In the highly competitive world of automotive manufacturing, the quality of your tooling directly determines the quality of your final product. Whether you are producing body panels, structural reinforcements, or complex assemblies, partnering with an experienced automotive stamping dies manufacturer can mean the difference between production excellence and costly downtime. One name that has been delivering consistent results for over two decades is LINHAI DIAN MOULD CO., LTD — better known as DIAN STAMPING.

A Legacy of Precision Since 2003

Established in 2003 in Huangyan, Taizhou, Zhejiang Province, DIAN STAMPING has grown from a modest workshop into a full-scale manufacturing facility covering approximately 50,000 m². With a dedicated die workshop of 4,000 m² and a team of around 110 employees — including 35 highly skilled die designers and technicians — the company has built a reputation as one of the most reliable stamping die manufacturers in China.

The company's annual die turnover of approximately RMB 50 million and its capacity to produce about 2,000 sets of medium and small stamping dies per year speak to the scale and maturity of its operations. A new 35,000 m² facility featuring state-of-the-art press and coating lines is already in the pipeline, signaling a strong commitment to continuous growth and technological advancement.

Comprehensive Product and Service Portfolio

Unlike many suppliers who specialize in only one area, DIAN STAMPING offers a truly integrated, one-stop solution. The company's capabilities span the entire manufacturing chain:

• Stamping Dies — Progressive, transfer, and tandem dies for large and medium-sized complex automotive parts, designed for high-volume production with tight tolerances.

• Checking Fixtures — High-precision, GD&T-oriented inspection fixtures that ensure every stamped component meets exact dimensional specifications.
• Welding Jigs — Custom welding fixtures designed for accurate, repeatable positioning and assembly in automotive production lines.

This comprehensive approach means that customers can source tooling, production parts, inspection fixtures, and assembly solutions from a single, accountable partner — reducing lead times, simplifying logistics, and improving overall quality control.
