Claim 5:
6. The claim 1, further comprising a controller comprising a processor and a memory storing computer-readable instructions which, when executed by the processor, perform processes, including:
pre-heating the press plates by flowing a hot fluid through the fluid circulation loop;
closing the press by moving the pre-heated press plates towards one another and exerting a pressure on a starting structure of the sandwich panel to be manufactured;
continuing heating the press plates by flowing a hot fluid through the fluid circulation loop thereby heating the starting structure to the foaming temperature, while exerting a pressure on the starting structure;
foaming the starting structure at the foaming temperature by moving the press plates a predetermined distance apart, while maintaining a pressure on the structure being foamed;
interrupting the flow of hot fluid through the fluid circulation loop;
cooling the press plates by actuating the controlled expansion valve thereby converting hot pressurized water into steam; and
cooling the press plates by flowing water having a controlled temperature through the internal flow channels of the press plates.
