Abstract

The invention for working extruded profile sections with respect to the outer contours thereof by way of hot shaping and/or hot stamping and/or cutting operations and/or punching operations comprises the following method steps: —inserting the profile sections (1) heated to a temperature in the range of 250 to 450° C. into a two-part shaping tool (2) preheated to a temperature of 300 to 600° C.; and —applying pressure to the shaping tool (2) by way of one or more pressing cylinders (3) of a press (4). The device for carrying out the method comprises a press (4) and a shaping tool, wherein the shaping tool (2) is formed of two tool halves I, II, which are displaceable with respect to each other, and between which the profile section (1) is inserted.
