Optimized crash characteristics: hydroformed parts for chassis and body
Description
Parts manufactured by the hydroforming method are notable for their improved crash characteristics. They are lighter, but, at the same time, more rigid and stronger. These are advantages that convince manufacturers to use hydroforming for more and more chassis and body parts. Chassis parts, for example, are manufactured for off-road/SUV vehicles and light trucks. In the case of the auto body the hydroforming manufacturing method is used primarily for frame applications. In the USA alone, for example, the market for hydroformed [frame] parts has grown by several million parts per year. The benefits of hydroforming as compared to conventional methods are also seen, for example, in the manufacture of A, B, C, and D-pillars, roof frames, and transverse rails.View
