System for assembly of recessed panel doors

A system for making a door assembly of the kind having an internal frame, a core, and first and second door skins attached to the frame on either side of the core, wherein each of the door skins has a planar portion bordering at least one recessed panel portion, said system comprising:

• a press including an upper platen and a lower platen, wherein at least one of the upper platen and lower platen is movable from an open position of the press toward the other to a closed position of the press for pressing the door assembly in a pressing operation;
• a lower die section seated on the lower platen, the lower die section including a lower base supported on the lower platen and a raised section which stands off from the lower base, wherein the raised section has a height above the lower base greater than the depth of the recessed panel portion of the first door skin relative to the planar portion thereof, the lower base having a first outer periphery;
• and
• an upper die section that is removably attached to the upper platen and including an upper base supported by the upper platen and a raised section that stands off from the upper base, the upper base having a second outer periphery;
• a workpiece transport and positioning subsystem for transporting door components into the press, the lower platen including a plurality of channels, and the workpiece transport and positioning subsystem including a roller conveyor accommodated within the plurality of channels;
• the press, in the open position, configured to receive a stack of door components between the upper platen and lower platen, the stack including the first door skin with the recessed panel portion of the first door skin facing downward and contacting the raised section of the lower die section, the stack including the frame positioned over the first door skin, the frame defining a cavity, the stack including a compressible core overlying the first door skin and within the cavity, the stack including the second door skin overlying the compressible core and the frame and with the recessed panel portion of the second door skin facing upward toward the raised section of the upper die section;
• the press, in the closed position, configured to contact the raised section of the upper die section to the recessed panel portion of the second door skin;
• the press, in the closed position, configured to press the stack of door components between the lower and upper platens with the recessed panel portions of the first and second door skins supported by the raised sections of the lower and upper die sections, respectively, so that the recessed panel portions compress and deform a portion of the compressible core of the door assembly underlying the recessed panel portions, to thereby form the door assembly;
• the raised section of the upper die section and the raised section of the lower die section, with the press in the closed position, configured to positively contact the first door skin with one side of the frame and to positively contact the second door skin with an opposite side of the frame;
• and
• the first outer periphery and the second outer periphery, with the press in the closed position, being spaced apart to simultaneously support compressive contact of the first door skin with the one side of the frame and compressive contact of the second door skin with the opposite side of the frame, to thereby form the door assembly.
