Abstract (en)
[origin: CA2952090A1] The invention relates to a method and to an arrangement for producing open or closed annular structural components made of light metal and alloys thereof, preferably of magnesium or magnesium alloys, having a two- or three-dimensional structure by means of extrusion. The extruded profile emerging from the matrix of the extruder (3) is formed into a helix shape (9) by means of one or more guide tools (5) such that in the area of overlap, the ends of the helical shape (9) are separated from the extruder, and in a calibrating device (7), said helical shape is formed into a two- or three-dimensional structural component (10).
