MOLDING METHOD OF EMBLEM OR THE LIKE BY MEANS OF THERMOPLASTIC SYNTHETIC RESIN FILM

摘要

A method for forming a gold-laced emblem of thermoplastic synthetic resin film. A woven fabric-like fine uneven pattern is formed on an outer surface of the thermoplastic synthetic resin film having a metal deposited layer on a lower surface thereof. Instead, a woven fabric-like fine uneven pattern is formed on an outer surface of metal-interposed multi-layer thermoplastic synthetic resin film. The film is superposed on an upper surface of a base, and pressed by an engraving die. The engraving die has one or more fusion cutters having sharp cutting edges along a profile line of a pattern to be shaped, and one or more pressing cutters, an edge face of which is slightly above a cutting edge face of the sharp cutting edges. The film is high-frequency-induction-heated by the engraving die. The film is plasticized and the film of a quantity corresponding to portions intruded by the cutters is swelled to both sides of the cutters. The thermoplastic synthetic resin film pattern contacted with the pressing cutter edges of the pressing cutters is melted by the pressing cutters and reduced in thickness so that the base can be visually observed through the film. The thermoplastic synthetic resin film outside the profile line is removed.
