In the fast-evolving automotive industry, the quality of every stamped component directly impacts vehicle safety, structural integrity, and production efficiency. Whether you are sourcing tooling for a new vehicle program or looking for a reliable partner for high-volume production of sheet metal parts, choosing the right manufacturing partner is critical. Linhai Dian Mould Co., Ltd (Dian Stamping) has been serving global automotive OEMs and Tier 1 suppliers since 2003, delivering precision-engineered automotive stamping dies, sheet metal components, checking fixtures, and welding jigs from its state-of-the-art facility in Taizhou, Zhejiang, China.
Two Decades of Industry Experience
Established in 2003, Dian Stamping brings more than 20 years of hands-on experience in tool and die manufacturing, metal stamping, welding, and assembly. The company has built long-term partnerships with renowned automotive brands including KIA, BYD, Toyota, Honda, Suzuki, and Geely, and exports its products to over 10 countries worldwide. This track record speaks to the company's consistent quality, on-time delivery, and deep understanding of automotive-grade manufacturing standards.
Comprehensive Manufacturing Capabilities
Dian Stamping operates a modern facility covering approximately 50,000 m², including a dedicated die workshop of about 4,000 m². With around 110 employees — among them 35 experienced die designers and technicians — the company achieves an impressive annual capacity of approximately 2,000 sets of medium and small stamping dies, with an annual die turnover of around RMB 50 million.
The company's progressive die stamping capabilities cover a wide range of die types, including progressive dies, transfer dies, and tandem/multi-station dies. Materials processed include multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel. A planned new 35,000 m² facility featuring new press and coating lines will further expand capacity and capability.

Quality Assurance and Certifications
Dian Stamping operates under an ISO 9001-certified quality management system, with manufacturing practices aligned to IATF 16949 automotive standards. The company implements rigorous quality control throughout the production process, from raw material inspection to final dimensional validation using CMM and other precision measurement tools. Every checking fixture and die set undergoes thorough tryout and inspection before shipment.
