Daisin

What Daisin does

Daisin Co.,Ltd is a Thai-incorporated private aluminum die-casting manufacturer founded in 1979, supplying precision metal components to Japanese automotive OEMs with production operations in Thailand. The company operates three manufacturing plants — its headquarters and first plant in Navanakorn (Pathumthani), a second in Korat (Nakhon Ratchasima), and a third in Khonkaen — and employs between 1,001 and 5,000 people. Ownership is structured 77% Thai / 23% Japanese, with a management team dominated by the Leegomonchai family and including a Japanese director, reflecting the company's deep commercial ties to Japanese OEMs.

Daisin's product portfolio is organized into four core lines: Motorcycle Parts, Automobile Parts, PE (Power Equipment) Parts, and EV Parts. Its underlying technology combines High Pressure Die Casting (HPDC) thin-surface capability, conventional die casting, sand-core Gravity Die Casting (GDC), Karakuri automated manufacturing systems, robotic automation, and in-house mold design engineering. Quality and environmental management systems are certified to IATF 16949:2016 and ISO 14001:2015 across all plants. The customer base includes approximately 20 named Japanese enterprise OEMs (Honda, Toyota Daihatsu, Mitsubishi, Isuzu, Hino, Suzuki, Yamaha, Kawasaki, DENSO, Hitachi Astemo, JTEKT, TAIHO, Thai KOITO, T.RAD, IHI Turbo) plus SIAM KUBOTA in agricultural machinery.

Revenue is generated entirely through B2B direct OEM supply on long-term contracts; pricing is not publicly disclosed. Distribution is direct-to-enterprise rather than channel-mediated, and the company's marketing footprint is limited to a corporate website and occasional industry events (e.g., SMC Open House 2023). The EV Parts line, publicly listed but marked "Coming Soon," is positioned as the strategic growth lever for the 2024-2026 mission cycle. Overall, Daisin functions as a mature, certified, multi-plant tier-1/tier-2 incumbent executing a deliberate — but early-stage — pivot from internal-combustion to electrified vehicle components.
