New investment in Indiana strengthens advanced manufacturing and supports the growing electric vehicle supply chain
Springfield, Indiana, 17 July 2026 – As the automotive industry accelerates toward electrification, manufacturers are investing in new technologies that improve vehicle performance and strengthen domestic production. Aisin USA Manufacturing has taken another step in that direction by launching a new cooling plate manufacturing line at its facility in Seymour, Indiana. The expansion reflects the company’s continued investment in advanced manufacturing and supports the growing demand for electric vehicle components across North America.
The new production line is dedicated to manufacturing aluminum cooling plates, which play an essential role in battery thermal management systems for electric and hybrid vehicles. These components help regulate battery temperature, allowing batteries to perform more efficiently, charge faster, last longer, and operate more safely under different driving conditions. As electric vehicles become more common, thermal management technology is becoming one of the most important aspects of modern automotive engineering.
The investment also highlights the growing importance of local manufacturing. Producing advanced automotive components closer to customers helps manufacturers improve supply chain reliability, shorten delivery times, and respond more quickly to market demand. With automakers expanding electric vehicle production across North America, suppliers are increasingly strengthening their regional manufacturing capabilities to support future growth.
The Seymour facility uses advanced production technologies, including precision aluminum forming, automated manufacturing systems, brazing processes, leak testing, and detailed quality inspections. These manufacturing techniques help ensure that every cooling plate meets strict quality and performance standards before reaching vehicle manufacturers. Automation also increases production flexibility, allowing the facility to efficiently support multiple customer programs while maintaining consistent product quality.
Beyond expanding production, the project reinforces Indiana’s position as a leading center for automotive manufacturing in the United States. The state has become home to numerous automotive manufacturers and suppliers investing in next-generation mobility solutions, including electric powertrains, battery systems, and advanced vehicle technologies. Continued investments like this contribute to regional economic growth while supporting skilled manufacturing jobs and technological innovation.
The expansion is also part of Aisin’s broader strategy to support the future of mobility. As vehicle manufacturers continue introducing new electric and hybrid models, demand for efficient thermal management systems is expected to grow significantly. Cooling plates help maintain stable battery temperatures during charging and operation, improving battery efficiency while extending overall vehicle life. These systems are becoming increasingly important as consumers expect longer driving ranges, faster charging times, and improved reliability from electric vehicles.
Industry experts believe investments in advanced manufacturing technologies will remain a key driver of competitiveness in the global automotive market. Companies that combine automation, precision engineering, and localized production are better positioned to respond to evolving customer needs while strengthening supply chain resilience. As electrification continues to reshape the automotive industry, facilities capable of producing high-quality battery components will play an increasingly important role in supporting future vehicle production.
With its latest manufacturing expansion, Aisin demonstrates how strategic investments in advanced production technologies can help meet the changing needs of the automotive industry. The new cooling plate production line not only supports the transition toward cleaner mobility but also reinforces the importance of innovation, manufacturing excellence, and domestic production in building the next generation of transportation.
