With 20+ years of experience, a 50,000 m² facility, and a track record serving KIA, BYD, Toyota, and Honda, DIAN STAMPING delivers precision tooling, stamped parts, and integrated assembly solutions — all under one roof.
When sourcing stamping die manufacturers, automotive OEMs and Tier-1 suppliers face a common challenge: finding a partner that combines precision engineering, production scale, and cost competitiveness without compromising quality. The global automotive industry demands tight tolerances, complex geometries, and consistent repeatability across millions of parts — and not every supplier can deliver on all fronts.
Enter DIAN STAMPING (Linhai Dian Mould Co., Ltd.), a vertically integrated manufacturer based in Taizhou, Zhejiang, China. Founded in 2003, the company has grown from a specialized tooling shop into a comprehensive automotive stamping dies and sheet metal fabrication partner, serving more than 10 countries and some of the world's best-known automotive brands.
Company Snapshot
Founded: 2003 | Location: Huangyan, Taizhou, Zhejiang | Facility: 50,000 m² | Employees: 110+ (35 die engineers) | Annual Die Capacity: 2,000+ sets | Key OEM Customers: KIA, BYD, Toyota, Honda, Suzuki, Geely
A Manufacturing Partner Built for Automotive Precision
What sets DIAN STAMPING apart from other stamping die manufacturers is its end-to-end vertical integration. Unlike many suppliers that specialize in only one segment of the production chain, DIAN STAMPING offers a complete manufacturing ecosystem that encompasses tool and die design, die manufacturing, sheet metal stamping, welding, assembly, and quality inspection — all within a single 50,000 m² campus.
The company's die workshop alone spans approximately 4,000 m², housing the equipment and expertise needed to produce progressive dies, transfer dies, and tandem/multi-station dies for large and medium-sized complex parts. With an annual output of roughly 2,000 sets of medium and small stamping dies and an annual die turnover of approximately RMB 50 million, DIAN STAMPING operates at a scale that rivals many established players in the industry.

Comprehensive Product and Service Portfolio
DIAN STAMPING's product offering spans four core categories, each designed to support different stages of the automotive manufacturing process:
- Stamping Dies — Precision progressive, transfer, and tandem dies for body-in-white components, door systems, seating systems, instrument panels, chassis systems, and more. The company processes multiphase steel, aluminum, custom rolled and welded plate, and stainless steel.
- Sheet Metal Parts — Custom stamped and fabricated metal parts for automotive and household appliance applications, including welding assemblies. From prototype to high-volume production, with options for laser cutting, bending, forming, and powder coating.
- Checking Fixtures — High-precision, GD&T-oriented inspection fixtures designed to verify dimensional accuracy of stamped components and welded assemblies. Essential for eliminating individual measurement variation in production quality control.
- Welding Jigs — Custom welding fixtures engineered for accurate, repeatable positioning during assembly operations. Supporting spot welding, TIG welding, and robotic welding processes.
The company also offers custom sheet metal parts fabrication services, accepting orders from 2D drawings, 3D data, or physical samples. Prototype services are available, and free metal samples can be provided with freight paid by the customer.
Quality Systems That Automotive OEMs Rely On
In the automotive industry, quality is non-negotiable. DIAN STAMPING operates under a quality management system that is ISO 9001 certified, with manufacturing practices aligned to IATF 16949 standards. This dual focus on certification and real-world process control ensures that every die, part, and fixture leaving the factory meets the rigorous expectations of global OEMs.
The company's quality assurance workflow includes in-line inspections during production, 3D scanning and CMM (Coordinate Measuring Machine) verification for dimensional accuracy, and functional testing of checking fixtures and welding jigs before shipment. This systematic approach minimizes defects and ensures that production lines at customer sites run smoothly from the first stamping cycle.
Proven OEM Partnerships Across the Globe
One of the strongest indicators of a stamping die manufacturer's capability is the caliber of its customers. DIAN STAMPING's client roster includes KIA, BYD, Toyota, Honda, Suzuki, and Geely — names that demand nothing less than precision, reliability, and on-time delivery. These long-term partnerships, built over more than two decades, demonstrate the company's ability to meet the technical and commercial requirements of both traditional internal combustion engine vehicle platforms and new energy vehicle programs.
With exports reaching more than 10 countries, DIAN STAMPING has established itself as a globally recognized supplier of automotive tooling and stamped components. The company's factory-direct pricing model — eliminating intermediary markups — offers customers a cost advantage of 20-30% compared to many Western suppliers, without sacrificing quality or lead time.
Fast Lead Times and Scalable Production
DIAN STAMPING understands that time-to-market is critical in the automotive industry. Typical delivery timelines are 30-40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity and material requirements. The company's 110-strong workforce, including 35 experienced die designers and technicians, works across multiple shifts to maintain these lead times while handling concurrent projects.
Looking ahead, DIAN STAMPING is investing in a new 35,000 m² facility featuring state-of-the-art press lines and coating systems. This expansion will significantly increase production capacity and enable the company to take on larger, more complex programs for its growing global customer base.
Application Areas Across the Vehicle
DIAN STAMPING's tooling and stamped parts are used across a wide range of automotive applications:
Body-in-White: Side frames, rear outer panels, spare tire wells, A-pillar inner panels, and B-pillar assemblies.
Door Systems: Hinge reinforcement plates, water-cut reinforcement panels, guides, and middle gates.
Seating Systems: Seat basins, support beams, battery cases, chassis seats, and various beams and frames.
Instrument Panels, Exhaust Systems, and Chassis: Heat shields, floor panels, cross members, swing arms, and control arm assemblies.

Why DIAN STAMPING Stands Out Among Stamping Die Manufacturers
In a competitive landscape, DIAN STAMPING differentiates itself through several key attributes:
True vertical integration — From die design and fabrication to stamping, welding, inspection, and assembly, the company controls every step of the manufacturing process, ensuring consistency, traceability, and faster turnaround times.
Multi-material processing expertise — The ability to work with multiphase steel, aluminum alloys, stainless steel, and custom rolled and welded plate gives design engineers greater flexibility in material selection.
Factory-direct economics — As a manufacturing facility rather than a trading company, DIAN STAMPING offers competitive pricing without compromising on quality or service.
Proven global track record — Long-standing relationships with major automotive OEMs across multiple countries provide tangible evidence of the company's reliability and technical capability.
