Abstract

L'invention concerne un procédé pour mouler par injection ou par extrusion, un espace libre ou un vide étant ménagé entre deux corps ou deux supports à des températures différentes. Selon l'invention, une barrière constituée d'un matériau thermo-isolant (C) est installée dans l'espace libre ou le vide, ladite barrière comprenant au moins un matériau isolant qui possède un indice de conductivité thermique inférieur à celui de l'air sec à 0 C et est conçue pour limiter la dispersion thermique liée aux mouvements de convection et/ou à la conduction de chaleur de l'air et à une irradiation qui dépend des caractéristiques du corps à une température plus élevée.
