In the competitive landscape of automotive manufacturing, the quality of stamped components depends heavily on the precision of the tooling that produces them. Finding a partner that can deliver not only high-performance stamping dies but also reliable stamped parts, inspection fixtures, and welding tooling under one roof is a significant strategic advantage. DIAN STAMPING, operating under LINHAI DIAN MOULD CO., LTD., has positioned itself as exactly that kind of one-stop partner for global automotive OEMs and Tier suppliers.

Over Two Decades of Stamping Die Expertise

Founded in 2003 in Taizhou, Zhejiang Province, DIAN STAMPING brings more than 20 years of hands-on experience in the tool and die industry. With a modern facility spanning approximately 50,000 square meters and a dedicated die workshop of 4,000 square meters, the company has the infrastructure to handle complex, high-volume projects. The team of around 110 employees includes approximately 35 die designers and technicians, ensuring that every project receives expert engineering attention from concept through production.

The company's annual capacity of approximately 2,000 sets of medium and small stamping dies, combined with a reported annual die turnover of around RMB 50 million, speaks to its established position in the market. A planned 35,000-square-meter expansion featuring new press and coating lines will further strengthen its capabilities.

Comprehensive Progressive Die Stamping Solutions

At the core of DIAN STAMPING's offering is its expertise in progressive die stamping. The company designs and manufactures progressive dies, transfer dies, and tandem/multi-station dies for a wide range of automotive and industrial applications. These precision tools are engineered to produce complex geometries with tight tolerances at high production speeds, making them ideal for high-volume manufacturing environments.

The company's stamping dies cover critical automotive systems including body-in-white, door systems, seating systems, instrument panels, fuel tank systems, exhaust systems, clutch systems, and chassis systems. Material processing capabilities extend to multiphase steel, aluminum alloys, custom rolled steel, welded plate, and stainless steel, providing flexibility for diverse project requirements.

Precision Metal Stamping Dies for Automotive Applications

DIAN STAMPING's metal stamping dies are designed and manufactured using advanced CAD/CAM software, precision machining equipment, and rigorous testing protocols. Whether the requirement is for progressive tooling in high-speed stamping presses or transfer dies for large, complex panels, the company delivers tooling solutions that maximize uptime, reduce scrap, and ensure consistent part quality.

The company's in-house capabilities include full die design, development, manufacturing, tryout, and modification. This vertically integrated approach means faster turnaround times, better quality control, and more competitive pricing compared to suppliers that outsource parts of the process.

One-Stop Service Beyond Tooling

What truly sets DIAN STAMPING apart is its ability to serve as a complete manufacturing partner. Beyond tooling, the company offers four integrated service lines:
