Abstract
A closure panel forming and assembly process includes inputting partially stamped inner and outer panels into the assembly system and finished assemblies out. The invention is a manufacturing process for closure panel assemblies, doors, deck lids, hoods, liftgates and other similar panels. The process has a reduced stamping operation of only two die stages, with the first operation being a draw operation followed by a second operation of trim and pierce. These operations may be done at a satellite location which may be within the same facility or at an outside location. All additional metal forming operations are done at an assembly system.
