DIAMET CORPORATION Company Profile

Daiamet Co., Ltd. will exhibit at the "TECHNO-FRONTIER 2025 40th Power System Exhibition" held at Tokyo Big Sight from July 23 (Wednesday) to July 25 (Friday), 2025. At this exhibition, we will introduce various prototype boards and core products, focusing on our unique magnetic material "Powder Core (MBS)" combined with circuit technology, featuring the new insulated DC-DC converter "TriMagiC Converter." Particularly noteworthy is the prototype unit achieving a conversion efficiency of 97.2%, which will be unveiled for the first time, with a power output of 1.6kW. Additionally, we plan to introduce the PoL converter, which we have recently begun joint research on with Nagoya University. Furthermore, during the exhibition, our senior advisor and developer, Mitsuaki Fujimoto, will provide a technical explanation of the new technology "TriMagiC Converter" in a seminar for exhibitors. This seminar will clearly present the technology of insulated DC-DC converters that achieve unprecedented miniaturization and high efficiency through the use of magnetic cores with low permeability and high saturation magnetic flux density, covering the background of development, operating principles, and prototype examples. We sincerely look forward to your visit.

Daiamet Co., Ltd. will exhibit at the "Automotive Technology Exhibition 2025 YOKOHAMA," which will be held at Pacifico Yokohama from May 21 (Wednesday) to May 23 (Friday), showcasing our latest technologies in sintered machine parts and sintered oil-impregnated bearings, as well as our new insulated DCDC converter circuit technology "TriMagiC Converter (TM)" that simultaneously achieves high power, high conversion efficiency, and miniaturization. The "TriMagiC Converter (TM)" utilizes our proprietary magnetic material "Powder Core (MBS (TM))" for transformers and resonant coils, combined with our uniquely developed high-performance insulated DCDC converter circuit technology, resulting in significant miniaturization and efficiency improvements compared to conventional circuits. We will display a circuit board (prototype) equipped with this technology at the venue. Additionally, we plan to showcase a thin motor, the "Axial Flux Motor," which also applies the Powder Core (MBS (TM)) and achieves both high torque and high efficiency. This motor is a next-generation type expected to be applied in electric vehicles (EVs) and industrial robots. We sincerely look forward to your visit.

Daiamet Co., Ltd. will serve as a platinum sponsor at the international conference "WORLD PM2024," organized by the Japan Powder Metallurgy Association, to be held at Pacifico Yokohama, and will also exhibit at the exhibition during the event. At the exhibition, we will primarily showcase our new soft magnetic material products that we are challenging. In particular, we plan to display prototypes of circuit boards using our unique magnetic material: powder compacted cores (MBSTM), as well as high-torque, high-efficiency thin axial gap motors for electric vehicles (EVs) and industrial robots, showcasing the results of our advanced technology development. We hope that all attendees will experience Daiamet's future-oriented vision and have the opportunity to exchange ideas about new collaboration possibilities. Please feel free to stop by.
