The evolution of tube hydroforming

June 12, 2007 | By Gary Morphy

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.

Straining to understand bending?

April 10, 2007 | By Dr. Ho-Kook Lee, C.J. Van Tyne

Before you can hydroform tube, you bend it. Then it springs back. You can compensate by overbending it, but first you have to predict the amount of springback.

The evolution of tube hydroforming

October 10, 2006 | By Gary Morphy

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.

Tube hydroforming for expanded design options

June 13, 2006 | By Paul Tauzer

Hydroforming has become a favored technology for automotive parts because it allows manufacturers to increase a component's strength, reduce its weight, and reduce the number of parts in an assembly. Another important benefit, one that is often overlooked, is the increase in design freedom this technology allows. Engineers and designers must be aware of the factors that restrict design freedom, such as material characteristics and press limitations, and alternatives such as annealing and axial feeding that help work around these limitations.

Introduction to Tube Hydroforming

June 13, 2006 | By Gary Morphy

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.

A new use for hydraulic presses

May 9, 2006 | By Andreas Kinzyk

The use of high-strength steels (HSS) and ultrahigh-strength steels (UHSS) has made stamping complex structural automotive components increasingly difficult and capital-intensive. Changing from traditional stamping (at room temperature on a mechanical press) to hot stamping (at elevated temperatures on a hydraulic press, with a water-cooled die for quenching) provides a suitable alternative for OEMs that produce these challenging parts.
