Why cold form?
One of the major benefits of cold forming is work hardening. This strength increase allows the thinning down of equivalent stamping or forging cross sections, saving weight while not impacting strength. Alternatively, for the same packaging constraints, a stronger part can be produced.
This work hardening can also allow the elimination of hardening heat treatments. Part surface quality is such that often the surfaces can be used as-formed. Cold forming allows variable part cross-sections. This, in-turn, provides opportunities for part consolidation.
