When automotive OEMs search for a manufacturing partner that combines two decades of hands-on experience with modern production scale, one name consistently delivers — DIAN STAMPING (LINHAI DIAN MOULD CO., LTD), a China-based manufacturer providing automotive stamping dies, sheet metal parts, checking fixtures, and welding jigs to customers across more than 10 countries.

A Legacy Built on Precision and Scale

Founded in 2003 in Huangyan, Taizhou, Zhejiang Province, DIAN STAMPING has grown from a specialized tooling workshop into a full-service manufacturing partner. The company's modern facility spans approximately 50,000 m², with a dedicated die workshop of 4,000 m². A planned 35,000 m² expansion featuring new press and coating lines signals the company's commitment to meeting growing global demand.

With around 110 employees — including approximately 35 die designers and technicians — the company achieves an annual capacity of about 2,000 sets of medium and small stamping dies. Its reported annual die turnover of approximately RMB 50 million reflects consistent output trusted by major automotive brands.

DIAN STAMPING specializes in progressive die stamping, transfer dies, and tandem/multi-station dies for complex automotive parts. The company processes a wide range of materials including multiphase steel, aluminum, custom rolled and welded plate, and stainless steel — giving engineers the flexibility to specify the optimal material for each application.

Beyond tooling, DIAN STAMPING offers a complete vertically integrated service chain: tool and die manufacturing, stamping production, welding, assembly, checking fixtures, and welding jigs. This end-to-end approach reduces lead times, eliminates coordination risks, and ensures consistent quality from design through delivery.
