In the fast-evolving automotive industry, the quality of every stamped component starts with the die. Choosing the right automotive stamping dies manufacturer is not just about tooling — it is about ensuring dimensional accuracy, production efficiency, and long-term supply reliability for vehicle programs that span years.

LINHAI DIAN MOULD CO., LTD (DIAN STAMPING) has been a dedicated provider of precision stamping tooling and metal-formed parts since 2003. Headquartered in Huangyan, Taizhou, Zhejiang Province — one of China's most established manufacturing hubs — the company brings over two decades of hands-on experience in designing and building high-performance dies for automotive OEMs and Tier 1 suppliers across the globe.

A Manufacturing Scale Built for Automotive Programs

DIAN STAMPING operates a modern facility covering approximately 50,000 m², including a dedicated die workshop of 4,000 m². With a team of around 110 employees — among them roughly 35 experienced die designers and technicians — the company has an annual capacity of about 2,000 sets of medium and small stamping dies, with an annual die turnover of approximately RMB 50 million.

To meet growing demand, a new 35,000 m² facility featuring advanced press and coating lines is underway, further expanding DIAN's production capabilities. As one of the leading stamping die manufacturers in China, the company is well-positioned to support both ongoing production programs and new vehicle launches.

Comprehensive Product Portfolio

DIAN STAMPING offers a one-stop solution covering the full spectrum of tooling and metal parts, from initial die design to serial production of stamped components, inspection fixtures, and welding assemblies.

A checking fixture is a critical quality tool that quickly confirms whether a manufactured workpiece meets the specified dimensions, eliminating measurement variability and speeding up inspection. DIAN's checking fixtures are designed in parallel with press dies, ensuring seamless dimensional verification throughout the production cycle.

Proven Track Record with Global OEMs

Experience matters in automotive tooling. DIAN STAMPING has served major automotive brands including KIA, BYD, Toyota, Honda, Suzuki, and Geely, and exports its tooling and parts to more than 10 countries. This track record demonstrates the company's ability to meet the stringent quality, delivery, and engineering standards that global OEMs demand.

Application areas span body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems — covering virtually every structural and interior metal component category in a modern vehicle.

Quality Management and Industry Standards

DIAN STAMPING operates under a quality-management system certified to ISO 9001, and follows IATF 16949-oriented automotive manufacturing and quality practices. As a factory-direct manufacturer — not a trading company — the company maintains full control over every stage of production, from raw material sourcing and die design to tryout, inspection, and final delivery.

Typical delivery times are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity. Free metal samples are available upon request, with freight paid by the customer.

Customization and Engineering Support

DIAN STAMPING accepts custom orders based on 2D drawings, 3D data, or physical samples. Prototype services are also available, allowing customers to validate designs before committing to full production tooling. The company's engineering team works closely with clients throughout the development cycle, providing design-for-manufacturing feedback and process optimization.

Capabilities include processing of multiphase steel, aluminum, custom rolled and welded plate, and stainless steel, using progressive die, transfer die, and tandem/multi-station die technologies. Secondary operations such as laser trimming, hemming, flanging, and spot welding are also available for assembly-ready components.
