Precision Metal Stamping Dies & Custom Sheet Metal Parts: Why DIAN STAMPING Is Your Trusted Partner for Automotive Manufacturing

A deep dive into one-stop, high-precision stamping solutions from a certified National High-Tech Enterprise in China

The global automotive industry is evolving at an unprecedented pace. Lightweight materials, tighter safety regulations, and the shift toward electric vehicles are placing new demands on every link of the supply chain - especially in metal forming and tooling. For OEMs and Tier-1 suppliers seeking a reliable partner, the choice of progressive die stamping and precision tooling is no longer just about cost; it is about consistency, lead time, and end-to-end capability.

Enter DIAN STAMPING (LINHAI DIAN MOULD CO., LTD), a manufacturer with over 20 years of industry experience and a comprehensive portfolio spanning stamping dies, sheet metal parts, checking fixtures, and welding jigs. Headquartered in Linhai, Taizhou, Zhejiang Province - a major manufacturing hub in China - the company has grown from a modest tooling workshop into a 50,000-square-meter production facility serving global automotive brands including KIA, BYD, Toyota, Honda, Suzuki, and Geely, with exports to more than 10 countries.

A One-Stop, Full-Industry-Chain Capability

What sets DIAN STAMPING apart is its vertically integrated service model. Unlike many suppliers that specialize in only one segment of the stamping process, DIAN STAMPING offers a true one-stop solution: from mold design and development, to sheet metal stamping, welding processing, powder coating, and finished product assembly. This integrated approach eliminates the coordination overhead and quality risks that come with managing multiple subcontractors.

DIAN STAMPING's core service categories:

  • Stamping Dies - Progressive dies, transfer dies, and tandem dies for large and medium-sized complex parts, designed using advanced CAD/CAM software.
  • Sheet Metal Parts - Custom sheet metal parts for automotive body panels, structural components, brackets, and household appliance parts.
  • Checking Fixtures - High-precision GD&T-oriented inspection fixtures that ensure dimensional accuracy and eliminate measurement variability.
  • Welding Jigs - Custom welding fixtures and modular tooling systems for accurate, repeatable assembly and production.

Precision Tooling for High-Performance Stamping

At the heart of DIAN STAMPING's offering is its automotive stamping dies capability. The company operates a dedicated die workshop of approximately 4,000 square meters, staffed by around 35 experienced die designers and technicians. With an annual capacity of about 2,000 sets of medium and small stamping dies and an annual die turnover of approximately RMB 50 million, DIAN STAMPING is well-equipped to handle both prototype development and high-volume production runs.

The company's die design and manufacturing process covers the full spectrum: progressive dies for high-speed, multi-station stamping; transfer dies for large, complex panels; and tandem dies for multi-operation forming. All tooling is engineered with tight tolerances to ensure consistent part quality across thousands of production cycles. The team uses professional CAD/CAM platforms and conducts rigorous tryout testing before delivery, minimizing the risk of issues during production.
