Abstract
A first layer is established on a second layer and an induction coil is disposed within induction proximity to the second layer. The induction coil is electrically energized thereby heating the second layer to a target temperature. A die having a die cavity is translated from a first location spaced substantially beyond an induction heating distance from the induction coil to a clamping location adjacent the second layer such that the induction coil surrounds a predetermined location on an external surface of the die. The die is heated by induction between the induction coil and the die while the die is translated toward the clamping location until the die reaches a predetermined die temperature. The induction coil is de-energized after the die has reached the predetermined die temperature. The first layer and the second layer are clamped between a binder and the die.
