The evolution of tube hydroformingMore 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 evolution of tube hydroformingThe 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.

Introduction to Tube HydroformingUnder 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 Design Flexibility—Part IX:In this last article in a nine-part series, Gary Morphy reviews high-pressure and pressure sequence hydroforming and discusses factors to consider when deciding which process is best for a particular application. The decision should be based in part on anticipating future needs.

Tube Hydroforming Design Flexibility—Part VIII: Dimensional StabilityWhether they are producing automobiles or hydroforming press parts, designers, manufacturers, and assembly personnel are very concerned about dimensional stability. Surfaces and holes must be located in a specified range and smaller is better. Concern escalates as the drive to improve quality and reduce build tolerances and problems increases.

Part feature developments in hydroforming productsTube 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 and high-pressure hydroforming: Knowing the processes can mean boosting profitsPressure-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.
