T-shapes and Y-shapes are the most commonly hydroformed exhaust system components for automobiles. This article reports on the investigation into the metal flow in Y-shape hydroforming by the Engineering Research Center for Net Shape Manufacturing (ERC/NSM) at The Ohio State University, which conducted several experiments using the tooling available at the SPS research center in Aalen, Germany.

Many factors come into play when attempting to execute a production hydroforming operation, among them material selection, friction and lubricants, tube bending and preforming, and equipment. Many companies in the automotive sector are experiencing great success with the process, which can reduce weight, overall costs, and the number of parts per vehicle.
