ABSTRACT:
A quantity of material (10), which is at less than a predetermined density, is disposed within a sealed container (12) which is, in turn, disposed in a first thermal jacket (32) to retain the heat within the material (10) to be consolidated. The first thermal jacket (32) is placed within a second thermal jacket (34) which is, in turn, disposed in a cavity defined by two elastomeric components (22, 24) retained between a ram (16) and pot die (14) of a press whereby upon closure of the press, the ram (16) enters the cavity (26) of the pot die (14) to apply external pressure to the entire exterior of the elastomeric components (22, 24). A seal (36) of material harder than the elastomeric material (22, 24) is disposed within the cavity (26) of the pot die (14) for preventing the elastomeric medium (22, 24) from leaking between the sliding surfaces of the ram (16) and the pot die (14).
