What is Tube Hydroforming?

Often, when it comes to discussing what we do, the very first question asked is: What is tube hydroforming? The simplest answer is that hydroforming is a way to shape metal. This cost-effective process is used on metals such as aluminum, steel, stainless steel, copper and brass.

Hydroforming is a common application in the automotive industry, where it can produce stronger structures for vehicles such as engine cradles, suspension and radiator supports. Other examples of items that can be produced by hydroforming include kitchen spouts — which were the original intention of sheet hydroforming — as well as satellite antennas, saxaphone tubes and bicycle frames.

Before the process of hydroforming was developed, items were made by forming two halves and then welding them together. By using die molding and highly pressurized fluid to form metal, hydroforming eliminates the inefficiency of welded pieces and allows for more complex shapes and contours of the metal.

There are two types of hydroforming: sheet hydroforming and tube hydroforming. Sheet hydroforming uses one die and a sheet of metal, while tube hydroforming involves the expansion of metal tubes into a shape using two die halves which contain the raw metal tube.

Specializing in tube hydroforming, American Hydroformers has a high pressure hydroforming press system that provides higher efficiency and versatility with parts that have complex geometries or extensive secondary operations. We work with a number of industries, including automotive, appliance, diesel exhaust and plumbing. We also offer complete assembly level fabrication of automotive structures, industrial laser cutting and stencil work. For more information on our services, contact us.
