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.

You can use several strategies for starting a hydroforming operation on a limited budget. Review your alternatives for selecting a press, fluid intensification system, and developing the tooling necessary for your operation before you take the plunge.
A typical tube hydroforming system is shown in Figure 1. Within this system, a host of factors must be taken into account, from starting tube geometry and material properties to the quality of the final part (such as thickness distribution and dimensional accuracy).
Recent advances at the University of Stuttgart and acfross the industry have opened doors for hydroforming all kinds of materials and shapes.

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.
