Abstract (en)
[origin: WO2014187442A1] Metal sheets (13) are produced from thin-gauge billet-type sections (8) consisting of magnesium or magnesium alloys, by means of an extrusion facility (1). The open or closed extrusion section (8) exiting the extrusion die (6-7) of an extruder (1) is formed into a uniform sheet (13) and subsequently subjected to a defined forming process by drawing. The facility for carrying out the method consists substantially of an extruder (1) with a die that produces the extruded section and of a forming unit (5) adjoining the die. The forming unit (5) is composed of a separation unit (2), a bending unit (3) and an unfurling unit (4).
