<p>A method of casting polymethyl methacrylate in panels (1) with an incorporated decorative design or pattern comprises the steps of positioning a removable die (2) on a first plate of glass (3), which establishes the contours (9) of the pattern, adding a sheet of ultraflexible imprinted film (4) capable of adapting closely to the contours of the die (2), and placing inserts (5) of contrasting material on the surface of the film in positions afforded by matching recesses (10) created within the contours (9); seals (7) are then positioned around the periphery, a second plate of glass (6) is offered and secured with clips (8), whereupon methacrylic resin is poured into the void between the plates (3, 6) and polymerized. On separation of the plates, the polymethyl methacrylate panel (1) emerges with the inserts (5) fully embedded and the surface bearing the impression of the imprinted film (4). <IMAGE></p> |
