Aisin Automotive Casting

What Aisin Automotive Casting does

Aisin Automotive Casting, LLC (AAC) is a privately held Kentucky-domiciled limited liability company that operates two die-cast manufacturing plants in London, Kentucky under the corporate umbrella of Japan's Aisin Group. Founded in November 1996 with $72.1 million in stated capital, AAC runs an integrated turn-key production system that encompasses melt processing, die casting, machining, heat treatment, and final assembly of automotive powertrain components.

AAC's product portfolio is concentrated in three core categories—engine components (water pumps, oil pumps, crankcases, timing chain covers, cam carrier housings), transmission components (valve bodies, transmission cases, torque converter housings, stator wheels), and transaxle components (transaxle cases, extension housings, adaptors), along with brake components such as master cylinder bodies. Approximately 700 employees support operations that supply directly to major North American automotive OEMs including Toyota Motor Manufacturing, General Motors, Honda Motor Company, and Nissan, with additional volume routed to Aisin Group affiliates (OTICS, ADI, ANC, ATX). Reference programs include Toyota Camry, Tundra, Tacoma, and Sienna; Chevrolet Silverado, SUV, and Corvette; and Honda Accord.

Revenue is generated through long-term OEM supply contracts under confidential pricing, with demand tied to vehicle production volumes at customer plants. Distribution is exclusively direct-to-OEM, and the company does not publicly disclose financials. Strategic posture emphasizes a "Quality First" operating philosophy, evidenced by a multi-year run of Toyota Delivery and Quality Excellence Awards and recognition from Aisin Warner North Carolina and DENSO between 2005 and 2009.
