Daiamet Co., Ltd. will exhibit at the "Automotive Technology Exhibition 2026 YOKOHAMA," held at Pacifico Yokohama from May 27 (Wednesday) to 29 (Friday), showcasing the "sintered spur gear for EV cooling modules using high-density heat treatment materials," which is mounted on the cooling module for BEVs (Battery Electric Vehicles) that won the Japan Powder Metallurgy Association's 2025 Industrial Association Award (New Product Design Category). This product is a spur gear used in the valve for switching the flow path of the cooling module for BEVs. By combining sintered materials with unique heat treatment technology, it achieves both high strength and high airtightness, addressing the issues of strength and wear resistance that were challenges with resin gears. Additionally, to tackle the airtightness issues caused by the pores inherent in sintered parts, high airtightness has been secured by optimizing the steam treatment conditions, enabling mass production. This technology is expected to see further adoption as the BEV cooling module market expands. At the venue, we will introduce a wide range of our products and technologies, including the newly exhibited sintered spur gear for EV cooling modules, cores for servo motors, various motor cores, transformers for DC-DC converters, sintered mechanical parts, and sintered oil-impregnated bearings.

Challenging the rapidly growing DCDC converter market driven by the expansion of the AI and EV markets ~ Accelerating the development of the North American market with the next-generation insulated "TriMagiC Converter" ~ Daiyamet Co., Ltd. (Headquarters: Higashi-ku, Niigata City; President: Hiroshi Iii) will intensify its efforts to develop the North American market, leveraging its core strength in next-generation insulated DCDC converter circuit technology, the "TriMagiC Converter." The company will exhibit at APEC 2026, one of the world's largest international conferences on power electronics, held in San Antonio, Texas, USA, from March 22 (Sunday) to March 26 (Thursday), 2026. At the exhibition booth, various prototype circuit boards (PoL, 1.6kW, 3.3kW models) featuring the circuit technology of the "TriMagiC Converter," equipped with the company's powder core in the transformer, will be displayed, along with powder core products for transformers and resonant coils. Additionally, case studies of PoL converters resulting from collaborative research with the Yamamoto Laboratory at the Institute of Future Materials and Systems, Nagoya University, National Institutes for the Humanities, will also be introduced. Furthermore, a seminar for exhibitors will be held. Please refer to the attached file for details.

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.
