ABSTRACT:
The present invention is an apparatus for formimg a metal work piece into a target shape, the apparatus comprising: (a) a male mold portion having a mold side and a back side; (b) a female mold portion having a mold side and a back side; at least one of the mold side of male mold portion and the mold side of female mold portion comprising a removable portion and adapted to mate incompletely so as to deform a work piece disposed therebetween into a precursor shape, so as to leave at least one precursor area of the work piece to be finally formed; (c) the removable portion comprising at least one electromagnetic actuator, the removable portion disposed so as to be capable of further forming the at least one precursor area. The invention additionally may comprise: (d) a current power source adapted to produce a current pulse through the at least one electromagnetic actuator, so as to produce a magnetic field in the at least one precursor area so as to deform the at least one precursor area into a target shape.
