Claim:
A hot runner nozzle which can be coupled to an injection molding tool, the hot runner nozzle comprising: a housing having at least one nozzle duct extending laterally through the housing, the nozzle duct terminating in a nozzle tip; a heater disposed adjacent to and extending parallel with the nozzle duct and for temperature-controlling the nozzle duct; at least one material recess located between the heater and the nozzle duct, wherein the material recess is at least one longitudinal slot which runs in the longitudinal direction of the housing which divides the housing adjacent to the nozzle duct into housing regions, which are longitudinally spaced apart from one another, wherein the material recess further includes at least one transverse slot, which runs transversely to the longitudinal direction of the housing, which divides a heating region of the housing, which accommodates the heater, between a housing base for connecting to the injection molding tool and a housing head for accommodating the nozzle tip into at least two partial heating regions, which are axially separated from one another.
