The present invention relates to a process for producing a wiper arm for a window wiper device for a motor vehicle, with an upper arm portion, on which a mount is provided, in order to fix the wiper arm detachably to a wiper drive of the window wiper device, and a lower arm portion, which is pivotably connected to the upper arm portion, as well as at least one wiper blade holder which is pivotably connected to the lower arm portion, characterized by producing the wiper arm in a multi-component injection-molding process in which, in a first process step, the upper arm portion is injection-molded along with at least one first pivot pin formed on it by means of a first material component in a partial portion of a cavity, in a second process step the lower arm portion, pivotably connected to the upper arm portion, is injection-molded along with at least one second pivot pin formed on it by means of a second material component in a second partial portion of the cavity by encapsulation of the first pivot pin, and in a further process step at least one wiper blade holder is injection-molded by means of a third material component in a further partial portion of the cavity by encapsulation of the second pivot pin.
