- Sangsin Energy Display Precision Co., Ltd., doing business as Sangsin EDP Co., Ltd., is a South Korea-based precision manufacturing company primarily engaged in the development, fabrication, and distribution of structural components for secondary lithium-ion batteries. Founded in 1985 and headquartered in Cheonan-si, South Korea, the company specializes in precision deep-drawing and progressive stamping technologies to serve global battery cell producers, electric vehicle (EV) manufacturers, energy storage system (ESS) integrators, and consumer electronics brands. The company's core product portfolio comprises: prismatic battery cans, consisting of deep-drawn rectangular aluminum enclosures and structural casings engineered for mid-to-large-format cells in electric vehicles (xEV) and grid-scale energy storage systems; cylindrical battery cans, comprising precision-formed metal housings across standard form factors (including 18650 and 21700) utilized in power tools, laptops, smartphones, e-mobility devices, and aerospace drones; and cap assemblies, featuring integrated cell-sealing units equipped with cathode pins, insulating gaskets, terminal plates, and current interrupt safety vent mechanisms that prevent cell deformation and thermal runaway. The company conducts its worldwide operations through domestic production sites in Cheonan, Yangsan, and Hwaseong, alongside global manufacturing subsidiaries including Sangsin Hungary Kft. in Jaszbereny, Hungary; Sangsin Indiana Inc. in Kokomo, Indiana, United States; Sangsin Enertech Sdn. Bhd. in Seremban, Malaysia; and Tianjin Taeshin Electronics Co., Ltd. and Xi'an Sangsin Hi-Tech Co., Ltd. in China. In recent developments, Sangsin EDP has strategically expanded its overseas operational footprint and product line capabilities to support major battery manufacturing hubs. The company operationalized and scaled its North American subsidiary, Sangsin Indiana Inc., installing dedicated automated production lines in Kokomo to supply prismatic cans and casing components for North American electric vehicle battery and battery energy storage system (BESS) joint ventures, primarily aligned with Samsung SDI. In addition, Sangsin EDP expanded production capacity at its Jaszbereny facility in Hungary to address European automotive supply requirements and advanced its engineering programs for next-generation 46-series (such as 4680 and 4695) large-diameter cylindrical battery cans and specialized lithium iron phosphate (LFP) enclosure architectures.
