In the competitive world of automotive manufacturing, the quality of your tooling directly determines the quality of your final product. Choosing the right partner for precision dies and stamped components is not just a procurement decision — it is a strategic one that impacts cost, lead time, and vehicle performance.
A Legacy of Precision Since 2003
Founded in 2003 and headquartered in Huangyan, Taizhou, Zhejiang Province, LINHAI DIAN MOULD CO., LTD (DIAN STAMPING) has spent over two decades perfecting the art of metal forming. What began as a specialized tool and die workshop has grown into a comprehensive manufacturing facility spanning approximately 50,000 m², with a dedicated die workshop of 4,000 m² and a team of around 110 skilled professionals, including 35 die designers and technicians.
Today, DIAN STAMPING stands among the most reliable stamping die manufacturers serving the global automotive industry, with an annual capacity of approximately 2,000 sets of medium and small stamping dies and an annual die turnover of approximately RMB 50 million.
Comprehensive Die Manufacturing Capabilities
DIAN STAMPING specializes in a full spectrum of stamping die technologies designed to meet the demanding requirements of modern automotive production. The company's core die offerings include:
Progressive Dies — Ideal for high-volume production of complex parts with multiple operations performed in a single press stroke. Progressive dies at DIAN STAMPING are engineered for consistent dimensional accuracy across long production runs, making them the preferred choice for body-in-white components and structural reinforcements.
Transfer Dies — Designed for large and medium-sized parts requiring deep drawing and complex forming sequences. Transfer die technology allows DIAN STAMPING to produce components with intricate geometries that single-station dies cannot achieve.
Tandem / Multi-Station Dies — Offering flexibility for medium-volume production with quick changeover capabilities, these dies enable efficient production of multiple part variants on the same press line.
Whether you need progressive die stamping for high-volume runs or custom tooling for specialized applications, DIAN STAMPING delivers precision-engineered solutions that maximize throughput while minimizing waste.
Material Expertise Across the Full Spectrum
Modern automotive engineering demands versatility in material processing. DIAN STAMPING's manufacturing team is proficient in working with a wide range of materials, including:
• Multiphase and Advanced High-Strength Steel (AHSS) — For lightweight body structures with superior crash performance
• Aluminum Alloys — Supporting the automotive industry's shift toward vehicle weight reduction
• Custom Rolled and Welded Plate — For specialized structural and chassis components
• Stainless Steel — For exhaust systems, heat shields, and corrosion-resistant applications
This material versatility, combined with deep process knowledge, ensures that every automotive stamping dies project is executed with the optimal material-die interface for maximum tool life and part quality.
Quality Assurance Built on Global Standards
Quality at DIAN STAMPING is not an afterthought — it is embedded in every stage of the manufacturing process. The company operates under an ISO 9001-certified quality management system, with practices aligned to IATF 16949 automotive standards. This commitment to quality is reinforced by a dedicated inspection infrastructure that includes:
• Checking Fixtures — Precision GD&T-based inspection tools that verify dimensional accuracy of stamped components and assemblies, eliminating individual measurement variation
• In-Process Quality Control — Real-time monitoring during stamping operations to detect deviations before they become defects
• Final Inspection & Documentation — Comprehensive reporting packages that meet OEM quality submission requirements
DIAN STAMPING's checking fixtures are designed and manufactured in-house, ensuring seamless integration between die design, part production, and quality verification. This integrated approach significantly reduces the time from first article to production approval.
Beyond Dies: A One-Stop Manufacturing Partner
What sets DIAN STAMPING apart from conventional tooling suppliers is its ability to deliver end-to-end manufacturing solutions. Beyond precision stamping dies, the company offers:
• Sheet Metal Parts Production — High-volume stamping of automotive body panels, structural components, brackets, and assemblies
• Welding Jigs and Fixtures — Custom-designed positioning tools that ensure repeatable, accurate welding for sub-assemblies and full assemblies
• Welding and Assembly Services — From MIG/TIG welding to spot welding, with full assembly line capabilities
• Prototype to Production — Fast-turnaround prototyping services that accelerate new vehicle program timelines
Application areas span body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems — covering virtually every stamped metal component in a modern vehicle.
A Track Record Trusted by Global OEMs
DIAN STAMPING's customer roster speaks to its manufacturing excellence. The company serves renowned automotive OEMs including KIA, BYD, Toyota, Honda, Suzuki, and Geely, and exports to more than 10 countries worldwide. This global footprint is built on consistent delivery, competitive factory-direct pricing, and the ability to scale production volumes without compromising quality.
With typical delivery times of 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, DIAN STAMPING offers the speed and reliability that automotive production schedules demand.
Factory-Direct Advantage
As a true factory rather than a trading company, DIAN STAMPING passes the cost savings of direct manufacturing directly to its customers. Customization is available from 2D drawings, 3D data, or physical samples, and the company's engineering team collaborates closely with clients to optimize part designs for manufacturability. This design-for-manufacturing (DFM) approach reduces tooling costs, shortens lead times, and improves part quality from the first shot.
