Abstract
Metal sheets () are produced from strand-shaped profiles () having a low thickness, made of magnesium or magnesium alloys by way of an extrusion system (). The open or closed extruded profile () exiting the extrusion die (-) of an extrusion press () is shaped to obtain a flat metal sheet () and is then subjected to a defined shaping process by way of stretch-forming. The system for carrying out the method is essentially composed of an extrusion press () comprising a die plate generating the extruded profile and a shaping unit () following the die plate, wherein the shaping unit () is composed of a severing unit (), a bending unit (), and an unrolling unit ().
