【発明の詳細な説明】 〔産業上の利用分野〕 本発明は樹脂材料と低融点金属材料からなる複合成形品
を成形するための複合成形品の成形方法に関する。TECHNICAL FIELD The present invention relates to a method for molding a composite molded article for molding a composite molded article composed of a resin material and a low melting point metal material.

〔従来の技術〕[Conventional technology]

一般に、金属素材は電気的特性及び機械的特性等に優

金属箔の貼付等による電磁波シールドを形成した複合部
材として構成していた。Generally, a metal material is excellent in electrical characteristics and mechanical characteristics, and a plastic material is excellent in appearance and lightness. For this reason, recently, there is an increasing need for a composite material having both properties. For example, since an unnecessary electromagnetic wave is leaked from an electronic device using a digital signal such as a computer, the external case is required to have an electromagnetic wave shielding function in addition to the function as the original case. Therefore, this kind of outer case is applied to the entire inner surface of the plastic case body with conductive paint, surface treatment by plating,
It was configured as a composite member in which an electromagnetic wave shield was formed by sticking a metal foil or the like.

しかし、このような複合部材の製造方法はケース本体を
プラスチックで成形する成形工程と、さらに電磁波シー
ルドを形成する製造工程を要するなど、全く異なる二つ
の製造プロセスを必要とするため、生産性が悪く、製造
上の著しいコスト上昇を招くとともに、電磁波シールド
材の剥離や錆等の経時劣化を生ずる問題があった。However, the manufacturing method of such a composite member requires two completely different manufacturing processes, such as a molding process of molding the case body with plastic and a manufacturing process of further forming an electromagnetic wave shield, resulting in poor productivity. However, there has been a problem that the manufacturing cost is significantly increased and that the electromagnetic wave shielding material is deteriorated with time such as peeling and rust.

このため、従来では生産効率及び経済性をより高め得る

成形する製造方法も特公平2-25772号公報で提案されて
いる。For this reason, conventionally, as a manufacturing method capable of further increasing production efficiency and economical efficiency, molten low-melting-point metal is continuously injected into a flux of a thermoplastic resin through a molten metal injection slit provided in a die. However, a manufacturing method in which a thermoplastic resin is extruded and molded is also proposed in Japanese Patent Publication No. 25772/1990.

〔発明が解決しようとする課題〕[Problems to be Solved by the Invention]

しかし、このような従来の製造方法は金属層がプラスチ

の経時劣化から保護できる利点はあるものの、成形され
る複合成形品（複合部材）はシート状のため、二次加工
の形状にも限界があるなど、その応用範囲が極めて狭
く、実用性に欠ける難点があった。However, such a conventional manufacturing method is efficient and economical because the metal layer is formed inside the plastic and is produced in a single molding step, and the metal layer is resistant to deterioration over time such as peeling. Although there is an advantage that it can be protected, the composite molded product (composite member) to be molded is in the form of a sheet, so there is a limit in the shape of the secondary processing, so its application range is extremely narrow, and there is a problem that it is not practical. .

本発明はこのような従来の技術に存在する課題を解決し

である。The present invention has solved the problems existing in such conventional techniques, and an object thereof is to provide a molding method of a composite molded article, which can improve the molding efficiency and the versatility.
