Two Decades of Precision: The Dian Stamping Story

Founded in 2003 in Huangyan, Taizhou, Zhejiang Province -- the heart of China's mould-making industry -- Dian Stamping has grown from a focused die workshop into a full-spectrum manufacturing partner. Today, the company employs approximately 110 people, including 35 experienced die designers, and operates out of a 50,000-square-meter facility with a dedicated 4,000-square-meter die workshop.

The company's annual capacity reaches roughly 2,000 sets of medium and small stamping dies, with an annual die turnover of approximately RMB 50 million. A new 35,000-square-meter facility is already on the horizon, complete with new press lines and coating capabilities -- a clear signal that Dian Stamping is investing for the next two decades of growth.

What sets Dian Stamping apart from traditional stamping die manufacturers is its commitment to vertical integration. From die design and development to sheet metal stamping, welding, powder coating, and finished product assembly, every step happens in-house -- no outsourcing, no handoffs, no surprises.

Comprehensive Capabilities Under One Roof

Dian Stamping offers a complete product ecosystem that covers the full lifecycle of a stamped part:

Stamping Dies

The company specializes in progressive die stamping, transfer dies, and tandem dies for medium to large precision complex parts. Advanced CAD/CAM tools -- including Cimatron -- enable engineers to design and simulate tooling before any steel is cut, reducing lead times and eliminating costly rework. Dies are available in both steel (30-40 days delivery) and casting (~70 days delivery) depending on volume and complexity requirements.

Sheet Metal Parts

As a full-service metal stamping parts manufacturer, Dian Stamping handles custom fabrication from prototype through high-volume production. The company works with a wide range of materials including multiphase steel, aluminum alloys, custom rolled steel, welded plate, and stainless steel.

Checking Fixtures & Welding Jigs

To close the loop on quality assurance, Dian Stamping designs and builds precision checking fixtures (GD&T-compliant) and custom welding jigs -- ensuring that every part meets dimensional specifications before it reaches the assembly line.

The OEM Advantage: Proven by Global Brands

Few things matter more in automotive stamping than a proven track record. Dian Stamping's customer roster includes some of the world's most demanding automakers: KIA, BYD, Toyota, Honda, Suzuki, and Geely. These OEMs rely on Dian Stamping for dies and parts that go into critical vehicle systems -- body-in-white structures, door systems, seating systems, instrument panels, fuel tanks, exhaust systems, clutches, and chassis components.

Quality management follows IATF 16949-oriented practices alongside ISO 9001 certification. The company is also recognized as a National High-Tech Enterprise, reflecting its ongoing investment in R&D and process innovation. For customers, this translates into consistent dimensional accuracy, reliable lead times, and the kind of disciplined quality documentation that automotive auditing demands.

Whether it is a progressive die running millions of parts per year or a transfer die for a complex chassis bracket, the quality framework stays the same: traceable materials, validated processes, and real force-signal monitoring during production.

Materials, Applications, and Engineering Flexibility

Modern automotive design demands materials that are stronger, lighter, and more formable than ever. Dian Stamping has built deep expertise across a broad material spectrum:

• Multiphase steel (high-strength)
• Aluminum alloys
• Custom rolled steel plate
• Welded plate assemblies
• Stainless steel

This material versatility is matched by application breadth. Dian Stamping's parts and tooling serve eight major automotive subsystems. From fuel tank shields and seat rails to door inner panels and exhaust hangers, the company has the engineering depth to handle diverse geometries, tolerances, and surface finish requirements.

Customization is a core strength. Customers can submit parts for quotation in any format -- 2D drawings, 3D CAD data, or physical samples -- and Dian Stamping's engineering team will develop the tooling concept, simulate the forming process, and deliver production-ready dies with full documentation.

Global Reach, Factory-Direct Value

Dian Stamping exports to more than 10 countries across Asia, Europe, and the Americas. Despite its global footprint, the company operates as a direct manufacturer -- not a trading company. This means customers get factory-direct pricing without intermediary markups, while maintaining direct communication with the engineers and production teams who actually build their tooling.

Lead times are competitive: 30 to 40 days for steel dies and approximately 70 days for casting dies, depending on complexity. The upcoming 35,000-square-meter facility expansion will add new press capacity and in-house coating lines, further reducing turnaround times and increasing production flexibility.

For OEMs and tier suppliers looking to consolidate their supply base, Dian Stamping offers a compelling value proposition: one partner, one quality system, one production floor -- from the first die design to the last assembled part.
