Abstract: An electrohydraulic container forming device wherein a thin stream of conductive fluid constitutes a bridge between one electrode and the other of the shock producing electrodes. The conductive liquid is pressurized to a higher value than the internal pressure of the container. In operation the conductive liquid is emitted under pressure from one electrode by a timing circuit driving a shear type solenoid valve. A second timing circuit synchronizes the electrical discharge with the establishment of a preferentially conductive bridge across the electrode gap. A sharp jet pulse is given off from the arc thus established and this develops pressure inside the rubber diaphragm to press it against the container which is then pressed into the interstices of the die to give a fully stylized container.

THE CONDUCTIVE LIQUID IS PRESSURIZED TO A HIGHER VALUE THAN THE INTERNAL PRESSURE OF THE CONTAINER.

A SECOND TIMING CIRCUIT SYNCHRONIZES THE ELECTRICAL DISCHARGE WITH THE ESTABLISHMENT OF A PREFERENTIALLY CONDUCTIVE BRIDGE ACROSS THE ELECTRODE GAP. A SHARP JET PULSE IS GIVEN OFF FROM THE ARC THUS ESTABLISHED AND THIS DEVELOPS PRESSURE INSIDE THE RUBBER DIAPHRAGM TO PRESS IT AGAINST THE CONTAINER WHICH IS THEN PRESSED INTO THE INTERSTICES OF THE DIE TO GIVE A FULLY STYLIZED CONTAINER.
