A heating structure includes an opening that surrounds a heating element and a heat transfer element. Each heat transfer element is disposed between an exterior surface of the heating element and an interior surface of the opening. A clamping mechanism is used to clamp each heating element against a heat transfer element. Each heat transfer element partially surrounds a heating element and is configured to create at least two elongated and spatially separate contact regions along a length of the heating element. The at least two contact regions form a line of contact between the heating element and the interior surface of the opening when the heating element is clamped against the heat transfer element. The at least two contact regions allow the heating element to transfer heat to the opening and to the tooling device. The clamping mechanism may also be used to transfer heat to the tooling device.
