Abstract

The subject of the invention is a method of manufacturing aluminum, single-leaf, rebated, full entrance doors, consisting of a frame and a door leaf, used in particular in residential construction and industrial facilities. The method of producing aluminum doors is based on painting the raw, full-length aluminum internal and external sections of the frame and leaves (2) in the desired color and drying them. Painted aluminum internal sections and aluminum external sections of the frame and sashes (2) are connected with thermal strips (3), by crimping them, creating frame profiles and door leaf profiles (2). Then put the door rebate gaskets (4) in the leaf profiles (2). The full-length frame and leaf profiles (2) prepared in this way are cut to the required dimensions. In the cut profiles of the frame and leaf (2), mill and drill technological holes (5). Then, at the assembly station, in the milled profiles of the frame and sash (2), we install the fittings (6) in the prepared technological holes (5). Then the frame profiles with fittings (6) are folded into frames, and the leaf profiles (2) with fittings (6) are folded into frames (7b) by mounting aluminum fittings (8a), sheet metal fittings (8b) in their corners, and then glue the seals (9). Then, on the gluing and pressing station, while the glue is open, we arrange and position the individual elements of the aluminum door one by one, starting with the inner cover plate, the leaf frame (7b), the filling (11) and the outer cover plate, precisely applying two-component adhesive layers between them in the appropriate places, then move the whole thing to the drawer. We repeat this process three times. Then we iron three doors simultaneously. After cooling down and bonding of the adhesive layer, the three stretched wings and the matching frame frames are transferred to the inspection and packing station.
