<p>In a method for producing rigid plastic products comprising a thermoformed, fibre-reinforced backing material (10) and an outer layer of a thermoformed, flexible film or foil sheet material (6), the two materials are preheated and thereafter brought together in a compression and moulding tool (1), where they are compression moulded and given their final shape. The method is a one-step method with work cycle times of about 40-60 s. The end product is given a very high surface finish, and there is no need for any complementary work. Furthermore, no solvents are required. A device for carrying the method into effect comprises, apart from the above-mentioned compression and moulding tool (1), feeding means (5, 7) and a preheating oven (8) for the film or foil sheet (6), as well as a feeding means (11) and a preheating oven (9) for the backing (10). In the moulding and compression tool (1), vacuum moulding and compression moulding are combined in one step of operation.</p> |
