Abstract

The present invention relates to a wood composite panel having a major planar portion, at least one panel portion, and an inwardly extending contoured portion surrounding the panel portion and interconnecting the major planar portion and the panel portion. The contoured portion defines an inter-relationship between a vector angle and a deep draw depth that achieve a satisfactory stretch factor. The present invention also relates to a door having the disclosed wood composite door facings, and methods of forming the facing and door.

Claims (9)

1. A method of forming a wood composite door facing, comprising the steps of:

providing a mold having a lower die and an upper die, wherein the lower die has a flat portion and at least one die cavity, and the upper die has a flat portion and at least one downwardly extending contoured design complementary to the at least one die cavity;

disposing a cellulosic mat between the lower and upper dies; and

compressing the cellulosic mat between the lower and upper dies to form a door facing having a contoured portion and a planar portion, the contoured portion extending inwardly from and relative to a first surface of the planar portion adapted to be exteriorly disposed and opposite to a second surface adapted to be interiorly disposed, wherein the contoured portion has a vector angle and a draw depth that achieve a satisfactory stretch factor as shown in FIG. 6 .

2. A method of forming a door, comprising the steps of:

providing a peripheral frame having first and second sides;

securing a first door facing to the first side of the frame, the first facing having a contoured portion and a planar portion, the contoured portion having a vector angle and a draw depth that achieve a satisfactory stretch factor as shown in FIG. 6 ; and

securing a second door facing to the second side of the frame, the second facing having a contoured portion and a planar portion, the contoured portion having a vector angle and a draw depth that achieve a satisfactory stretch factor as shown in FIG. 6 , the contoured portion of the second facing being aligned with and abutting the contoured portion of the first facing.

3. The method of claim 2 , including the further step of adhering a core to an interiorly disposed surface of the first door facing prior to securing the second door facing.
