Abstract
A method and tool for forming a hem flange pre-hem and a final hem on a sheet metal panel wherein elastomeric tooling elements are used to apply radial compression during a forming operation. The elastomeric tooling elements are compressed and apply pressure to a side of the sheet metal panel, for example an aluminum panel, that is stretched during a forming process step. A foil layer may be placed between the sheet metal blank and the elastomeric tooling element to reduce friction and further improve forming performance.
