Abstract

PURPOSE:To easily obtain the titled molded article even when the molded article has a three-dimensional surface and without requiring any pretreatment of the molded article, by a method wherein a thin metallic film is formed, then it is set in a mold, and a molding material is injection-molded to be integrated with the metallic film. CONSTITUTION:The thin metallic film (preferably, a thin aluminum film having a thickness of 0.01-10mu) is formed by pressing, vacuum forming, air pressure forming or the like. The thus formed metallic film is coated with an adhesive, as required, and is set in the mold. Then, injection molding is conducted to obtain the objective molded article.

では製造の効率が悪く、金属の過大な重量が軽量化の要
望に沿えないためである。Various methods are used to coat the surface of synthetic resin molded bodies, and in particular, there is a growing demand for metallic-like expression. This is because cutting or casting the metal itself is inefficient in manufacturing, and the excessive weight of the metal does not meet the demand for weight reduction.

式の適用は困難である。Methods for imparting a metallic appearance to the surface of a molded object include, for example, electroless plating and transfer methods, but when electroless plating is used, wet steps such as pretreatment of the molded object and plating are required. There is a complexity that requires related peripheral equipment such as waste liquid treatment, and even if you try to give a metallic appearance to a molded object using a transfer method, it is difficult to apply the transfer method to a three-dimensional curved surface, let alone a flat or quadratic curved surface. It is.

本発明は上記の従来の技術の欠点を解消することを目的
とする。The present invention aims to overcome the drawbacks of the prior art described above.

This invention relates to a method for producing a molded body coated with a metal thin film.

まず本発明においては金属薄膜を準備する。First, in the present invention, a metal thin film is prepared.

状のものやホットメルト型のものも使用できる。A heat-sensitive and/or pressure-sensitive adhesive may be applied to the metal thin film in advance to increase its adhesion to the injection molded resin.
Further, the opposite side may be coated with a synthetic resin layer for the purpose of protecting the surface of the final product. Film adhesives and hot melt adhesives can also be used.

上記の金属薄膜は適宜な剥離性基体上に仮接着されてい

感圧性接着剤や合成樹脂層を設けてもよい。The above metal thin film may be temporarily adhered onto a suitable releasable substrate, and at this time, the above-mentioned heat-sensitive and/or pressure-sensitive adhesive or synthetic resin layer may be provided.

レーティング等によって形成してもよい。The metal thin film may be a pre-manufactured metal foil, but when provided on a removable substrate, it may be formed by vapor deposition, sputtering, ion blasting, or the like.

次に上記の金属薄膜を所定の形状に成形する。Next, the metal thin film described above is formed into a predetermined shape.

同時に行なってもよい。Shaping is performed by pressing, cold working, etc. In the case of a metal thin film formed on a releasable substrate, the molding of the releasable substrate may be used. It is desirable that the degree of molding be the same as that of the injection mold described below, but if the metal thin film is malleable and molded at the pressure and temperature used during injection molding, the shape will be similar to g. Alternatively, depending on the shape, the metal thin film may be formed substantially simultaneously during injection molding without being pre-molded.

得る。The formed metal thin film obtained above is set in a mold, and then injection molding is performed to obtain a formed body having a metal-like appearance in which the metal thin film is coated along the shape of the formed body.

以上の本発明によれば、各工程自体は既存の設備を利用
