Using a metal mold (8) having an insulating section provided with vapor release sections, pressure outside the metal mold (8) is reduced, and heating is performed while releasing vapor produced thereby through the vapor release sections. This can prevent insulation breakdown caused by condensation of large amounts of vapor produced by materials during molding and heating of starch-based biodegradable molded objects by means of resistance heating, dielectric heating, etc.
L'invention concerne un moule (8) comportant une partie pourvue d'orifices de vapeur située au niveau d'une partie d'isolation de celui-ci. La pression à l'extérieur de ce moule (8) est réduite et un chauffage de celui-ci est réalisé, la vapeur produite par la chaleur étant évacuée de la partie dotée d'orifices de vapeur. Ce procédé permet d'éviter une défaillance due à la condensation de grandes quantités de vapeur provenant des matières premières, au cours du moulage à chaud d'un article moulé biologiquement décomposable constitué d'amidon, par chauffage électrique ou par induction.
