From aluminum extrusion to liquid-cooling expert — we focus on one craft and push it further every year.
Founded in 2008, Shandong Keyuan specializes in precision aluminum extrusion and liquid cooling products.
Over 17 years we've grown from a single aluminum supplier into a one-stop partner spanning battery enclosures, cold plates, cooling units, and pack-level thermal management — serving CRRC, FAW, Shacman, Yutong, Hangcha, Linde and more.
In 2026 our Phase-II factory went live with 300,000 units/year capacity. Products ship to India, Morocco, Russia, Vietnam, and 10+ countries globally.
Large-stroke gantry machining centers and dedicated FSW machines — battery boxes up to 1.8 m, finished in one setup.
