A method for producing a cage rotor for an asynchronous machine is provided. The method includes providing a rotor body having a conductor bar segment in which conductor bars are provided, producing conductor bar slots in the conductor bar segment, wherein one conductor bar slot is provided for each of the conductor bars and producing short circuit ring recesses for short circuit rings, wherein the conductor bar slots each open into the short circuit ring recesses, pressure die casting cage material in the conductor bar slots, in situ, so that the conductor bars are formed of the conductor bar material in the conductor bar slots and the short circuit rings are formed in the short circuit ring recesses, and generating an area in the conductor bar material and the rotor body material including a metallurgical bond between the conductor bar material and the rotor body material at interfaces between the conductor bars and the rotor body.
