Abstract
Recent trends of miniaturization and multi-functionality in electrical parts have driven the development of molded interconnect devices (MIDs) that contain conductive tracks on a nonconductive base. This study aims to develop a plastic-metal hybrid molding technology for the fabrication of MIDs in a single manufacturing process, by connecting the plastic injection molding and metal casting processes. An embedded mold heating unit was designed to be inserted in the casting section in order to obtain the desirable temperature distribution; the casting section should be heated to near the melting temperature of the metal alloy while the injection molding section should be cooled below the softening temperature of the plastic. To meet these requirements, various embedded heating structures were investigated numerically regarding heating characteristics and structural safety. The numerical analysis results were then verified through experimental validation.
