2025 Yokohama Automotive Technology Exhibition Participation

Developed a resin that balances heat dissipation and electromagnetic wave shielding! Achieved approximately 45% weight reduction by converting from metal to resin.

【People and Cars Technology Exhibition YOKOHAMA】 Date: May 21 to 23 Location: Pacifico Yokohama Exhibition Hall 351 (inside the Sekisui Chemical booth) Real resin samples will be on display, so please come and visit. With the electrification of automobiles, the challenge is to "lighten the body and extend the driving range," and the demand for lightweight materials is significantly increasing across the industry. Sekisui Techno Molding's approach contributes to weight reduction and cost savings by converting metal to resin. In cases of the same shape, this results in approximately 45% weight reduction compared to metal. While many resin products show a significant decrease in heat dissipation and are inferior in controlling electromagnetic waves (noise) compared to metal, Sekisui Techno Molding's resin products ensure these functions. - Heat Dissipation Focused Type - ■ Heat Conductive Resin Molded Products - Reduction of product temperature rise due to heat diffusion - Weight reduction, improved design flexibility, and mass production by replacing metal products - Heat Dissipation and Electromagnetic Wave Shielding Compatible Type - ■ Heat Dissipation and Electromagnetic Wave Shielding Resin Molded Products - Reduction of product temperature rise due to heat diffusion - Electromagnetic wave shielding performance through conductivity - Weight reduction, improved design flexibility, and mass production by replacing metal products

Currently, metal housings/cases are mainstream for vehicle-mounted ECUs. By changing this to resin, weight reduction and cost savings can be achieved.

In-vehicle ECUs typically use metal cases made of aluminum or copper. While metal shielding ensures robustness and excellent EMC measures, it poses significant challenges in terms of weight and cost. With the electrification of vehicles, the imperative of "how to lighten the body and extend the driving range" is unavoidable, and the demand for lightweight solutions is high. Sekisui Techno Molding's approach enables weight reduction by converting from metal to resin (approximately 45% reduction for the same shape). It also allows for design freedom through resin molding and cost reduction via mass production. While many resin products are inferior to metals in terms of heat dissipation and electromagnetic wave (noise) control, Sekisui Techno Molding's resin products ensure these functions. ■ Thermally conductive resin molded products (focused on heat dissipation) - Reduction of product temperature rise through heat diffusion - Weight reduction, improved design freedom, and mass production by replacing metal products ■ Heat dissipation and electromagnetic wave shielding resin molded products (balancing heat dissipation and electromagnetic wave shielding) - Reduction of product temperature rise through heat diffusion - Electromagnetic wave shielding performance through conductivity - Weight reduction, improved design freedom, and mass production by replacing metal products With Sekisui Techno Molding's comprehensive system, we consistently support our customers from planning and prototype development/verification to mass production and sales to realize their ideals.

If it is a heat-dissipating and electromagnetic wave shielding resin molded product, EMC measures essential for e-Axle and on-board chargers (OBC) can also be achieved.

The electrification of automobiles requires EMC design that is more conscious of "emissions (electromagnetic interference/EMI)" and "immunity (electromagnetic susceptibility/EMS)" because they operate at high voltage and large current compared to ICE vehicles. Additionally, the challenge of "how to reduce vehicle weight and extend driving range" has become a key issue, leading to a significant increase in the demand for lightweight solutions across the industry. Sekisui Techno Molding's approach involves lightweighting through the conversion from metal to resin, which also contributes to cost reduction. In cases of the same shape, this results in approximately 45% weight reduction compared to metal. While many resin products suffer from significantly reduced heat dissipation and inferior electromagnetic wave (noise) control compared to metal, Sekisui Techno Molding's resin products ensure these functionalities. - A type that balances heat dissipation and electromagnetic wave shielding - ■ Heat dissipation and electromagnetic wave shielding resin molded products - Reduction of product temperature rise through heat diffusion - Electromagnetic wave shielding performance through conductivity - Lightweighting, increased design freedom, and mass production by replacing metal products With Sekisui Techno Molding's comprehensive system, we consistently support our customers from product planning to prototype development/testing, and then to mass production and sales, ensuring they achieve their ideal products.

Proposal for resin molded products that ensure heat dissipation and electromagnetic wave shielding performance for vehicle-mounted cameras, millimeter-wave radar, and LiDAR housings.

Recently, the technologies of "Advanced Driver Assistance Systems (ADAS)" and "Autonomous Driving (AD)" have been steadily evolving. To ensure the stable operation of key technologies and important safety components such as "onboard cameras," "LiDAR," and "millimeter-wave radar," EMC (Electromagnetic Compatibility) measures have become a significant challenge. Sekisui Techno Molding's approach enables many resin products, which are inferior to metals in terms of heat dissipation and electromagnetic wave (noise) control, to achieve weight reduction and design flexibility through resin molding while ensuring these functionalities, leading to cost reductions through mass production. ■ Heat-conductive resin molded products (focused on heat dissipation) - Reduction of product temperature rise through heat diffusion - Weight reduction, improved design flexibility, and mass production by replacing metal products ■ Heat dissipation and electromagnetic wave shielding resin molded products (balancing heat dissipation and electromagnetic wave shielding) - Reduction of product temperature rise through heat diffusion - Electromagnetic wave shielding performance through conductivity enhancement - Weight reduction, improved design flexibility, and mass production by replacing metal products With Sekisui Techno Molding's comprehensive system, we consistently support our customers from planning and prototype development/verification to mass production and sales to realize their ideals.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
