Abstract: A method for producing a lightweight sheet-metal component with varying wall thicknesses includes extruding a lightweight metal to form a profile with a non-planar profile cross section, wherein the wall thicknesses of the profile cross section differ from one another in at least two regions, cutting the profile to length into profile pieces, widening the profile pieces, and forming the flattened profile piece into a three-dimensional shaped sheet-metal component, wherein the sheet-metal component has at least two regions with wall thicknesses that are different from one another.

Abstract: A motor vehicle door and a method for producing the motor vehicle door is disclosed having a frame plate coupled to reinforcement components and at least half of all of the reinforcement components are produced as extruded profiles which are subsequently press-formed three-dimensionally. The extruded profiles have different wall thicknesses.

Abstract: A hollow structure for installation as cross member or longitudinal member in a motor vehicle includes a hollow member which is made of light metal and has at least one hollow chamber. The hollow member has a wall which is formed with a slot. A flange sized to extend through the slot has a leg configured to rest by a formfit against a side of an inner surface area of the hollow member and at least one area which is coupled to an outer surface area of the hollow member.

Abstract: The present invention relates to a method for producing a lightweight sheet-metal component with varying wall thicknesses, characterized by the following method steps: —extruding a lightweight metal to form a profile with a non-planar profile cross section, wherein the wall thicknesses of the profile cross section differ from one another in at least two regions, —cutting the profile to length into profile pieces, —widening the profile pieces, —forming the flattened profile piece into a three-dimensional shaped sheet-metal component, wherein the sheet-metal component has at least two regions with wall thicknesses that are different from one another.

Abstract: A method for producing an energy-absorbing profile for a motor vehicle includes: providing an extruded hollow profile, the extruded hollow profile having outer walls and at least one inner wall which connects two of the outer walls; inserting a cutting tool into the hollow profile; actuating the cutting tool and cutting an inner wall section out of the inner wall; and removing the cut out wall section and the cutting tool from the hollow profile.
