ABSTRACT:
A process of making a hinged access hatch for use in marine and RV industries includes selecting a stainless hinge having a pair of leaves and rotating on a pentel or pivot pin and placing a portion of one leaf of the selected hinge into an access hatch door mold and sealing around said one leaf extending into said access door hatch mold to prevent plastic in said mold from contacting the moving portion of said hinge. The access hatch door is then molded in the access hatch mold having a portion of the one leaf of the hinge molded therein. The molded access hatch door has been removably attached to an access hatch frame by attaching fasteners through the plurality of openings in the other hinge leaf whereby an access hatch eliminates the need for hinge door fasteners while improving the strength of the access hatch door attachment to the access hatch frame.
