasma, electromigration etc.). Therefore significantly lower temperatures as well as significantly lower mould pressure than at conventional hot pressing and sintering will be possible.

Available pressing force: 12.5 to 4000 kN at max. 2400 °C, applicable for components of max. Ø 300 mm. This leads to absolutely new possibilities of producing a lot of materials with extraordinary attributes, for example:

  • Nanomaterials can be sintered without significant grain growth.
  • FGM („Functionally Graded Materials“)
  • composite materials
  • innovative cemented carbide materials
  • aluminium or copper alloys and intermetallics
  • structural and functional ceramics
