Abstract:
1. A heating and forming apparatus for sheet material, said apparatus comprising: first and second respectively movable forming dies; said first forming die having a forming surface and at least partially defining a cavity with said second forming die, said cavity being adapted to receive a sheet material therein; a heating mechanism within said cavity for heating said sheet material; a pressurization mechanism in communication with said cavity, for applying pressure to move said sheet material into conformity with said forming surface of said first forming die; an induction coil assembly energizable within said cavity and positioned proximate to said sheet material for selectively inductively heating said sheet material; and wherein said inductive heating of said sheet material assists said pressurization mechanism in forming said sheet material into conformity with said forming surface, through generation of electromagnetic force.
