  • Patent number: 10889031
    Abstract: The present invention is related to a method and an apparatus for curing a polymeric form. The method includes arranging an uncured polymeric form within a curing chamber (60) formed by a base member (20) and a constraining member (40). A thermal expansion member (30) is additionally positioned within the curing chamber (60) with the uncured polymeric form (70) such that the thermal expansion member and the uncured polymeric form are positioned between the base member (20) and the constraining member (40). The thermal expansion member (30) is heated to expand in size into an expanded state. In the expanded state the thermal expansion member (30) applies pressure to the uncured polymeric form (70) within the curing chamber. The expansion of the thermal expansion member (30) is maintained to maintain the application of pressure to the uncured polymeric form while the uncured polymeric form is being cured to form a cured polymeric form.
