With the use of hydroformed parts becoming increasingly common in the automotive and cycling worlds, many people are now more aware of the process used to shape ductile metals into pieces that are both lightweight and strong. But while awareness of the hydroforming process has been on the rise, fewer people know of the high-temperature metal gas forming process and its benefits.

For high-temperature metal gas forming, there are four basic stages. While they are similar to those of hydroforming, there are several distinct differences which set the process apart.

The Four Stages of High-temperature Metal Gas Forming

First, the blank is placed into the die and the ends are sealed. After this is done, the tube is pressurized. Then the docking rods then feed the material into the die, where the combination of internal pressure and simultaneous material feeding forms the tube.

Doesn’t seem too different from basic hydroforming, you might say. An understandable observation, but allow us to point out the main forming difference: the part formed at the superplastic temperature conforms precisely to the dimensions of the die.

The Benefits of High-temperature Metal Gas Forming

While quite similar to hydroforming in process in its steps, this technique allows for higher precision and yield. This in turn not only saves the industries that use it time and money, but it also produces a quality product that is that much more effective for the consumer.

In conclusion, although this process is less well-known, it is certainly no less important. Because of it, we have more better-quality sporting equipment, more advanced technologies in the aerospace and automotive industries, and (perhaps more importantly to some of us) better-working indoor plumbing.
