When sourcing critical tooling and stamped components for vehicle production, automotive OEMs and Tier-1 suppliers face a common challenge: finding a manufacturing partner that delivers both precision engineering and cost-effective scalability. DIAN STAMPING, a China-based stamping die manufacturers with over two decades of experience, has built its reputation by bridging exactly that gap. Headquartered in Linhai, Taizhou, Zhejiang Province, the company has grown from a local die shop in 2003 into a comprehensive one-stop manufacturing partner serving global automotive brands including KIA, BYD, Toyota, Honda, Suzuki, and Geely, with exports reaching more than 10 countries.

A Manufacturing Facility Built for Scale and Precision

DIAN STAMPING operates a modern facility spanning approximately 50,000 m², with a dedicated die workshop of 4,000 m². The company's manufacturing capabilities are supported by a team of around 110 employees, including approximately 35 experienced die designers and technicians. With an annual capacity of about 2,000 sets of medium and small stamping dies and a reported annual die turnover of approximately RMB 50 million, DIAN STAMPING has the production scale to support both prototype development and high-volume production runs.

A planned 35,000 m² expansion facility featuring new press lines and advanced coating capabilities will further strengthen the company's manufacturing capacity, enabling it to serve an even broader range of customer requirements.

Comprehensive Product Portfolio Across the Automotive Value Chain

Unlike many specialized tooling shops, DIAN STAMPING offers a fully integrated suite of products and services that covers the entire production cycle — from die design and fabrication to finished stamped parts and quality inspection tooling. The company's product lineup is organized into four core categories:

1. Stamping Dies — The Core of Precision Tooling

DIAN STAMPING specializes in automotive stamping dies, including progressive dies, transfer dies, and tandem/multi-station dies for large and medium-sized complex parts. These dies are designed and manufactured for applications spanning body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems. The company's die-making capabilities cover a wide range of materials including multiphase steel, aluminum, custom rolled and welded plate, and stainless steel, enabling customers to meet diverse design and performance requirements.

2. Sheet Metal Parts — From Prototype to Production

Beyond die manufacturing, DIAN STAMPING produces high-quality stamped custom sheet metal parts for both automotive and household-appliance applications. The company offers sheet-metal fabrication, welding assemblies, laser cutting, and secondary operations such as deburring, bending, and coating. Whether customers need prototype parts for validation or high-volume production components, DIAN STAMPING delivers consistent quality with competitive lead times.

3. Checking Fixtures — Precision Quality Assurance

DIAN STAMPING also manufactures high-precision checking fixture solutions for GD&T-oriented inspection of stamped components and welded assemblies. These fixtures enable rapid, repeatable quality checks of complex geometries that would be difficult or time-consuming to measure with conventional tools. As the company notes, press dies and checking fixtures go hand in hand — and eliminating measurement variability is essential for consistent production quality.

4. Welding Jigs — Accurate Assembly, Every Time

Rounding out the product portfolio, DIAN STAMPING provides custom welding jig solutions for accurate, repeatable positioning and welding of automotive and industrial assemblies. These fixtures are designed to support both manual and automated welding processes, ensuring consistent weld quality and dimensional accuracy across production runs.

Quality Systems and Certification

DIAN STAMPING operates under an ISO 9001 quality management system and follows IATF 16949-oriented automotive manufacturing and quality practices. The company positions itself as a factory-direct manufacturer — not a trading company — which means customers benefit from direct communication with the production team, greater quality control transparency, and more competitive pricing.

Customization is available from 2D drawings, 3D data, or physical samples, and prototype services are offered to support new product development programs. Free metal samples are available upon request, with freight paid by the customer.

Global Customer Base and Delivery Capability

DIAN STAMPING's customer roster includes some of the world's most recognizable automotive brands:

With exports to more than 10 countries, the company has established logistics and communication processes that support international customers. Typical delivery is 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity and specifications.
