Abstract:
A method of forming a metal work piece into a target shape, said method comprising the steps:(a) obtaining a metal work piece, said work piece having an original shape;(b) disposing said metal work piece in a mold comprising at least one electromagnetic actuator, said mold comprising:(i) a male mold portion having a mold side and a back side;(ii) a female mold portion having a mold side and a back side;said mold side of said male mold portion and said mold side of said female mold portion adapted to mate so as to deform a work piece disposed therebetween;(iii) at least one of said mold portions comprising said at least one electromagnetic actuator; and(iv) a current power source adapted to produce a current pulse through said at least one electromagnetic actuator, so as to produce a magnetic field so as to be capable of deforming said work piece;(c) closing said mold sides upon said metal work piece while causing at least one current pulse to pass through said at least one electromagnetic actuator, so as to deform said metal work piece from said original shape to said target shape.
