In the competitive world of automotive manufacturing, the quality of your tooling determines the quality of your production. Whether you are developing a new vehicle platform or scaling up production of existing components, finding a reliable partner for automotive stamping dies is critical to your success. LINHAI DIAN MOULD CO., LTD (Dian Stamping) has been serving the global automotive industry since 2003, offering end-to-end solutions from die design and fabrication to high-volume sheet metal stamping, welding assembly, and precision inspection.

A Factory with Real Scale and Real Capacity

Unlike many trading companies in the market, Dian Stamping is a true manufacturing facility. Situated in Huangyan, Taizhou, Zhejiang Province — a well-established industrial hub — the company operates a modern facility spanning approximately 50,000 m², with a dedicated die workshop of 4,000 m². A newly planned 35,000 m² facility featuring advanced press and coating lines is also underway, further expanding production capacity.

With around 110 employees, including 35 skilled die designers and technicians, Dian Stamping achieves an annual output of approximately 2,000 sets of medium and small stamping dies, with an annual die turnover of around RMB 50 million. This scale means the company can handle multiple projects simultaneously while maintaining consistent quality and on-time delivery.

Comprehensive Stamping Die Solutions

At the core of Dian Stamping's offering is its expertise in progressive die stamping — a high-efficiency process ideal for complex, high-volume parts. The company designs and manufactures a full range of die types, including:

• Progressive dies — for continuous, multi-stage stamping of complex geometries
• Transfer dies — for large and medium-sized parts requiring multiple forming operations
• Tandem / multi-station dies — for flexible, high-throughput production lines

Material capabilities are equally broad, covering multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel. This versatility allows Dian Stamping to serve a wide range of applications, from body-in-white structures and door systems to seating components, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis assemblies.

Beyond Dies: Sheet Metal Parts, Checking Fixtures & Welding Jigs

Dian Stamping is not just a die maker — it is a one-stop manufacturing partner. The company produces custom sheet metal parts for both automotive and household appliance industries, leveraging its stamping capabilities to deliver brackets, panels, hinges, structural components, and more. Secondary operations such as laser cutting, bending, welding, and powder coating are all available in-house.

Quality assurance is backed by precision checking fixture solutions. Dian Stamping designs and builds high-precision inspection fixtures that enable fast, repeatable dimensional verification of stamped parts — eliminating measurement errors and ensuring every component meets GD&T requirements. Complementing this, the company also offers custom welding jigs and fixtures for accurate, repeatable welding and assembly operations.

Proven Quality Systems and Customer Trust

Dian Stamping operates under an ISO 9001 quality management system, with manufacturing practices aligned to IATF 16949 automotive standards. The company's customer list includes major OEMs such as KIA, BYD, Toyota, Honda, Suzuki, and Geely, with exports reaching more than 10 countries worldwide. This track record demonstrates the company's ability to meet the rigorous quality, delivery, and cost requirements of global automotive supply chains.

Customization is a core strength. Dian Stamping can work from 2D drawings, 3D CAD data, or physical samples to develop tooling and parts tailored to your specifications. Prototype services are also available, allowing customers to validate designs before committing to full production. Typical lead times are 30–40 days for steel stamping dies and approximately 70 days for casting dies, depending on project complexity.
