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.

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.

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 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.

Starting from September 22, 2025 (Monday), we will begin accepting orders for five new lineups tailored to various applications in the "N-SELECT" series of transport vehicles. In this new development, we will introduce the following five models that maintain the basic performance of the traditional N-SELECT while addressing more specialized needs: SC (Super Carrier) - Based on the traditional N-SELECT, this model is specialized for transporting immobile and accident vehicles. It is ideal for the automotive maintenance and towing industry. RC (Racing Carrier) - Designed with a gentle loading and unloading angle, this model is perfect for transporting sports cars and lowered vehicles. TP (Transporter) - A standard model optimized for the transportation of general passenger vehicles, suitable for a wide range of industries. ONE (Single Vehicle Loading Model) - A simple and efficient design dedicated to loading one vehicle. Recommended for small-scale transport and individual entrepreneurs. RS (Rescue) - A single vehicle loading model equipped with a crane, enhancing its capability to respond in accident scenes and tight spaces. With these lineups, N-SELECT evolves into a product group that meets a wider variety of on-site needs. We will continue to promote product development that reflects the voices from the field as the "preferred transport vehicle."
