Abstract:
A method for producing nozzles for injectors of internal combustion engines comprising machining nozzle blanks, each having a cylindrical surface with first and second ends, a flat reference surface at the first end and a nozzle tip projecting from the second end, applying a protective disc onto each flat reference surface, providing a containment tube with a closed first end, sequentially inserting the nozzle blanks into the containment tube and completely filling a space delimited from an outer surface of the nozzle tip of the respective nozzle blank to an inner wall of the containment tube after each insertion, compacting the metal powder, evacuating a second end of the containment tube, hot isostatic pressing the containment tube, cutting the containment tube along cutting sections aligned with the protective discs to form separate sections, and machining the sections to form a metallic coating on each nozzle tip.
