1. A door press, comprising:
- an upper die having an upper surface, wherein the upper surface contains a first membrane fixed thereto, the first membrane comprising a first center portion having an upper chamber formed therein and a first peripheral portion attached to the upper surface, the upper chamber spaces the first center portion from the upper surface and is configured to accept gas to inflate the first center portion to a raised position relative to the first peripheral portion, but not to inflate the first peripheral portion; and
a lower die having a lower surface, wherein the lower surface contains a second membrane fixed thereto, the second membrane comprising a second center portion having a lower chamber formed therein and a second peripheral portion attached to the lower surface, the lower chamber spaces the second center portion from the lower surface and is configured to accept gas to inflate the second center portion to a raised position relative to the second peripheral portion, but not to inflate the second peripheral portion,wherein the center and peripheral portions of the first membrane and the center and peripheral portions of the second membranes face each other and define a mold cavity in which a door assembly is receivable therein for pressing by the center and peripheral portions of the first membrane and the second membranes.

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.
