Eliminating final trim shearing of hydroformed tube

The most common way to establish tube length after hydroforming is by cutting or shearing the tube to a specified dimension; however, cutting out this step can reduce scrap. A new method designed to eliminate this step combines forming the end of a tube to resemble its final form with using a hydroform die to correct end position variations off the bender. While this approach eliminates the final shear trim operation, it also presents new challenges.
