In the competitive landscape of automotive manufacturing, selecting the right partner for automotive stamping dies is a strategic decision that directly impacts production quality, cost efficiency, and supply chain reliability. DIAN STAMPING, established in 2003 and headquartered in Huangyan, Taizhou, Zhejiang Province, has emerged as a trusted one-stop manufacturing partner for global automotive OEMs and Tier 1 suppliers.
Over Two Decades of Die Manufacturing Excellence
With more than 20 years of industry experience, DIAN STAMPING has built a reputation for delivering precision-engineered tooling solutions. The company's modern facility spans approximately 50,000 m², including a dedicated die workshop of 4,000 m², housing a team of around 110 skilled professionals — among them 35 die designers and technicians. This infrastructure supports an impressive annual capacity of approximately 2,000 sets of medium and small stamping dies, with a reported annual die turnover of around RMB 50 million.
As one of the leading stamping die manufacturers in China, DIAN STAMPING serves renowned OEM customers including KIA, BYD, Toyota, Honda, Suzuki, and Geely, and exports its products to more than 10 countries worldwide.
Comprehensive Product Portfolio and Capabilities
Unlike many suppliers that focus on a single product category, DIAN STAMPING offers a vertically integrated suite of manufacturing services under one roof:
- Stamping Dies — Precision tooling including progressive dies, transfer dies, and tandem dies for large and medium-sized complex automotive parts.
- Sheet Metal Parts — Automotive and household-appliance stamping, sheet-metal fabrication, custom metal parts, and welding assemblies — with expertise in progressive die stamping for high-volume production.
- Checking Fixture — High-precision, GD&T-oriented inspection fixtures for stamped components and assemblies, ensuring dimensional accuracy and quality control.
- Welding Jig — Custom welding fixtures and supporting services for accurate, repeatable production and assembly.
The company processes a wide range of materials including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel, covering diverse application areas such as body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems.
Integrated Quality Assurance and Certification
Quality is embedded in every stage of DIAN STAMPING's manufacturing process. The company operates under an ISO 9001 quality management system, while following IATF 16949-oriented automotive manufacturing and quality practices. Each die and component undergoes rigorous inspection using advanced checking fixtures and CMM (Coordinate Measuring Machine) verification to ensure compliance with OEM specifications.
Key Quality Highlights: In-line inspections, 3D scanning, and strain analysis to meet the strictest automotive safety standards. Free metal samples are available for evaluation (freight paid by customer).
Material and Process Versatility
DIAN STAMPING's manufacturing capabilities span a broad spectrum of processes and materials. From progressive die stamping and transfer die stamping to deep drawing, laser cutting, and custom fabrication, the company delivers solutions tailored to each project's unique requirements. Material options include:
- High-Strength Steel (HSS) — For structural components requiring crash performance and weight reduction.
- Aluminum Alloys — Lightweight solutions for modern vehicle platforms.
- Stainless Steel — Corrosion-resistant parts for exhaust and chassis systems.
- Cold-Rolled and Galvanized Steel — Cost-effective options for high-volume production.
End-to-End Service: From Design to Delivery
What sets DIAN STAMPING apart is its ability to manage the entire product lifecycle. The company accepts customization from 2D drawings, 3D data, or physical samples and offers prototype services for new vehicle programs. Typical delivery times are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, subject to project scope and complexity.
The company's integrated approach — combining tool and die manufacturing, stamping, welding, assembly, and inspection — enables faster turnaround, lower logistics costs, and single-point accountability for global OEMs.
New Facility Expansion for Growing Demand
To meet increasing global demand, DIAN STAMPING is investing in a planned 35,000 m² facility featuring new press lines and advanced coating lines. This expansion will significantly boost production capacity, enhance manufacturing efficiency, and support larger-scale OEM programs with shorter lead times.
