The new EPA mandates on diesel emissions have forced manufacturers to repackage their systems and add additional components to already crowded vehicles. Modern day exhaust systems are perfect candidates for the Hydroforming process.
The hydroforming ability to create custom shapes allow designers to get the packaging and flow paths required. Shape changes such as round and rectangular sections are best achieved by hydroforming as typical material requirements are 400 series stainless steel, as well as the corrosion resistance required. Common operations include bending, pre-forming, Hydroforming, annealing and laser cutting/trimming.
