Abstract: A die apparatus including a first die element and a second die element is provided. The first die element is arranged with the second die element for disposal of a blank therebetween and includes a coolant channel and a trim groove for alignment with a trim line of the blank. A groove insert is disposed within the trim groove arranged to support a portion of the blank extending thereover and to reduce a cooling rate of the blank. The groove insert may be of a material including reflective radiation characteristics to reduce heat transfer from portions of the blank adjacent the trim line. The first die element may include a cavity aligned with a pierce region of the blank so that the pierce region does not contact an adjacent die element surface.
