Abstract
The present invention relates to a method of manufacturing formed aluminum components. The method comprises the steps: i. Providing a hollow profile of aluminum or aluminum allow, the profile having a predetermined length and comprising an outer wall having a pre-determined thickness; ii. Placing a hollow aluminum profile in a cavity of a bending tool and press bending the profile using the bending tool; and iii. Transferring the profile to a cavity of a forming tool and subjecting the interior of the profile to elevated gas pressure, whereby the section of the profile is distended until the outer wall of the profile abuts the forming tool, thereby providing a formed aluminum component; wherein the steps ii. and iii. are performed at a tool temperature of 350-470° C. The present invention further relates to formed aluminum components manufactured by such a method.
