複合材AM を用いたインサート射出成形技術の開発

抄録

Composite additive manufacturing (AM) can form complex shapes that are impossible to achieve by conventional machining methods, and thus it is expected to contribute to the fabrication of value-added products. However, AM has disadvantages such as long cycling time in manufacturing, high material cost, and low material strength. Therefore, we developed a manufacturing method that combines AM and injection molding, which are extensively used as rapid and inexpensive manufacturing processes. In this study, after designing the structure and molding conditions to prevent AM insert breakage, injection molding and quality confirmation tests were performed to verify the feasibility of this manufacturing process.
