Abstract
An arrangement for producing a blank made of metal powder, preferably titanium powder, intended for a dental crown or other product for the human body (spacer, dentine, implant, etc.) comprises at least one first apparatus for powder compression and at least one second apparatus with one or more elastic molds having at least one cavity for a punch (block) and the powder used in the initial stage. The first apparatus comprises a machine operating by impact compaction, and said mold or molds is/are arranged, when the cavity is filled with starting powder, to receive impacts effected by the impaction members in the machine and, as a function of the impact or impacts, to generate an isostatic action during the compression/compaction. The invention also relates to a device, method and use and permits a rapid production procedure while maintaining the current requirements in respect of precision and quality.
