Abstract
A method of manufacturing an in-mold decorative molded article includes supplying an in-mold transfer foil to a metal mold, injecting and cooling a molding resin and taking out an molded article formed of the molding resin cooled and cured in the metal mold in which a clear layer and a transfer layer having a decorative figure in the in-mold transfer foil are integrated on the surface by opening the mold, molding the molded article integrally with a cutting portion not necessary for a target product inside the metal mold by the molding resin at an outer periphery of the product and arranging a boundary of a printing region of the clear layer in the in-mold transfer foil in the cutting portion so as to be larger than the outer periphery of the product.
Claims5
A method of manufacturing an in-mold molded article, the method comprising:
- supplying an in-mold transfer foil to a metal mold, the in-mold transfer foil including a clear layer formed in a first layer on an in-mold raw fabric that is configured by forming a mold releasing layer and a primer layer on a base material film, the clear layer having transparency and lower extensibility than the base material film, and a pattern is printed in second and subsequent layers on the in-mold raw fabric;
- clamping the metal mold, injecting and cooling a molding resin, and taking out a molded article formed of the molding resin that has cooled and cured in the metal mold, wherein the clear layer and a transfer layer having the pattern in the in-mold transfer foil are integrated on a surface of the molded article by opening the mold;
- molding the molded article integrally with a cutting portion inside the metal mold by the molding resin at an outer periphery of a target product, wherein the cutting portion is not necessary for the product;
- and
- arranging a boundary of a printing region of the clear layer in the in-mold transfer foil in the cutting portion so as to be larger than the outer periphery of the product.
A method of manufacturing an in-mold molded article, the method comprising:
- forming an in-mold transfer foil in which a clear layer is formed in a first layer on an in-mold raw fabric that is configured by forming a mold releasing layer and a primer layer on a base material film,
- wherein the clear layer is formed by using curable ink, and, in second and subsequent layers on the in-mold raw fabric, a layer in which a frame pattern is formed, a non-printing region is included, and all printing layers necessary for design expression are formed,
- wherein the second and subsequent layers are printed in a smaller region than a size of the molded article;
- forming a cutting portion larger than a product size in an outer peripheral portion of the molded article so as to be larger than a printing region of the layer in which the frame pattern is formed so as to obtain a product shape by cutting;
- and
- arranging the layer in which the frame pattern is formed so that a boundary of the printing region is positioned in the cutting portion.
