A high impact resistant rotationally molded door and process for molding the door has the hinge post integrally attached to the rotationally molded skin of the door. A hinge member is provided that has a perforate U-shaped metal sheet bonded to preferably the upper portion of the hinge post. The sides of the U-shaped metal sheet are spaced sufficiently apart so that registration with the subsequently rotationally molded plastic skin of the door occurs. This hinge member at the perforate metal sheet rapidly heats during rotational molding. The perforate m...


1. A process of molding a high impact resistant door comprising the steps of:providing a mold having an interior for defining a hollow rotationally molded six sided door including; a front door surface; a rear door surface; a top door edge; a bottom door edge; a hinge door edge; and, an opening door edge; said surfaces and edges of said provided mold forming an integral hollow cavity in the interior of said door, providing an elongate hinge member for placement into said mold; providing a U-shaped perforate metal member having opposite side edges of the ...
