Abstract

A method and apparatus for moulding thermosetting plastic articles using pressurised fluid to force the thermosetting plastic to conform to the mould for curing is described. The pressure for curing the thermosetting plastic is provided by the pressurised fluid instead of a hydraulic press or ram. A mould tool (108) is described having a movable section to relieve unwanted pressure in the mould after the work piece has been cured. A process is described in which pressurised heated liquid is used to transfer heat to the plastics to cure them and in which the pressure of the liquid may be controlled by the application of pressurised gas.
