When sourcing automotive stamping dies and stamped metal components, automotive OEMs and Tier 1 suppliers face a familiar challenge: how do you find a partner who can deliver precision tooling, high-volume production, and downstream services under one roof — without sacrificing quality or cost control?
Many manufacturers specialise in one segment: they build dies, or they stamp parts, or they make checking fixtures. But few can integrate all four — die making, sheet metal stamping, inspection fixturing, and welding/assembly — into a seamless, end-to-end production flow. That is exactly the gap that DIAN STAMPING (LINHAI DIAN MOULD CO., LTD) was built to fill.
Company Snapshot: Established in 2003 in Huangyan, Taizhou, Zhejiang Province, DIAN STAMPING operates a 50,000 m² modern facility with a dedicated 4,000 m² die workshop. The company employs approximately 110 people, including 35 die designers and technicians, and produces roughly 2,000 sets of medium and small stamping dies annually, with an annual die turnover of approximately RMB 50 million.
A Full-Service Model That Reduces Supply Chain Complexity
DIAN STAMPING's vertically integrated model covers the entire product lifecycle:
- Precision Tooling: Progressive dies, transfer dies, and tandem/multi-station dies for large and medium-sized complex parts.
- Sheet Metal Stamping: High-volume production of automotive body, chassis, seating, and structural components.
- Checking Fixtures: GD&T-oriented inspection fixtures that eliminate individual measurement variation and ensure every part meets print specifications.
- Welding Jigs and Assembly: Custom fixtures and welding services for repeatable, high-accuracy assembly.
This one-stop approach means OEMs can consolidate their supplier base, reduce logistics overhead, and shorten time-to-market — all while maintaining a single point of accountability for quality and delivery.
Deep Automotive Expertise Across Multiple Vehicle Systems
Unlike general-purpose stamping die manufacturers, DIAN STAMPING has built its reputation on deep automotive domain knowledge. The company's tooling and stamped parts are used across a wide range of vehicle systems:
- Body-in-White: A-pillar panels, side frames, floor panels, and reinforcement structures.
- Door Systems: Hinge reinforcements, inner/outer panels, and water-cut reinforcement panels.
- Seating Systems: Seat basins, support beams, and B-pillar components.
- Instrument Panels and Chassis: Dashboard crossmembers, chassis seats, and control arms.
- Powertrain and Exhaust: Heat shields, fuel-tank components, and clutch system parts.
DIAN has served OEM customers including KIA, BYD, Toyota, Honda, Suzuki, and Geely, and exports to more than 10 countries worldwide. This breadth of experience gives the company a practical understanding of diverse quality standards, material specifications, and production requirements across global automotive markets.
Advanced Material Processing Capabilities
Modern automotive design increasingly demands lightweight materials and high-strength grades. DIAN STAMPING has invested in the capability to process a wide spectrum of materials, including:
- Multiphase steel (AHSS / UHSS) for structural crash-management components
- Aluminum alloys for lightweight body panels and EV chassis components
- Custom rolled and welded plate for complex structural assemblies
- Stainless steel for corrosion-resistant exhaust and heat-shield applications
Combined with progressive die stamping and transfer die techniques, the company can produce complex geometries with tight tolerances while maintaining the cost efficiency required for high-volume production runs.
Quality Assurance Rooted in Automotive Standards
DIAN STAMPING operates under a quality management system certified to ISO 9001, and follows IATF 16949-oriented practices throughout its manufacturing and inspection processes. The company's checking fixture capabilities — including custom-designed inspection tools for stamped components and welded assemblies — ensure that every part can be verified against print dimensions quickly and reliably. This is especially critical for production sites where press dies and checking fixtures must work as a matched set to eliminate measurement inconsistency.
Factory-Direct Pricing with Flexible Customization
As a factory rather than a trading company, DIAN STAMPING offers direct pricing without intermediary markups. Customers can submit requirements via 2D drawings, 3D data, or physical samples for custom tooling and production. Prototype services are available for new program development, and free metal samples can be provided (with freight paid by the customer) to validate quality before committing to full-scale production.
Typical lead times are 30–40 days for steel stamping dies and approximately 70 days for casting dies, with project-specific adjustments to meet urgent program schedules.
Planned Expansion for Growing Global Demand
DIAN STAMPING is currently developing a new 35,000 m² facility featuring advanced press lines and coating capabilities. This expansion will significantly increase production capacity and enable the company to take on larger, more complex programs while maintaining the delivery reliability that global OEMs demand.
