A method of manufacturing a hollow core door is disclosed, as well as a corresponding hollow core door. The method includes the steps of providing a solid flat door skin, moisturizing the flat skin, applying a conditioning resin thereto, pre-heating the flat door skin, and thereafter pressing the flat door skin between a pair of heated platens in a press in order to reform the flat skin into a molded skin including a plurality of panels defined therein. The press continuously closes in order to reform the flat skin into the molded skin, with the rate of press closure being a function of the determined hardness of the flat skin to be reformed. The resulting door skins have an improved bond strength, and are efficiently manufactured.

1. A hollow core door comprising: a door frame having opposite first and second sides;a first door skin attached to said first side of said door frame, said first door skin comprising a first planar portion, a second planar portion, and an angled offset portion between said first and second planar portions,a second door skin attached to said second side of said door frame to establish a hollow core area between said first and second door skins, said second door skin comprising an additional first planar portion, an additional second planar portion, and an additional angled offset portion between said additional first and second planar portions,wherein a thickness of said angled offset portion is less than a thickness of said first and second planar portions, and wherein a thickness of said additional angled offset portion is less than a thickness of said additional first and second planar portions; and wherein said first door skin and said second door skin are each formed of wood composite bound together with thermosetting resin. 2. The door of claim 1, wherein the thickness of said first and second planar portions is about 4 mm and the thickness of said angled offset portion is about 3 mm. 3. The door of claim 1, wherein the thickness of said additional first and second planar portions is about 4 mm and the thickness of said additional angled offset portion is about 3 mm. 4. The door of claim 1, wherein said first and second door skins each have a density of from about 550 kg/m3 to about 1200 kg/m3. 5. The door of claim 1, wherein said first and second door skins each have a density of from about 800 kg/m3 to about 1200 kg/m3. 6. The door of claim 1, wherein said first and second door skins each have a bond strength of at least 2.0 N/mm2. 7. The door of claim 1, further comprising first and second sealers applied to exterior surfaces of said first and second door skins, respectively. 8. The door of claim 1, further comprising first and second moisture impervious barriers applied to exterior surfaces of said first and second door skins, respectively. 9. The door of claim 1, further comprising a foam filling the hollow core area. 10. The door of claim 1, wherein said angled offset portion and said additional angled offset portion are contoured. 11. The door of claim 1, wherein said wood composite bound together with thermosetting resin comprises a medium density fiberboard or hard board. 12. A hollow core door comprising: a door frame having opposite first and second sides;a first door skin attached to said first side of said door frame, said first door skin comprising a first planar portion, a second planar portion, and an angled offset portion between said first and second planar portions, said angled offset portion forming a rectangle with respect to an elevational view of said first door skin to define a panel;a second door skin attached to said second side of said door frame to establish a hollow core area between said first and second door skins, said second door skin comprising an additional first planar portion, an additional second planar portion, and an additional angled offset portion between said additional first and second planar portions, said additional angled offset portion forming a rectangle with respect to an elevational view of said second door skin to define an additional panel;wherein a thickness of said angled offset portion is less than a thickness of said first and second planar portions, and wherein a thickness of said additional angled offset portion is less than a thickness of said additional first and second planar portions; and wherein said first door skin and said second door skin are each formed of wood composite bound together with thermosetting resin. 13. The door of claim 12, wherein said first and second door skins each have a density of from about 550 kg/m3 to about 1200 kg/m3. 14. The door of claim 12, wherein said first and second door skins each have a density of from about 800 kg/m3 to about 1200 kg/m3. 15. The door of claim 12, wherein said first and second door skins each have a bond strength of at least 2.0 N/mm2. 16. The door of claim 12, further comprising first and second sealers applied to exterior surfaces of said first and second door skins, respectively. 17. The door of claim 12, further comprising first and second moisture impervious barriers applied to exterior surfaces of said first and second door skins, respectively. 18. A hollow core door comprising: a door frame having opposite first and second sides;a first door skin having a first surface and further having an opposite second surface that is attached to said first side of said door frame, said first door skin formed of a first wood composite bound together with a first thermosetting resin, and comprising a first planar portion, a second planar portion, and an angled offset portion between said first and second planar portions, said angled offset portion forming a rectangle with respect to an elevational view of said first door skin to define a panel;a second door skin having an additional first surface and further having an opposite additional second surface that is attached to said second side of said door frame to establish a hollow core area between said first and second door skins, said second door skin formed of a second wood composite bound together with a second thermosetting resin, and comprising an additional first planar portion, an additional second planar portion, and an additional angled offset portion between said additional first and second planar portions, said additional angled offset portion forming a rectangle with respect to an elevational view of said second door skin to define an additional panel;wherein a thickness between said first and second surfaces of said angled offset portion is less than a thickness between said first and second surfaces of said first and second planar portions, and wherein a thickness between said additional first surface and said additional second surface of said additional angled offset portion is less than a thickness between said additional first surface and said additional second surface of said additional first and second planar portions. 19. The door of claim 18, wherein said first and second door skins each have a density of from about 550 kg/m3 to about 1200 kg/m3. 20. The door of claim 18, wherein said first and second door skins each have a density of from about 800 kg/m3 to about 1200 kg/m3. 21.
