Abstract:
A method of forming at least one aperture in at least one sheet of material utilizing a flex die punching apparatus, the apparatus having a first plate, a die having at least one aperture positioned adjacent to the first plate, a flexible, extrudable platen positioned adjacent to the at least one aperture of the die and adjacent to at least a portion of the remainder of the die, the flexible, extrudable platen having at least one punch feature corresponding to the shape, size and position of the at least one aperture of the die, there being but one punch feature for each aperture, and a second plate positioned adjacent to the flexible, extrudable platen, the method comprising the steps of:placing at least one sheet of material between the flexible, extrudable platen and the die; andforcing the first and second plates together, the at least one punch feature of the flexible, extrudable platen being caused by the step of forcing to move towards the first plate and through the at least one aperture of the die so as to extrude a portion of the at least one sheet of material through the at least one aperture of the die, thereby forming at least one aperture in the at least one sheet of material corresponding to the shape, size and position of the at least one aperture of the die.
