Hydroforming Y-shaped stainless steel exhaust components

November 29, 2001

By:

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.
