Title: Prodn. of flat plastic articles - by drawing decorative film across mould, cutting off outer rim, and injecting hot polymer shot to bond to and press film against tool face
IPC: B29C45/14
Filed: 1991-01-10
Abstract: Flat plastic articles, such as trays, are produced consisting of a material and a plastic film on at least the visible side. The articles are prdouced by ; (a) placing a hot stamping thermoplastic film in a thermoforming and injection moulding tool and across the area of the side to be visually apparent; (b) the film is gripped along its edges; and (c) heated polymer is applied under pressure and the film plus polymer is pressed against a surface in the thermoforming tool, this surface being that for the finally visible face, (d) the injected resin fills the space on the other side of the film and bonds to that film. Before, during or after introducing the injected resin the film is cut/trimmed/torn off round the rim of the injection mould and the offcut removed. When the thermoforming and injection moulding tool has cooled it is opened and the moulding bonded to the film is demoulded. ADVANTAGE - The method produces a prod. having good appearance. It is cheaper than similar existing processes. (0/1)
