The invention relates to a method for producing a squirrel-cage rotor (4) of an asynchronous machine (1), comprising the following steps: providing a substantially cylindrical magnetizer, in particular a rotor lamination stack (5), having a substantially axially extending recess (14), inserting a conductor rod (6) made of a first conductive material (13) into the recess (8), the conductor bars (6) are arranged on the conductor bars (6) in such a way that the conductor bars (6) protrude from the end faces (20) of the magnetizer, in particular of the rotor lamination pack (5), so that at least one projection (23) is formed on one side, in particular on each of the two sides, providing a short-circuit disk (7) made of a second conductive material (14) having a radially outwardly open recess (9), at least one shorting disk (7) is axially positioned on a projection of a corresponding conductor bar (6) projecting from an end face of the magnetizer, in particular of the rotor laminated core (5), and the axially tran
