A method of operating a hot-chamber diecasting machine is provided in which, after the filling of the mold, a compressional vibration is generated which prevents the molten metal from rapidly solidifying at least in the narrowest cross-section of the feed orifice between the ascending bore and the mouthpiece and the mold. In this manner, it becomes possible to increase the afterpressure upon the molten metal in the mold in comparison to conventional hot-chamber diecasting processes in order to achieve cast parts of a higher quality.
