Hydraulic bulge test in hydroforming. As with all operations creating shapes and parts out of metal, the stress and strain must be tested to ensure safety. If a company is creating car roofs using hydroforming out of sheets of metal, hydraulic bulge testing can help determine if the car roof can take the required stress and strain of driving and even accidents.

Tube hydroforming is accomplished in one of two ways, either high pressure or low pressure. The desired shape and strength of the metal tube determine the level of pressure that will be used.
From time to time, new discoveries change the way we approach various aspects of industry and technology. Recently, the discovery of a new metal has us doing exactly that.
Over the course of many years, there have been numerous misconceptions about deep draw metal stamping and how the deep draw process works. For those who are unfamiliar with the deep draw metal stamping process, this is a manufacturing process that remains in competition with others in order to create a product that has a few similarities or one that is completely the same. However, the deep draw metal stamping process has a few major differences that separate it from the other methods and processes.
The welding technique, friction stir welding, was developed almost 30 years ago in 1991. Although it was invented many years ago, it has seen a high rise in demand over the past few years. One of the main reasons that friction stir welding has seen such a massive increase is due to the rising demand for greater strength and durability in applications.
Lauded as the most significant innovation in metal joining in the last decade, Friction Stir Welding (FSW) introduces a solid-state joining process that is environmentally friendly, versatile, and energy efficient. FSW outperforms conventional fusion welding by joining aerospace aluminum alloys, and other metallic alloys, that are high-strength. The significance of this advancement is that aerospace aluminum alloys, like 2XXX and 7XXX series, have been classified as virtually non-weldable with conventional welding processes because of porosity and microstructure solidification behavior. Resistance welding can be performed on aluminum alloys, however, surface preparation has to be performed, which is expensive and surface oxide becomes a problem.
Here at American Hydroformers, we pride ourselves in keeping current with industry trends. That is just one of the many reasons why people to trust us with their high-temperature metal gas forming needs.
Although your average American probably has not heard of high metal gas forming, that does not mean they have not taken advantage of products made possible (or made better) through it. Those of us in the industry know better. We recognize that the vast majority of us would lead less comfortable and convenient lives without high-temperature metal gas forming.
Although the process of high-temperature metal gas forming may not be common knowledge, most people benefit from this process on a daily basis. They just don’t know that they do.
In 2015, Ford’s F-150 was the first high-volume vehicle produced with an aluminum frame, reducing the F-150’s weight by 700 pounds. Since then, the need for strong, lightweight material is driving a significant increase in the use of hydroformed aluminum to make automobiles that are both fuel and cost efficient while retaining key safety features.
