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.
