  Techniques for reducing wall thinning during a hydroforming operationUSPTO Application #: 20070169530Title: Techniques for reducing wall thinning during a hydroforming operation Abstract: It has been found that a compressive force assists in obtaining desired cold flow characteristics of a tubular steel work piece during a hydroforming operation. It has also been found that the most desirable results are achieved when the compressive force applied to the ends of the tubular steel work piece is just slightly less than the force that drive the tubular steel work piece into its yield point. A work piece previously formed by the above mentioned hydroforming operation may now be bent and subjected to a secondary hydroforming operation to produce a bent hydroformed tubular steel finished work piece having complex geometry.
