In the fast-evolving world of automotive manufacturing, the quality of your tooling and stamped components directly determines the success of your production line. Choosing the right partner for stamping dies and precision metal parts is not just a procurement decision — it is a strategic move that affects cost, lead time, and product quality across the entire supply chain.

Two Decades of Stamping Excellence

Established in 2004 and headquartered in Linhai, Taizhou, Zhejiang Province, LINHAI DIAN MOULD CO., LTD (branded as DIAN Stamping) has grown from a specialized die workshop into a comprehensive manufacturing powerhouse. With over 20 years of industry experience, the company operates a modern 50,000 m² facility — with an additional 40,000 m² under construction — and employs approximately 110 skilled professionals, including 35 die designers and technicians.

DIAN Stamping has 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. More importantly, the company has earned the trust of global automotive OEMs including KIA, BYD, Toyota, Honda, Suzuki, and Geely, exporting to more than 10 countries worldwide.

Comprehensive One-Stop Manufacturing Services

What sets DIAN Stamping apart is its vertically integrated service model — from tool design and die manufacturing to stamping, welding, coating, and final assembly. This end-to-end capability eliminates the inefficiencies of managing multiple suppliers and ensures consistent quality at every stage of production.

The company's core offerings span four main categories. First, precision stamping dies, including progressive dies, transfer dies, and tandem dies for complex automotive and industrial parts. Second, high-quality sheet metal parts for automotive, household appliance, and general industrial applications. Third, checking fixtures for GD&T-oriented quality inspection of stamped components and assemblies. And fourth, custom welding jigs designed for accurate, repeatable production welding and assembly.

Automotive-Grade Quality and Certifications

In the automotive stamping industry, precision and consistency are non-negotiable. DIAN Stamping operates under a quality management system certified to ISO 9001 and follows IATF 16949-oriented manufacturing practices. The company has also earned recognition as a National High-Tech Enterprise and a Zhejiang Province Science and Technology SME, with TUV certification reinforcing its commitment to international quality standards.

The company processes a wide range of materials including high-strength steel (HSS), multiphase steel, aluminum alloys, stainless steel, and custom rolled and welded plate. Its stamping techniques cover progressive die stamping, transfer stamping, tandem stamping, deep drawing, and fine blanking — supported by secondary operations such as laser cutting, bending, welding, hemming, flanging, and powder coating.
