Abstract
Provided is a system and method of making a door having first and second door skins and an internal frame. The top and bottom surfaces of the frame are coated with an adhesive and the frame is placed on a first door skin. The second door skin is then placed on the opposite surface of the frame. The assembled components are then pressed to bond the first and second door skins to the frame with a press having upper and lower dies configured to impart a larger compression force toward a central area of the door skins. Wear resistant belts or membranes are provided to protect the door skins from being marred by the upper and lower dies during the pressing process.
