ABSTRACT:
A steel core (16) is subjected to an anti-adhesion passivation treatment. The nozzle (10) is then deposited by electroforming on the core of a layer of metal of predetermined thickness. After the tip (13) of the electroformed nozzle has been faced to uncover the capillary hole, the core (16) is extracted with an apparatus which comprises a plate for retaining the print nozzle and an extraction gripper. The electroforming bath may be formed by a solution comprising nickel salts.
