ABSTRACT:
A multi-piece hydroforming tool is provided having a tooling die and a hydraulic pressure source. The tooling die includes a plurality of tooling cavities. Each tooling cavity includes a injector manifold in fluid communication with the hydraulic pressure source. The injector manifolds supply pressurized hydraulic fluid to each of the plurality of tooling cavities independently. Thus, multiple pieces may be formed simultaneously and independently, thereby minimizing the need to discard all the hydroformed pieces if one piece become defective.
