In automotive manufacturing, the quality of tooling and stamped components directly affects vehicle safety, production efficiency, and cost control. As global OEMs continue to tighten quality standards and seek reliable supply chains, finding a partner with genuine manufacturing depth has never been more important. LINHAI DIAN MOULD CO., LTD — operating under the brand DIAN STAMPING — has spent more than two decades earning its reputation as one of China's experienced stamping die manufacturers, serving automotive leaders across Asia and beyond.

Two Decades of Hands-On Manufacturing Experience

Founded in 2003 in Huangyan, Taizhou, Zhejiang Province, DIAN STAMPING began as a specialized mold workshop and has since grown into a full-scale manufacturing enterprise. The company's 20+ years of industry experience are reflected in every project it undertakes. With a team of 110 employees, including 35 skilled die designers and technicians, the company has supplied automotive stamping dies to well-known OEMs such as KIA, BYD, Toyota, Honda, Suzuki, and Geely, while building an export footprint that spans more than 10 countries.

A Complete Ecosystem Under One Roof

One of the key advantages DIAN STAMPING offers is its end-to-end manufacturing capability. The company operates as a true factory, not a trading intermediary, and handles every stage of production in-house. Its four core product categories — precision stamping dies, sheet metal stamped parts, checking fixtures, and welding jigs — cover the full spectrum of automotive part manufacturing needs.

This integrated approach allows customers to source tooling, production parts, inspection fixtures, and assembly jigs from a single qualified partner. For buyers looking for custom sheet metal parts alongside their die requirements, this eliminates the complexity of managing multiple suppliers and ensures consistent quality across the entire production chain.

Manufacturing Scale and Precision

DIAN STAMPING's production base covers approximately 50,000 square meters, including a dedicated 4,000 m² die workshop. The company is currently expanding with a new 35,000 m² facility that will feature additional press lines and in-house powder coating capability. With an annual output of approximately 2,000 sets of medium and small stamping dies and a reported annual die turnover of around RMB 50 million, the company operates at a scale that can support both prototype development and high-volume production runs.

The company processes a wide range of materials including multiphase steel, aluminum alloys, custom rolled steel, welded plate, and stainless steel — covering critical automotive application areas such as body-in-white, door systems, seating systems, instrument panels, fuel tanks, exhaust systems, clutch systems, and chassis systems.

Certified Quality and Industry Recognition

Quality assurance is embedded in every stage of DIAN STAMPING's operations. The company holds IATF16949, ISO 9001, and TUV certifications, and has been recognized as a National High-Tech Enterprise and a Zhejiang Provincial Technology-based SME. Its high-tech development laboratory supports continuous improvement in die design, material processing, and quality control. Typical delivery timelines are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, subject to project complexity.

Cost-Effective Solutions Without Compromising Quality

As a factory-direct supplier, DIAN STAMPING offers competitive pricing that reflects genuine manufacturing costs rather than trading margins. The company supports non-standard OEM/ODM projects across automotive, electrical, hardware, and home appliance industries. Free solutions, tooling consultation, and sampling services are available for qualified inquiries, making it easier for buyers to evaluate capability before committing to full-scale production.
