Abstract (en)
[origin: WO2017016778A1] A method for producing a nozzle body (1) for a fluid injection valve comprises provision of a nozzle body blank with a nozzle body tip (20) and introduction of a nozzle body recess (7), starting from a first axial end (3), into the nozzle body blank and, as a result, formation of a wall (9). Furthermore, the method comprises provision of geometry data of at least one injection hole (17) to be provided, with an inner opening (18) and an outer opening (19). Furthermore, the method comprises determining a height (H) of a blind hole stage (15) of a blind hole (13) to be formed in a manner which is dependent on a predefined fluid penetration. Furthermore, the method comprises adaptation of a part of the shape of an inner face of the wall (9) and, as a result, formation of the blind hole (13) with the blind hole stage (15) at the determined height (H), and introduction of the at least one injection hole (17) with the provided geometry data, with the result that the at least one injection hole (17) penetrates the wall (9).
