Abstract

This disclosure describes methods for making insulated door panels using separate façade members, in order to separate the manufacturing process of the exterior cosmetic design surface from the structural components of the door panels. This allows a same manufacturing line for the door panels to accept façade members of different designs and to produce door panels of these different designs. The facade members are made in separate production lines using various techniques, including casting, molding, vacuum forming, extrusion, and the like. The façade members are then fed into door panel production lines that fill polyurethane foams to form complete panels. The façade members become the exterior skins of the panels with minimum overlay with any backing structure to reduce material wastes, as well as lowering tooling costs for different designs due to the common backing structure that may be shared.
