<p>A method for the manufacture of box elements composed of two shells (7, 8) of thermosetting and/or thermoplastic polymeric material glued together, in which the operations for the moulding and gluing together of the two shells (7, 8) are integrated. This integration is possible by virtue of the use, with a vertical press (1), of a three-plate die (2, 3) with a removable punch (4), in which the two shells (7, 8) are moulded simultaneously and then glued together.</p> |
