When global automotive OEMs need reliable tooling and high-volume stamped components, they look for a partner who combines engineering depth with manufacturing scale. Dian Stamping — the manufacturing division of LINHAI DIAN MOULD CO., LTD — has been providing exactly that since 2003, serving brands like KIA, BYD, Toyota, Honda, Suzuki, and Geely from its 50,000 m² facility in Zhejiang, China.

A Manufacturing Partner, Not Just a Supplier

With over two decades of industry experience, Dian Stamping has built a reputation as one of the leading stamping die manufacturers in China. The company operates a modern 50,000 m² facility that houses a dedicated die workshop of approximately 4,000 m², staffed by around 110 employees including 35 die designers and technicians. This scale allows the company to produce approximately 2,000 sets of medium and small stamping dies annually, with an annual die turnover of approximately RMB 50 million.

Unlike many trading companies in the market, Dian Stamping is a factory-first operation. The company emphasizes direct manufacturing control, which translates into competitive pricing, shorter lead times, and consistent quality across every project.

Comprehensive Capabilities in Automotive Stamping Dies

Dian Stamping's core strength lies in its ability to design and manufacture a wide range of automotive stamping dies. The company's die engineering team is proficient in progressive dies, transfer dies, and tandem/multi-station dies, covering everything from body-in-white components to structural parts for door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems.

The company processes a diverse range of materials including multiphase steel, aluminum, custom rolled and welded plate, and stainless steel. This material versatility is critical for modern automotive lightweighting and crash-performance requirements. Typical delivery for steel stamping dies is 30–40 days, while casting stamping dies are delivered in approximately 70 days, depending on project complexity.

Beyond Dies: A One-Stop Solution

What sets Dian Stamping apart from many progressive die stamping providers is its truly integrated service offering. The company delivers end-to-end solutions that go beyond tooling:

• Sheet Metal Parts — High-volume stamping production, sheet-metal fabrication, custom metal parts, and welded assemblies for automotive and household appliance applications.
• Checking Fixture — High-precision, GD&T-oriented inspection fixtures that ensure every stamped component meets dimensional specifications before it moves to assembly.
• Welding Jig — Custom welding fixtures designed for accurate, repeatable positioning during welding and assembly operations.
• Welding Parts and Assembly — Complete welding and assembly services to deliver finished sub-assemblies ready for vehicle integration.

This one-stop approach eliminates the coordination overhead of managing multiple suppliers, reduces total cost, and accelerates time-to-market for new vehicle programs.

Quality Built Into Every Process

Dian Stamping operates under an ISO 9001 quality management system and follows IATF 16949-oriented automotive manufacturing practices. Every die, part, and fixture undergoes rigorous inspection throughout the production process. The company's checking fixture capabilities — including custom gauge check fixtures and bend check fixtures — are designed to eliminate measurement variability and ensure that every part meets the tight tolerances required by modern automotive engineering.

Customers can submit requirements in the form of 2D drawings, 3D CAD data, or physical samples. The engineering team then develops optimized die designs using industry-standard software, ensuring that the final tooling delivers consistent performance across high-volume production runs.

Global Reach with Local Expertise

Dian Stamping exports to more than 10 countries and counts some of the world's best-known automotive brands among its customer base. The company's location in Huangyan, Taizhou — a well-established manufacturing hub in Zhejiang Province — provides access to a mature supply chain ecosystem, skilled labor, and efficient logistics networks.

A planned new 35,000 m² facility featuring advanced press lines and coating lines will further expand the company's capacity and capabilities, positioning Dian Stamping to meet the growing demand for precision-stamped components in the electric vehicle and new energy vehicle sectors.
