Abstract

A process for forming closed sections using electromagnetic force. A sheet metal stock is folded into a generally closed section having flanges. The folded section is placed in a die and the die is closed. An electromagnetic force is applied to the die to expand the sheet metal towards interior walls of the die, thereby forming the closed section to a predetermined shape. During expansion, the flanges are drawn inward toward the die. After removed from the die, excess flanges are trimmed from the section if needed, the sections welded closed.
