NSC

What NSC does

NSC Co., Ltd. (株式会社エヌエスシイ) is a Japanese family-owned precision aluminum die-cast manufacturer serving global automotive OEMs and Tier 1/2 suppliers. Founded in 1966 as an aluminum casting processing business in Osaka, the company was reorganized as Shin-Ei Die Cast Kogyo in 1985 and re-launched as NSC Co., Ltd. in 2002. Its core competency is ultra-thin and high-pressure-resistant aluminum die-cast components for steering (pinion, gear, valve housings, steering bodies), car air-conditioning compressors, engine parts (crankcases, timing chain covers, VTC covers, turbochargers), transmission components (side covers, stators, sleeves), and Plug-in Hybrid Vehicle parts (base plates, air-cooled cases).

NSC operates an integrated one-stop manufacturing model covering mold design, mold manufacturing, casting, and precision machining, supported by simultaneous engineering collaborations with customers from the development stage. The group runs 165 die-cast machines across 7 sites in Japan (Higashi-osaka HQ, Okayama/Mimasaka), China (Dongguan), Thailand (4 plants), and a North American sales office in Atlanta, with monthly aluminum consumption exceeding 2,000 tons. Differentiators include ADSTEFAN-based flow analysis, 5-axis ultra-high-speed mold machining, modular production design, and skilled workforce (24 first-level and 37 second-level certified die-cast technicians).

NSC generates revenue through B2B hardware sales of custom-designed die-cast components via long-term supply agreements with global automotive OEMs and Tier 1 suppliers including Aisin, JTEKT, NSK, Jatco, Nissan, BOSCH, ZF, Astemo, Honda, Mitsubishi Motors, and DENSO. Automotive accounts for 90%+ of group revenue, with historic electronics segments (HDD components) declining to under 10%. Group consolidated revenue is ¥25 billion (~$165M USD); parent-entity NSC standalone revenue is ¥5.06 billion. The company holds ISO9001, ISO14001, and ISO/IATF16949 certifications across all global production sites and is recognized by Japan's METI as one of 300 Excellent Monozukuri SMEs (2006).
