Abstract

The invention is directed to a molding apparatus, including a cylinder having an interior sidewall and a fluid inlet, and defining an inner cavity. A porous plate is disposed within the inner cavity, and is disposable in a loading position wherein the inner cavity is divided into a fluid flow chamber and a material chamber. A
ram having an outside diameter which is less than the diameter of the cylinder interior sidewall is slidable within the cylinder.
