  • Publication number: 20240367728
    Abstract: A method for manufacturing a motor vehicle structural component from an extruded multichamber hollow profile. The method includes providing an extruded profile with at least two precursor hollow chambers which are separated from one another by an inner wall, wherein in at least one outer wall of at least one precursor hollow chamber in cross-section perpendicularly to a longitudinal extent of the extruded profile has a region with non-linear course. The extruded profile is formed in at least one of its end regions into the motor vehicle structural component, wherein at least the region with non-linear course of the at least one outer wall of the at least one precursor hollow chamber, with non-linear course in cross-section, is at least partially straightened, with a change in cross-section of the respective precursor hollow chamber into the cross-section of the corresponding hollow chamber of the motor vehicle structural component.
