Abstract: A method for producing an injector which is designed in particular to inject fuel into an induction pipe or directly into a combustion chamber of an internal combustion engine. The method includes providing an injector base element, providing a rod that is insertible into a through hole of the injector base element, producing a negative matrix of a spray orifice element on an axial end of the rod, inserting the rod into the through hole of the injector base element, positioning the negative matrix situated on the rod relative to the injector base element, producing the spray orifice element having at least one spray orifice by applying a galvanization layer on a downstream end, in the injection direction, of the injector base element and on the negative matrix, and removing the rod and the negative matrix.

Abstract: A turbine wheel includes, a hub body, a plurality of turbine blades integrally formed with the hub body, and a shroud. The shroud encompasses the hub body, is integrally formed with the turbine blades, and interconnects the respective radial outer edges of the turbine blades. A method of producing the turbine wheel in one piece via primary forming includes applying a layer of powdered material having a predetermined layer thickness to a construction platform, selectively melting the layer of powdered material with reference to a current layer form of the turbine wheel, moving the construction platform by a predetermined amount, and repeating applying, selective melting, and moving until a last layer of the turbine wheel is formed.
