Isostatic moulding apparatus comprises a fixed frame assembly comprising an upper bolster, a lower bolster and connecting rods with a clamp cylinder in the lower bolster; a pressure vessel with removable end members is mounted on a support which is pivotably mounted on one of the connecting rods so that the pressure vessel can be swung into the fixed frame assembly to overlie the piston of the clamp cylinder. The pressure vessel and the clamp cylinder are connected to a common source of hydraulic pressure fluid so that application of pressure simultaneously clamps the end members and effects moulding of a compact within the pressure vessel. After the pressure vessel is swung out of the fixed frame, a cylinder is extended to move a trolley down cam tracks to lower the bottom end member of the pressure vessel so that the compact can be removed therefrom. After the bottom end member has been raised again the top end member can be removed to allow a further charge of powder to be loaded into the pressure vessel for a further cycle of operation.
