In the production of a nozzle cartridge with a nozzle formed thereon in a hollow mold, in which a core (,) is located, a centering of the core (,) occurs in an injection phase by utilizing webs (,) provided on the hollow mold, with a conical centering surface (,) of the core (,) abutting against them. In a subsequent supplementary filling phase, the core (,) or an interior core (,) is withdrawn, the melt flowing over the webs (,) and forming a closed wall in the area of the nozzle base.

Method for producing a nozzle cartridge

In the production of a nozzle cartridge with a nozzle formed thereon in a hollow mold, in which a core (26) is located, a centering of the core (26) occurs in an injection phase by means of webs (40) provided on the hollow mold, with a conical centering surface (39) of the core (26) abutting against them. In a subsequent supplementary filling phase, the core (26) or an interior core (28) is withdrawn, the melt flowing over the webs (40) and forming a closed wall in the area of the nozzle base.
