Composite Molded Parts for Automotive Applications

About the product

With the electrification of automobiles, electrical components such as PCUs are required to deliver not only high precision and reliability, but also excellent thermal compatibility and cooling performance.
By combining our proprietary resin formulation and filler compounding technologies with precision injection molding technology, we provide high-precision resin-metal composite molded products.
Through technologies such as integrated cooling and three-dimensional cooling, we achieve high electrical insulation, heat resistance, and cooling performance.
In addition, we ensure consistent quality from prototyping through mass production, contributing to higher performance, smaller size and lighter weight, and greater reliability of electrical components for electric vehicles and next-generation power modules.
