Automakers face a number of challenges in providing consumers with vehicles that are safe, fuel efficient and reliable. One way they are achieving these goals is with the use of hydroformed automotive parts. Hydroforming is a metal fabrication process that uses high pressurized fluid and a specialized type of die molding that produces parts which are lightweight, cost-effective and although thinner, have increased strength and structural integrity.
BMW has been using hydroformed parts in their high performance vehicles for several years. The BMW M3 features hydroformed exhaust tubes, for instance. Ford utilized hydroformed steel tubes in the B-pillars and a hydroformed roof rail in the 2013 Ford Fusion. The structural superiority as well as the lighter weight and reduced costs are key reasons that automakers have begun to incorporate hydroformed parts into their newer models.
Weight is increasingly a concern for both consumers and automakers due to EPA regulations regarding fuel efficiency. A lighter vehicle enjoys improved MPG, in fact, according to the EPA, every 100 pounds of extra weight in a vehicle reduces the MPG by 2 percent.
But perhaps more important than weight and MPG, is safety. Hydroformed parts have a higher stiffness to weight ratio and increased strength. The absence of welding joints means these parts have a greater ability to absorb crash energy. This means vehicles have greater crash worthiness which translates into improved safety for the occupants of the vehicle in case of a crash.
For improved safety and structural strength as well as reduced weight and overall production costs, hydroforming is a perfect solution for the performance automotive industry.
