Abstract
A press has a fixed lower platen, and an upper platen which is movable vertically by means of an actuator. A former corresponding to the article which is to be obtained is placed on the lower platen via a thermal insulation member, the former including channels for circulation of a heat exchange fluid. The material to be formed is placed on the former. The upper platen carries an assembly which has a resilient membrane, the periphery of which is sandwiched between a lower frame and a cover connected to a source of fluid under pressure, sealing between said membrane and the lid being ensured by the clamping pressure between these two parts which results partly from the force exerted on the moving platen and partly from the pressure of the fluid.
