Abstract (en)
[origin: WO2009018902A1] The invention relates to a filler device (1) comprising an exterior tube (2) having an extrusion die (3) located therein and a filler piece (4) that is filled with a metal powder mixture in the intermediate space (8) formed between the filler piece (4) and the extrusion die (3), whereupon said intermediate space is closed. In order to compact the metal powder, the filler device (1) is placed in a hydrostatic pressing system and the metal powder mixture is pressed into a green preform. The pressed tubes are subsequently sintered in one or more passes through a furnace, for which purpose the pressed tubes are subjected to a preselected time/temperature progression so as to ensure that a melt of tungsten (W) forms and contracts evenly in all directions such that a geometrically desired solid body results after sintering.
