Video of the Triform deep draw and fluid cell sheet hydroforming processes from inside a press. The downward-acting diaphragm primarily holds the material in place during pressurization as the tool is extended atop a hydraulic punch cylinder. This draws the material into the bladder and allows it to flow as needed.
Through a simple deactivation of the punch cylinder, a Triform Deep Draw press can quickly transform into a Fluid Cell model. Either configuration results in significantly increased capability and capacity and a considerable decrease of the need for finishing hammers.
