More than a decade ago, tube hydroforming grew in two directions: low-pressure hydroforming (a patented process) and high-pressure hydroforming. Since then the industry has grown to include all manner of robots, laser cutting systems, punching operations, and so on. Manufacturing consultant Gary Morphy takes us through about two decades of trends and developments and sheds some light on the future of this industry.

The growth in hydroforming use has slowed as tube hydroformers, particularly in the automotive industry, are taking a step back to examine process options in an effort to determine the most efficient, cost-effective process. Some even have reverted to stamping and welding formerly hydroformed parts. This article explains how the industry got to this point and where it's headed.

Under the right circumstances, hydroforming can be a viable, cost-effective manufacturing process. Tube hydroforming often produces stronger structural components than can be achieved with more conventional methods. This article explains tube hydroforming, describes its evolution, and discusses the factors that should be considered when deciding whether to use the process.

Tube hydroforming technology continues to develop in ways that improve part utility, economy, or process robustness. Auto parts that have recently been produced by hydroforming include roof rails, radiator enclosures, a front-end structural module, and roof rails.

Pressure-sequence hydroforming can form complex parts as well as forming most ductile metals, including high-strength, low-alloy, and stainless steels with sharper corners, thick-walled tube, and other difficult features.
