Two Decades of Metal Forming Mastery

Founded in 2004, DIAN Stamping (台州迪昂冲压有限公司) has spent more than 20 years honing its craft in high-precision metal forming. Experience in this industry is not merely a number — it is a foundation built on thousands of successful projects, complex engineering challenges, and continuous process refinement. Our team has encountered virtually every scenario imaginable, from prototyping intricate multi-stage automotive components to executing high-volume production runs for household appliance manufacturers. This deep institutional knowledge allows us to anticipate potential manufacturing hurdles and develop robust solutions before they arise, saving our clients both time and cost.

Headquartered in Hongguang Industrial, Yanjiang, Linhai, Taizhou, Zhejiang Province, our facility is equipped with automated production lines, dedicated R&D laboratories, and integrated electrophoresis and powder coating lines. This vertical integration means every step of the production process — from die design to final finishing — is controlled in-house, ensuring consistent quality and faster turnaround times.

Comprehensive One-Stop Service Under One Roof

What truly sets DIAN Stamping apart is our ability to offer a true one-stop solution. Unlike many competitors who outsource portions of their production, we handle everything internally: mold design and development, sheet metal stamping, welding processing, powder coating, and finished product assembly. This full-industry-chain capability eliminates the coordination headaches, quality inconsistencies, and extended lead times that come with managing multiple vendors.

Our service portfolio covers four core areas:

1. Precision Stamping Dies & Progressive Dies

As a leading progressive die manufacturer, we design and build high-precision stamping dies, progressive dies, transfer dies, and tandem dies tailored to your specific application. Using advanced CAD/CAM design and precision machining, our tooling solutions deliver exceptional dimensional accuracy and repeatability — essential for high-volume production where consistency is king.

2. Custom Metal Stamped Parts

From prototyping to mass production, we manufacture automotive stamping parts and industrial components that meet the most stringent standards. Our material capabilities span multi-phase steel, aluminum, custom rolled steel, and stainless steel, allowing us to serve diverse industries including automotive, aerospace, electronics, and home appliances.

3. Welding Assembly Parts

We offer integrated welding assembly services using both robotic and manual techniques. Our capabilities cover sub-assemblies and complete assemblies, streamlining your production workflow and reducing supply chain complexity.

4. Checking Fixtures & Welding Jigs

Quality assurance is built into every stage of our process. As a trusted checking fixture manufacturer, we design and produce high-precision GD&T-compliant checking fixtures, inspection tooling, and welding jigs that ensure every part meets exact specifications. Our modular tooling systems enhance accuracy, repeatability, and efficiency in your production lines.

Global Certifications That Speak for Themselves

In industries where precision and reliability are non-negotiable, certifications are not just badges — they are promises. DIAN Stamping holds a suite of internationally recognized certifications that demonstrate our unwavering commitment to quality:

Our IATF 16949 certification is particularly significant for automotive clients, as it guarantees defect prevention, waste reduction, and consistent adherence to the rigorous quality standards demanded by global OEMs. Combined with our TUV certification, this provides independent verification of our product safety and quality.

Advanced Material Processing Capabilities

Different applications demand different materials, and DIAN Stamping has the expertise to work with a wide array of advanced metals:

• Multi-phase steel parts — High strength-to-weight ratio for structural automotive components
• Aluminum parts — Lightweight and corrosion-resistant for aerospace and modern vehicle applications
• Custom rolled steel and welded plate parts — For heavy-duty industrial and construction uses
• Stainless steel parts — Combining strength, hygiene, and aesthetic appeal for electronics and appliances

Our finishing capabilities include powder coating and electrophoresis, providing durable, corrosion-resistant surfaces that meet the highest industry standards.

Automotive Applications: Where Precision Meets Safety

The automotive industry remains our core focus, and our components can be found in critical systems across the vehicle:

• Seat Systems — Structurally sound stamped components ensuring safety and ergonomics
• Fuel Tank Systems — Complex stamped parts for secure fuel containment
