摘要：
The invention relates to a method for manufacturing a fuel injector for an internal combustion engine that has a control valve, which opens or closes an outlet throttle from a control chamber and in which a closing element is moved into a valve seat in order to close the outlet throttle. The valve seat is produced by punch-forming using a forming punch. The invention also relates to a fuel injector that is manufactured in accordance with this method.
