摘要： An electro-hydraulic forming tool is disclosed in which a membrane is retained between two volumes of liquid that are separated by a membrane. Electrodes are provided with a high voltage impulse to create a shockwave in one of the volumes of fluid that is transferred through the membrane to the other volume of fluid. The shockwave is transmitted to a blank that is formed into a one-sided die. The blank is formed against the forming surface of the die. Air evacuation means are provided to remove air from the upper surface of one or both volumes of liquid.
