Two decades of precision engineering, serving global OEMs from the heart of China's manufacturing hub
Every automotive part that rolls off the production line begins its life inside a die. The quality of that die determines the fit, finish, and structural integrity of the final component. For more than 20 years, LINHAI DIAN MOULD CO., LTD (Dian Stamping) has been the invisible force behind millions of stamped parts used by some of the world's most demanding automakers. Headquartered in Huangyan, Taizhou, Zhejiang Province 鈥?a region renowned for its mould-making heritage 鈥?the company has earned its reputation as a reliable partner for automotive stamping dies, precision checking fixture solutions, and durable welding jig systems.
A Company Built on Experience
Established in 2003, Dian Stamping has grown from a small workshop into a comprehensive die-making enterprise spanning 50,000 square meters 鈥?including a dedicated 4,000-square-meter die workshop. With approximately 110 employees and a team of 35 experienced die designers, the company delivers roughly 2,000 sets of medium and small stamping dies each year, generating an annual die turnover of approximately RMB 50 million.
These numbers are not just statistics; they reflect a disciplined operation that serves OEMs including KIA, BYD, Toyota, Honda, Suzuki, and Geely, with products exported to more than 10 countries across Asia, Europe, and the Americas.
