A trusted partner with over 20 years of experience delivering precision stamping tooling, sheet metal parts, and inspection solutions to global automotive OEMs.

The global automotive industry continues to push for lighter, stronger, and more cost-effective vehicle structures. At the heart of this transformation lies a critical manufacturing process: metal stamping. Whether you are an OEM launching a new vehicle platform or a Tier-1 supplier scaling up production, the quality of your automotive stamping dies directly determines the dimensional accuracy, durability, and overall cost of your stamped components. Choosing the right partner for your tooling and production needs is one of the most consequential decisions you will make in your supply chain.

This is where LINHAI DIAN MOULD CO., LTD — better known as Dian Stamping Company — stands out. Since 2003, Dian Stamping has been serving global automotive brands from its modern manufacturing facility in Huangyan, Taizhou, Zhejiang Province, China. With over 20 years of hands-on experience, a 50,000 m² facility, and a dedicated team of 110 professionals — including 35 engineers and die designers — Dian Stamping delivers end-to-end solutions that cover tool design, die manufacturing, sheet metal stamping, welding assembly, and inspection fixturing.

A One-Stop Shop for Automotive Metal Forming

Unlike many suppliers that specialize in only one segment of the production chain, Dian Stamping offers a fully integrated service portfolio. This means you can source your tooling, production parts, inspection fixtures, and welding jigs from a single qualified partner — reducing coordination complexity, shortening lead times, and improving quality consistency.

Precision Tooling Backed by Real Capacity

At Dian Stamping, we understand that tooling quality is the foundation of production success. Our die workshop spans approximately 4,000 m² and is equipped with advanced machinery for manufacturing progressive stamping dies, transfer dies, and multi-station dies. With an annual capacity of approximately 2,000 sets of medium and small stamping dies and an annual die turnover of around RMB 50 million, we are well positioned to handle both prototype development and mass-production tooling programs.

Our material capabilities cover a wide spectrum: multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel. This versatility allows us to support diverse application areas — from body-in-white panels and door systems to seating components, instrument panel structures, fuel-tank systems, exhaust systems, and chassis parts.

We are also investing in the future. A planned 35,000 m² facility expansion will add new press lines and advanced coating capabilities, further strengthening our production capacity and quality control infrastructure.

Quality You Can Rely On

Dian Stamping operates under a quality management system that aligns with ISO 9001 standards and follows IATF 16949-oriented automotive manufacturing practices. Every die and stamped part undergoes rigorous inspection processes to ensure it meets the tight tolerances required by modern automotive engineering.

We are a factory-direct manufacturer — not a trading company. This means you benefit from factory pricing, direct communication with our engineering team, and full visibility into the production process. Whether you provide 2D drawings, 3D CAD data, or physical samples, we can develop a custom solution tailored to your specifications. Prototype services are also available to accelerate your product development cycles.

Global Reach, Local Expertise

Dian Stamping has built long-term partnerships with some of the world's most recognized automotive brands, including KIA, BYD, Toyota, Honda, Suzuki, and Geely. Our products are exported to more than 10 countries, serving OEMs and Tier suppliers across Asia, Europe, and the Americas.

Our customers return to us not only because of our competitive pricing and reliable quality, but also because of our commitment to partnership. We work closely with each client — from the initial tool design review through tryout, production, and ongoing support — to ensure that every project delivers on its performance and cost targets.

Beyond Dies: Complete Quality Assurance with Checking Fixtures and Welding Jigs

A key advantage of partnering with Dian Stamping is our ability to provide complementary tooling that ensures your production line runs smoothly. Our checking fixture solutions are designed for fast, reliable dimensional inspection of stamped parts — eliminating measurement variability and ensuring that every component meets your specifications before it moves to the next assembly stage. Similarly, our custom welding jigs and fixtures help you achieve consistent, repeatable weld quality in your assembly operations.

By integrating tooling, production, inspection, and welding support under one roof, Dian Stamping helps you reduce your supplier base, streamline communication, and bring your products to market faster.
