Focus on auto‑suspension R&D & custom build, deliver durable chassis solutions
About Our Company
Yantai Chenyu Auto Parts Co., Ltd. originated as the Changdao Agricultural Machinery Factory (a state-owned enterprise with semi-military production capabilities). After a period operating as Changdao High-Energy Polyurethane Co., Ltd., the company was formally established under its current name in 2012. Originally located in Changdao, Yantai, the company relocated to No. 156 Fenghuangshan Road, Fushan District, Yantai City; the new facility covers an area of 45 mu (approximately 30,000 square meters), with a Phase I factory building spanning 6,000 square meters. Building upon technical expertise in polyurethane products accumulated since 1983, the company now specializes in the R&D and manufacturing of automotive components such as torque rods, reaction rods, and balance shaft bushings.
Yantai Huiyu New Material Technology Co., Ltd., a subsidiary of Yantai Chenyu Auto Parts Co., Ltd., handles sales and trading operations for products related to the parent company.
