Verfahren und Vorrichtung zum Herstellen von dünnwandigen laminierten Formteilen |
摘要 |
A process is disclosed for manufacturing thin-walled mouldings with a ground layer (4) made of thermoplastic materials and a covering layer (5) made of prefabricated flat covering materials pressed together with the ground layer by a back pressing technique in a form tool (8) having a top die (6) and a bottom die (7). The object of the invention is to produce thin-walled mouldings having laminated and non-laminated areas in a simple manner, with no danger of damaging sensitive covering layer materials and with non-laminated areas having a high quality surface. For that purpose, during or after back pressure lamination, i.e. while or after the two dies are closed, besides at least one moulding area (2) laminated with a covering layer by a back pressing technique, at least another area (3) of the moulding is produced by a conventional injection moulding technique, i.e. by injecting molten thermoplastic materials in the part of the moulding cavity (17) in which the area of the moulding which is not laminated with a covering layyer (5) is produced. A moulding in a single piece is thus obtained.
