Abstract:
A method for molding objects comprising the steps of:placing a mold containing material to be hardened in a pressure container having an inside, an outside, an opening therein to allow items to be placed in or removed from the pressure container, and a bottom, wherein the container is hingedly connected to a frame having a bottom, a top and at least one side member for housing the pressure container, to allow the pressure container to swing out of the frame to a loading position and into the frame to a housed position; closing a lid, said lid connected to said frame and being sized and adapted for covering the pressure container opening to isolate an internal pressure inside the pressure container; inflating an expandable means inside said frame between the frame and the lid or between the frame and the bottom of the pressure container when said pressure container is in the housed position for pushing against the frame and the lid or against the frame and the bottom of the pressure container to push the lid and the opening in the pressure container together when the expandable means is expanded to seal the lid against the pressure container, wherein the lid and pressure container are pushed together by pushing the lid or the pressure container away from the frame; and inserting gas into the pressure container to thereby raise the internal pressure in the pressure container.
