In the fast-paced world of automotive manufacturing, the quality of your tooling determines the quality of your product. Every door panel, chassis bracket, and body reinforcement starts with a precision-engineered die. As global automakers push for lighter, stronger, and more complex vehicle architectures, the demand for reliable automotive stamping dies has never been higher. Choosing the right partner — one that combines decades of hands-on experience with modern manufacturing capability — is essential to staying competitive.

Enter DIAN STAMPING (Linhai Dian Mould Co., Ltd.), a China-based manufacturer that has been designing and building precision stamping tooling since 2003. Headquartered in Huangyan, Taizhou, Zhejiang Province, the company has grown into a comprehensive one-stop manufacturing partner for automotive OEMs and Tier suppliers worldwide. From concept to production, DIAN STAMPING brings together die design, tryout, stamping, welding, and assembly under one roof.

A Manufacturing Powerhouse Built for Scale

DIAN STAMPING operates a modern facility covering approximately 50,000 m², including a dedicated die workshop of 4,000 m². With around 110 employees — including 35 skilled die designers and technicians — the company boasts an annual capacity of approximately 2,000 sets of medium and small stamping dies. Its annual die turnover is reported at approximately RMB 50 million, and a planned 35,000 m² expansion featuring new press lines and coating facilities is already underway.

Comprehensive Stamping Die Capabilities

As one of the experienced stamping die manufacturers in China, DIAN STAMPING offers a full range of tooling solutions tailored to the automotive industry. The company's die portfolio covers three primary types:

• Progressive Dies — High-efficiency multi-station dies for complex, high-volume parts. Ideal for producing consistent, tight-tolerance components with minimal handling.
• Transfer Dies — Designed for large and medium-sized parts that require multiple forming operations, with automatic part transfer between stations for optimal throughput.
• Tandem / Multi-Station Dies — Linked press lines for synchronized, high-output production of structural and body-in-white components.

The company also specializes in sheet metal stamping dies for a wide range of applications, including body-in-white panels, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis components. Materials processed include multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel.

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

DIAN STAMPING is not just a die maker — it is a full-service metal manufacturing partner. The company's sheet metal parts division produces custom automotive and household-appliance stampings, serving both OEM and aftermarket needs. Capabilities include progressive and transfer stamping, deep drawing, laser cutting, bending, welding, and assembly.

For quality assurance, DIAN STAMPING offers high-precision checking fixtures designed to GD&T standards, enabling fast and accurate dimensional verification of stamped components and assemblies. In addition, the company provides custom welding jigs for accurate, repeatable positioning during welding and assembly operations — ensuring that every part meets the exact specifications of the customer's design.

Quality Management and Certifications

DIAN STAMPING follows an ISO 9001-compliant quality management system and operates with IATF 16949-oriented automotive manufacturing practices. The company is a factory — not a trading company — which means customers benefit from direct quality control, transparent communication, and factory-direct pricing. Whether you need prototype runs or high-volume production, DIAN STAMPING can accommodate custom requirements from 2D drawings, 3D data, or physical samples.

Proven Track Record with Global OEMs

DIAN STAMPING's customer roster includes major automotive brands such as KIA, BYD, Toyota, Honda, Suzuki, and Geely. The company exports to more than 10 countries, serving global OEMs and Tier 1 suppliers who demand consistent quality, on-time delivery, and cost competitiveness. Typical delivery times are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity.
