Abstract:
1. A manufacturing method of a film insert molded article, comprising steps of: printing on a film to form a printing ink layer; printing a binder layer on the printing ink layer to form a binder layer; performing a die-cut on the film by cutting the film after adding an outer circumferential bending amount (a) to the film to be subjected to the die-cut in a manner that an outer circumferential side surface of a product is enwrapped with the film; performing a forming process in which circumferential bending and 3-dimensional shaping are performed via press-molding after pre-heating the film subjected to the die-cut; and injecting molten resin into an injection molding die after the film subjected to the forming process is set on a cavity surface of the injection molding die to melt the binder layer into an adhesive agent to adhere the ink layer and a molded resin layer so as to enwrap the film on the outer circumferential side surface of the product with the film, wherein the circumferential bending amount (a) is set greater than a variation (A) of a thermal shrinkage amount of the film caused by pre-heating the film in the forming process.
