Abstract: Methods and systems for forming hinged starch-bound matrices. Starch-based compositions are molded between heated molds in order to form a cellular matrix and also to remove the water from the starch-based compositions in order to form a binding matrix of solidified starch. The molding apparatus is configured to form one or more creases within the hinge area in order to define one or more lines upon which the hinge will bend. The molding apparatus is also configured such that the region of the mold corresponding to the inner surface of the hinge area will transfer heat more slowly to the inner hinge surface, resulting in reduced thickness of the skin of the inner hinge. This increases the collapsibility, or ability of the inner surface of the hinge to fold or buckle, during the bending action. This in mm reduces the bending radius of hinge such that the hinging action exerts less strain on the outer surface of the hinge.

Abstract: An apparatus for causing the polymerized excess monomer to separate from a molded lens by increasing the surface energy of the flange area of one mold piece, causing the polymerized excess monomer to stick thereto. Specifically when manufactured under inert atmosphere conditions, a particular manifold is needed to supply an oxygen bearing gas, air, to the area to be treated while preventing the oxygen from contaminating the lens manufacturing area of the molds or diluting the nitrogen atmosphere of other lens process areas. It has been found that generation of the ionized oxygen by means of a corona treatment electrode sufficiently increases the adherence of the polymer to the mold piece so treated.
