What Seojincam does

Seojincam (SECO 서진캠) is a South Korea-based automotive components manufacturer, publicly listed as a stock company (주식회사 서진캠) and a subsidiary of SJ Holdings (에스제이홀딩스) within the broader SECO Group. Founded in 1999 from the camshaft division of Seojin Industrial, the company operates three integrated Korean manufacturing plants — Pyeongtaek (headquarters), Asan (second plant, completed 2011), and Dangjin (third plant, completed November 2017) — along with an R&D center in Gunpo (established May 2000) and a Zhangjiagang (China) operating subsidiary. The company employs 337 people, of whom 304 are in management/production and 33 in R&D, and serves automotive OEMs and tier-1 suppliers in Korea, North America, China, Europe (Czech Republic), Mexico, and Vietnam.

The company's core product is the hollow-sintered camshaft, manufactured via a proprietary powder-metal sintering process that achieves a 30-50% weight reduction versus conventional iron-cast camshafts. Product lines are organized into three categories: Camshaft (gasoline, diesel, and commercial engine applications), Electrification (EV motor cores for e-AWD 90kW/250kW systems, HEV motor cores for TMED-2 platforms, and battery cooling fans), and Advanced Development (pre-production EV drive motors of 25kW and 80kW, AMR drive motors of 1-10kW, 190W actuator motors, and 120W blower motors). In-house engineering capability is supported by a CAE toolchain including Pro Engineer, Uni-Graphics (GM Supplier Engineering Bundle), NX Nastran, DEFORM, AVL Excite Timing Drive, and CETOL for valve train dynamics simulation.

Revenue is generated almost exclusively through direct B2B hardware sales to automotive OEMs and tier-1 suppliers under long-term supply contracts and RFQ-driven new business processes, with pricing not publicly disclosed. Customer concentration is anchored in the Hyundai Motor Group ecosystem (Hyundai Motor, Kia, Hyundai Mobis, Hyundai WIA, Hyundai GLOVIS) and extends to General Motors, FCA/Stellantis, and Mahindra. Quality system certifications include IATF 16949 (via ISO/TS 16949 lineage), ISO 14001, OHSAS 18001, and Single PPM. Notable recognition includes the 2021 $200 Million Export Tower award (58th Trade Day), the 2019 Hyundai Motor Group Partner of the Year (Technology Sector), and the 2025 GM Outstanding Partner Award. In September 2025 the company announced a small-scale merger with parent SJ Holdings.

Core offering

Seojincam designs and manufactures hollow-sintered camshafts using a proprietary powder-metal sintering process for gasoline, diesel, and commercial engines, delivering 30-50% weight reduction versus conventional iron-cast camshafts. The company also produces EV/HEV motor cores (rotor assemblies for e-AWD and TMED-2 platforms), battery cooling fans, and pre-development drive/actuator motors for automotive OEMs and tier-1 suppliers.

Product overview

Seojincam (SECO) is an automotive parts manufacturer organized around three core product lines. The flagship product is the Hollow-Sintered Camshaft — a specialty camshaft manufactured using a proprietary powder-metal sintering process, applied to gasoline, diesel, commercial, and module engine applications, offering 30–50% weight reduction versus conventional cast designs. The second product line is Electrification (전동화), covering EV and HEV motor core assemblies (rotor stacks) for e-AWD and TMED-2 platforms, and battery cooling fans for hybrid vehicles. The third line is Advanced Development (선행개발), focused on pre-production motor and actuator products including EV drive motors (80kW, 25kW), AMR drive motors (1–10kW), actuator motors (190W), and blower motors (120W). Together these three lines serve both traditional powertrain and emerging electrified vehicle markets, with R&D support through the company's design and test equipment infrastructure.
