From Prototype to Production: Dian Stamping Delivers One-Stop Automotive Manufacturing Solutions
20+ years of precision engineering, serving global OEMs from China's manufacturing hub
In the fast-paced world of automotive manufacturing, finding a partner who can handle everything from tooling design to mass production is the difference between a smooth launch and a costly supply chain bottleneck. DIAN STAMPING (LINHAI DIAN MOULD CO., LTD), based in Taizhou, Zhejiang, has been that partner for global automotive OEMs since 2003. With a 50,000 m² facility, over 110 skilled employees, and an annual output of 2,000 sets of stamping dies, the company has earned its reputation as one of China's most reliable stamping die manufacturers.
Company Profile: Built for Scale and Precision
Established in 2003, Dian Stamping operates a modern 50,000 m² manufacturing campus that includes a dedicated 4,000 m² die workshop. The company employs approximately 110 people, among them 35 experienced die designers and technicians. Its annual die-making capacity reaches 2,000 sets of medium and small stamping dies, generating an annual die turnover of approximately RMB 50 million. A newly planned 35,000 m² facility featuring advanced press and coating lines is set to further expand production capacity.
The company's core capability lies in the design and manufacture of automotive stamping dies — including progressive dies, transfer dies, and tandem/multi-station dies — as well as the production of precision sheet metal parts, checking fixtures, and welding jigs. Materials processed include multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel, giving them the flexibility to serve a wide range of automotive applications.
A Complete Product Ecosystem
What sets Dian Stamping apart is its vertically integrated approach. Rather than specializing in just one area, the company offers four interconnected product lines that cover the entire manufacturing lifecycle:
Stamping Dies
Progressive, transfer, and tandem dies for body-in-white, door systems, seating systems, chassis, and more. Precision-engineered for high-volume production.
Sheet Metal Parts
Custom precision sheet metal fabrication parts for automotive and household appliance applications, with welding and assembly services.
Checking Fixtures
GD&T-oriented inspection fixtures that ensure every stamped component meets strict dimensional tolerances before assembly.
Welding Jigs
Custom positioning and welding fixtures designed for accurate, repeatable assembly of complex automotive structures.
Applications Across the Vehicle

Quality Assurance and Customization
Dian Stamping operates under an ISO 9001 quality management system, with processes aligned to IATF 16949-oriented automotive manufacturing standards. Every die and part is subject to rigorous inspection protocols, including CMM (coordinate measuring machine) verification and in-line quality checks.
The company accepts custom orders based on 2D drawings, 3D CAD data, or physical samples. Prototype services are available for new product development.
