Explosive forming converts electrical energy stored in a capacitor bank into hydraulic pressure.
Utilizing explosive forming, parts can be formed from either a tube or a flat sheet.
(The illustrations above give an example of the method in which both are formed.)
After the blanks are loaded into a form die, the chamber is filled with water and
a pair of electrodes is inserted into the work chamber.
The capacitor bank is then discharged through the electrodes and an interconnecting
initiating filament. This produces an expanding plasma channel and a high intensity
shock wave which combine to force the workpiece to move outward against the die.
