Two decades of precision engineering, vertically integrated manufacturing, and world-class quality systems

When automotive OEMs and Tier-1 suppliers search for a reliable stamping die manufacturer, they look beyond price alone. They need a partner with proven technical capability, rigorous quality certifications, and the production scale to deliver consistent results — order after order, year after year. DA Stamping (Dian Stamping), based in Taizhou, Zhejiang, China, has been that partner since 2004.

With a 50,000-square-meter production base, fully automated lines, and a comprehensive list of global certifications, DA Stamping has evolved from a local tool-and-die shop into a full-industry-chain service provider for the world's most demanding automotive brands — including KIA, BYD, Toyota, Honda, and Suzuki.

A Vertically Integrated Model That Delivers

What sets DA Stamping apart from many competitors is its vertically integrated, one-stop service model. Instead of outsourcing critical stages such as die design, welding, or surface finishing, the company manages everything in-house. This includes:

• Mold design, development, and manufacturing using advanced CAD/CAM systems
• Sheet metal stamping with high-precision presses
• Welding assembly and jig fabrication
• Electrophoresis and powder coating finishing
• Finished product assembly and quality inspection

This full-chain integration eliminates the quality risks, communication delays, and cost overruns that come with coordinating multiple vendors. It also means DA Stamping can offer free tooling and sampling during the development phase — a significant advantage for buyers evaluating new projects.

Automotive-Grade Quality Systems

In the automotive sector, component failure is not an option. That is why DA Stamping operates under internationally recognized quality management systems. The company holds IATF 16949 certification — the automotive industry's most stringent quality standard — along with ISO 9001 and TUV certification. It is also recognized as a National High-Tech Enterprise and a Zhejiang Provincial Technology-based SME, with its own High-tech Development Lab.

These certifications are not just wall decorations. They reflect disciplined processes in design control, supplier management, production monitoring, and continuous improvement — all of which directly impact the quality of automotive metal stamping parts delivered to customers.

Critical Applications Across the Vehicle

DA Stamping's components are found in some of the most safety-critical systems of a modern vehicle. The company supplies stamped parts and assemblies for:

• Seat Systems — structural brackets, rails, and adjustment mechanisms
• Fuel Tank Systems — mounting brackets, shields, and reinforcement plates
• Body-in-White Systems — structural panels and reinforcement members
• Exhaust Systems — heat shields, flanges, and hangers
• Door Systems — hinges, latches, and impact beams
• Clutch Systems — pressure plates and housings
• Dashboard Systems — cross-car beams and mounting brackets
• Chassis Systems — control arms, subframe components, and reinforcement parts

This breadth of application experience means that whether a buyer needs a progressive die for a high-volume chassis bracket or precision checking fixtures for dimensional validation of a new door panel, DA Stamping has the engineering depth to deliver.

Material Versatility and Technical Capability

Modern automotive engineering demands a wide range of materials, and DA Stamping has the equipment and expertise to process them all:

• Multi-phase steel parts — for high-strength structural applications
• Aluminum parts — for lightweight body and chassis components
• Stainless steel parts — for exhaust and corrosion-resistant assemblies
• Custom rolled steel and welded plate parts — for specialized structural needs

The company also supports non-standard OEM/ODM projects, making it a flexible partner for both prototyping and high-volume production runs.

Beyond Dies: A Complete Manufacturing Ecosystem

While DA Stamping is widely recognized as a stamping die manufacturer, its capabilities extend well beyond tooling. The company also manufactures precision checking fixtures and welding jigs that ensure dimensional accuracy and assembly consistency on the production line. Its powder coating line provides a durable, high-quality finish for sheet metal parts, eliminating the need for secondary suppliers.

This makes DA Stamping a true single-source solution for automotive suppliers who want to reduce supply chain complexity without compromising on quality.

Global Reach, Local Expertise

Headquartered in Hongguang Industrial, Yanjiang, Linhai, Taizhou, Zhejiang, DA Stamping is strategically located in one of China's most advanced manufacturing regions. The company exports to more than 10 countries and serves clients across Asia, Europe, and the Americas. Its affiliated companies — Linhai Diyao New Technology Co., Ltd. and Taizhou Elay International Trade Co., Ltd. — support its international operations and supply chain management.
