Abstract

A method is provided of making a door facing blank that includes a central portion, first and second side portions adjacent to and integral with opposite sides of the central portion, opposite interior and exterior surfaces, and a design element including a molded portion and an embossed portion. The side portions include stile-receiving areas that are substantially planar. The molded portion is molded in the central portion to establish a first groove in the exterior surface of the central portion and a protrusion on the interior surface of the central portion. The embossed portion is embossed in the first side portion to establish a second groove in the exterior surface of the first side portion but no protrusion on the interior surface of the first side portion. The first and second grooves are continuous.

First claim

We claim:

1. A method of making a door, comprising the steps of:
pressing a substrate in a mold press comprising an upper die mold and a lower die mold that collectively form a cavity for molding and embossing the substrate into a door facing blank having a central portion, first and second side portions adjacent to and integral with opposite sides of the central portion, an exterior surface, an interior surface, and a design element, the upper die mold comprising a protruding molding die feature and a first protruding embossing die feature, the lower die mold comprising a depression molding die feature aligned with and complementary to the protruding molding die feature of the upper die mold and a first substantially planar die feature aligned with the first protruding embossing die feature of the upper die mold,
wherein said pressing of the substrate in the mold press causes the protruding molding die feature of the upper die mold and the depression molding die feature of the lower die mold to form a molded portion of the design element in the central portion but not the side portions of the door facing blank, the molded portion of the design element comprising a first groove in the exterior surface of the central portion and a corresponding first protrusion on the interior surface of the central portion, the first protrusion being aligned with and complementary to the first groove,
wherein said pressing of the substrate in the mold press causes the first protruding embossing die feature of the upper die mold and the first substantially planar die feature of the lower die mold to form a first embossed portion of the design element in the first side portion, the first embossed portion of the design element comprising a second groove in the exterior surface of the first side but no corresponding second protrusion on the interior surface of the first side portion so that the interior surface of the first and second side portions form substantially planar first and second stile-receiving areas that are longitudinally extending and spaced from one another,
wherein the first and second grooves are continuous with one another, and
wherein the method further comprises
forming an additional door facing blank according to said pressing step;
trimming the door facing blank and the additional door facing blank adjacent to the first and second stile-receiving areas to provide the door facing blank and the additional door facing blank with selected widths; and
securing the first and second stile-receiving areas of the door facing blank and the additional door facing blank to opposite sides of first and second spaced stiles of a door frame to make a door.

2. The method of claim 1 , wherein the first and second stile-receiving areas are trimmable to reduce an overall width of the door facing blanks.

3. The method of claim 1 , wherein the molded portion of the design element has a depth of at least about 0.07 inch.

4. The method of claim 1 , wherein the molded portion of the design element has a depth that is greater than a thickness of the door facing blank.

5. The method of claim 1 , wherein the door facing blank comprises a member selected from the group consisting of cellulosic composite, polymer composite, and metal.

6. The method of claim 1 , wherein:
the upper die mold further comprises a second protruding embossing die feature, and the lower die mold further comprises a second substantially planar die feature aligned with the second protruding embossing die feature of the upper die mold,
wherein said pressing of the substrate in the mold press causes the second protruding embossing die feature of the upper die mold and the second substantially planar die feature of the lower die mold to form a second embossed portion of the design element in the second side portion, the second embossed portion of the design element comprising a third groove in the exterior surface but no corresponding third protrusion on the interior surface, and
wherein the first and third grooves are continuous with one another.

7. The method of claim 1 , wherein the first and second grooves collectively define a continuous central bead.

8. The method of claim 1 , wherein the first and second grooves collectively establish one of a plurality of linear grooves extending parallel to one another to simulate an appearance of a plurality of planks in the exterior surface.

9. The method of claim 1 , wherein the design element comprises simulated first and second planks separated from one another by the first and second grooves.

10. The method of claim 9 , wherein the first and second planks are slanted relative to top and bottom edges of the door facing blank.

11. The method of claim 1 , wherein the design element comprises a simulated organic element.

12. The method of claim 11 , wherein the simulated organic element comprises a member selected from the group consisting of a plant and a flower.

13. The method of claim 1 , wherein the design element comprises a geometric shape.

14. The method of claim 13 , wherein the geometric shape is a square.

15. The method of claim 13 , wherein the geometric shape is a circle.

16. A method of making a door, comprising the steps of:
pressing a substrate in a mold press comprising an upper die mold and a lower die mold that collectively form a cavity for molding and embossing the substrate into a door facing blank having a central portion, a frame portion surrounding and integral with the central portion, an exterior surface, an interior surface, and a design element, the upper die mold comprising a protruding molding die feature and a first protruding embossing die feature, the lower die mold comprising a depression molding die feature aligned with and complementary to the protruding molding die feature of the upper die mold and a first substantially planar die feature aligned with the first protruding embossing die feature of the upper die mold,
wherein said pressing of the substrate in the mold press causes the protruding molding die feature of the upper die mold and the depression molding die feature of the lower die mold to form a molded portion of the design element in the central portion but not the frame portion of the door facing blank, the molded portion of the design element comprising a first groove in the exterior surface of the central portion and a corresponding first protrusion on the interior surface of the central portion, the first protrusion being aligned with and complementary to the first groove,
wherein said pressing of the substrate in the mold press causes the first protruding embossing die feature of the upper die mold and the first substantially planar die feature of the lower die mold to form a first embossed portion of the design element in the frame portion, the first embossed portion of the design element comprising a second groove in the exterior surface but no corresponding second protrusion on the interior surface so that the interior surface of the frame portion forms substantially planar first and second stile-receiving areas that are longitudinally extending and spaced from one another at opposite sides of the frame portion and substantially planar first and second rail-receiving areas at opposite ends of the frame portion,
wherein the first and second grooves are continuous with one another, and
wherein the method further comprises
forming an additional door facing blank according to said pressing step;
trimming the door facing blank and the additional door facing blank adjacent to the first and second stile-receiving areas to provide the door facing blank and
