When you are sourcing tooling for a new vehicle program or a high-volume stamped component, the automotive stamping dies you choose determine your downstream efficiency, dimensional accuracy, and overall cost per part. Not every die shop can deliver the combination of engineering depth, manufacturing scale, and quality discipline that automotive OEMs and Tier 1 suppliers require. This is where LINHAI DIAN MOULD CO., LTD (Dian Stamping) stands apart — a vertically integrated manufacturer with over two decades of dedicated service to the automotive industry.

Founded in 2003 in Huangyan, Taizhou, Zhejiang Province, Dian Stamping has grown from a specialized die shop into a full-spectrum metal forming partner. The company's 20+ years of continuous operation in the automotive supply chain means its engineering and production teams have encountered — and solved — the full range of challenges that come with body-in-white, chassis, seating, and powertrain components.

The company's client list reads like a who's who of global automotive: KIA, BYD, Toyota, Honda, Suzuki, and Geely. With exports reaching more than 10 countries, Dian Stamping combines Chinese manufacturing efficiency with international quality standards.

Scale matters in automotive tooling. Dian Stamping operates a modern facility covering approximately 50,000 m², with a dedicated die workshop of 4,000 m². A planned new 35,000 m² facility will add even more press and coating capacity.

The annual die turnover of approximately RMB 50 million reflects a steady, high-volume operation that major automakers trust for their production tooling needs.

Dian Stamping covers the entire spectrum of metal forming tooling. Whether your project calls for progressive die stamping for high-speed, multi-operation production, transfer dies for complex medium-to-large parts, or tandem dies for structural body components with high-tensile materials, the company has the engineering and machining resources to deliver.

The design team works with AutoCAD, SolidWorks, and CATIA, ensuring seamless integration with your existing product development workflow. Prototype services are available from 2D drawings, 3D data, or physical samples.

One of the strongest advantages Dian Stamping offers is its ability to deliver not just tooling, but the full production chain. The company produces high-precision stamped sheet metal parts, checking fixture solutions for GD&T-compliant dimensional verification, custom welding jigs, and welded assemblies. This means you can source your dies, production stamping, inspection fixtures, and welding fixtures from a single supplier — reducing lead time, simplifying communication, and cutting overall project cost.

Material capabilities include multiphase steel, aluminum, custom rolled and welded plate, and stainless steel. In-house secondary operations such as laser cutting, bending, welding, and powder coating eliminate the need for multiple subcontractors.

Automotive suppliers operate under some of the most demanding quality standards in manufacturing. Dian Stamping's quality management system is ISO 9001 certified, and the company follows IATF 16949-oriented practices throughout its tooling and production processes. Every die, stamped part, and checking fixture undergoes rigorous dimensional verification before leaving the factory.

Typical delivery timelines are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity. The company's factory-direct model means you get competitive pricing without the markup of a trading intermediary.

Dian Stamping's tooling and stamped components are used across a wide range of automotive systems:

This breadth of application experience means Dian Stamping understands the functional and safety requirements that different vehicle subsystems demand.

In a market where custom metal stamping dies are available from dozens of suppliers, Dian Stamping differentiates itself through four key advantages:
