Abstract

The tool has a die part (40) of limited flexible plastic material, which is inserted into, and seals the profile chamber (12) of a hollow profile or component (10). An additional tool element (54) of a high strength material is positioned around the flexible part and engages on the hollow profile when the tool is moved into operational position. The die part is cup-shaped with base plate (42) and wall (44), it consists esp. of polyurethane, and is connected to a metal die (16). The additional tool element is of a metal material, containing pref. mainly iron, and a carbon proportion of no more than 2%.
