The company's core product portfolio includes flexible and rigid busbars used for high-voltage electrical interconnections in electric vehicle (EV) battery packs; integrated busbar assemblies equipped with temperature and voltage sensing lines; battery module cases, end plates, and side plates; battery disconnect unit (BDU) components; and thermal management structures, including liquid cooling plates. Within the ESS segment, the company manufactures high-capacity ESS module housings, containerized rack assemblies, and related structural enclosures. In its precision electronics division, it produces stamped metal components, camera module brackets, display connector parts, and automotive sensor housings. Shinsung ST Co., Ltd. supplies its products to tier-one lithium-ion battery manufacturers and automotive original equipment manufacturers across South Korea, Europe, and North America. In recent developments following its initial public offering on the KOSDAQ market in late 2023, the company has expanded its global production footprint by establishing and ramping up specialized overseas manufacturing facilities in Poland and the United States to localize supply chains for North American and European EV and ESS programs. Additionally, the company has advanced its technical offerings through the commercialization of next-generation flexible printed circuit (FPC) integrated busbars and modular liquid-cooled ESS containment systems to broaden its long-term customer engagements.
