A process for producing a curved vehicle screen, comprises pressing a plastic film (22) onto a curved glass sheet (18) using a flexible die (24), to form a film laminate (26). The plastic film is laminated onto the glass at reduced pressure and increased temperature. A process for producing a curved vehicle screen, comprises pressing a plastic film (22) onto a curved glass sheet (18) using a flexible die (24), to form a film laminate (26). The plastic film is laminated onto the glass at reduced pressure and increased temperature. The die consists of a glass or thin metal film which is less than 1mm thick. Glass dies are alkali free and chemically hardened. Metal dies are highly polished and consist of aluminium, brass or spring steel. An elastic coating (28) is applied to the die. Before the pressure is reduced, a non-adhesive layer with a surface micro-structure, especially a hard silk, is placed between the plastic film and the die. Heating takes place in a furnace or autoclave, and the reduced pressure is achieved using a vacuum unit. The plastic cover film consists of PET or PC and an adhesive layer between the cover film and the glass sheet consists of PU, PVB or EVA. |
