  • Publication number: 20130283882
    Abstract: The invention relates to a method and an installation for producing a component from sheet magnesium, comprising a forming tool, which comprises a punch and a die, for forming a semi-finished product made of sheet magnesium, in particular a semi-finished product in the form of a sheet magnesium blank, and a device for heating the semi-finished product to an elevated temperature, preferably to a temperature of at least 200° C., prior to the forming. In order to reduce the component costs, the invention proposes that the forming tool is designed without an internal heat source, is provided with a semi-finished product holder on which the heated semi-finished product can be placed in the forming tool without direct contact with the punch and the die, and comprises a drive which brings about a closing speed of the punch and the die in the range of 15 mm/s to 500 mm/s.
