Injection-molded resin optimal for heat dissipation and EMC measures for various EV-related automotive components.
- Heat-conducting resin molded products - Heat dissipation and electromagnetic wave shielding resin molded products
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.
