ABSTRACT:
Metal forming apparatuses provide enhanced thermal efficiency by reducing thermal conduction from a forming tool to a shield. In one embodiment, a shield extends between a tool and a mounting plate, and is in conductive heat transfer relationship with the tool via a plurality of protuberances. In another embodiment, a shield extends between a tool and a mounting plate, and thermally insulating material separates the tool and the shield.
