Hydroforming is a fabrication method that is regularly used in the transportation and automotive industries. Hydroforming is used so often because it allows even the most complex shapes to be created without the need to weld parts. Many automakers have relied on a traditional stamping method and a traditional welding method to fabricate components.

One of the most popular and most unconventional metal forming processes is tube hydroforming. Tube hydroforming is generally used to create various tubular components. When this process is used, tubes are shaped into different forms using internal pressure to force the blank tube to fit into the shape of the given die cavity.
For many years, American Hydroformers has worked extremely hard to become a mainstay at the front of manufacturing. American Hydroformers makes it a purpose to invest a significant amount in materials and technologies we know will offer our customers the most advantages and benefits. Since we offer a variety of forming and stamping methods, American Hydroformers can find the best methods for the products.
Deep draw hydroforming is in competition with a variety of other manufacturing processes that are used to create things we use on a daily basis. However, there are several differences when it comes to deep draw hydroforming that sets this process apart from the other manufacturing processes. Deciding the right choice can certainly be confusing, and you will likely hear different opinions and advice as you are considering the right method for your needs. Unfortunately, some of those opinions and advice will be based on myths and misconceptions.
Overview of Tube Hydroforming
Tube hydroforming is one of two groups within the broader category of hydroforming itself, along with sheet hydroforming. It is a relatively new manufacturing process, but it has led to very impressive results. The process involves expanding metal tubes into a different form through the use of a pair of die halves. The die halves support the raw tube. The cross-sectional tube structure is altered as a result of the internal pressure involved.
Tube Hydroforming, a metal fabricating and forming process, helps to shape metals into their desired shapes. This technique can be used to shape various metals including steel, aluminum, brass, copper, and stainless steel. It is a cost-effective process that uses a highly pressurized fluid in order to shape metal. It is best used to replace the older process of stamping two halves then welding them together. The process of tube hydroforming saves on labor, tools, and material costs. But how does it work?
Here on the blog, we enjoy bringing you regular posts about the benefits of hydroforming. Today we’d like to take a step back and present a lesson on hydroforming for beginners: what the process entails and why it matters.
Since the 1990s, hydroforming has been revolutionizing specific aspects of various industries. Advances in hydroforming have affected our lives more than most of us even know. The best way to prove this point is to help you imagine a world without hydroforming.
In a world without hydroforming, automobiles are heavier, weaker, less safe, more expensive, and significantly less fuel efficient.
Tube hydroforming has drawn increased attention in the automotive industry due to its advantages… Hydroformed parts can provide
The advantages of hydroforming are many. Mostly, they revolve around material efficiency, speed and cost savings. Traditional deep drawing methods suffer from the effects of drawing stress (on the materials) during the process. This is hard to avoid or minimize even when preventive measures are put into place. Fortunately, innovative techniques such as hydroforming address these points. The result is a more fine-tuned deep drawing process, which leads to better overall quality.
Hydroforming utilizes a pressurized oil chamber and a diaphragm which exerts pressure onto a punch. The little details like this matter all the more when you are dealing with intricate shapes or specialized designs. For example, a project that requires fine-tuning your psi would be ideal for hydroforming. Where wrinkling or warped materials would be a concern with traditional deep drawing, hydroforming affords you the high precision with pressure control.
One of the strongest advantages of hydroforming is that a wide variety of metals are still viable for this process. From stainless steel to aluminum, you don’t limit your choices here. Furthermore, not all metals or specific metal shaping scenarios are met well with traditional stamping techniques. It’s too broad of a solution, so again we round back to hydroforming as a more intricate, fine-tuned method. Cost savings play in here, too. With hydroforming, you cut down on costs related to development by eliminating the need for steel tooling and accommodating for various materials. Whatever the material, hydroforming can accommodate it.
Finally, Hydroforming is simply more efficient and offers a wider variety of solutions. It’s the best of all worlds for deep drawing.
The benefits of THF include:
- Seamless bonding
- Increased structural strength
- Better load support compared with stamped sheet metal
- Reduced weight
- Ability to maintain high-quality surfaces for finishing
- Fewer parts, which means lower tooling cost
- Less scrap
- Lower capital costs
- Reduced dimensional variability
- Increasing uses and applications
