Beschreibung
Zusammenfassung:	In a process for the manufacture of a shaped bar consisting of an at least partially metallic material, a preform is shaped to form the shaped bar in the partially solid/partially liquid state and the shaped bar in the partially solid/partially liquid state is guided through a chilled mould for setting. An optionally heatable preform chamber is provided for receiving the preform, an optionally heatable forming chamber is connected to the preform chamber for shaping the preform to form the shaped bar, and a chilled mold is connected to the forming chamber for the setting of the shaped bar. A die can optionally be arranged immediately downstream of the mould for the final shaping process and the device.
