Sourcing high-quality automotive stamping dies and precision sheet metal components from a single, reliable partner is one of the most critical decisions for automotive OEMs and Tier suppliers. The wrong choice can lead to tooling delays, inconsistent part quality, and costly production disruptions. As global automotive supply chains increasingly seek cost-competitive yet certified manufacturing partners, the demand for vertically integrated factories — rather than trading intermediaries — has never been higher.

Established in 2003 and headquartered in Taizhou, Zhejiang Province, DIAN STAMPING (LinhaI Dian Mould Co., Ltd.) has emerged as a trusted manufacturing partner for automotive OEMs worldwide. With over 20 years of industry experience, a 50,000 m² modern facility, and a growing portfolio of international clients including KIA, BYD, Toyota, Honda, Suzuki, and Geely, Dian Stamping delivers the full spectrum of tooling and production services under one roof.

Full In-House Capabilities: From Die Design to Finished Assembly

What sets Dian Stamping apart from many stamping die manufacturers is its end-to-end vertical integration. Unlike suppliers that outsource key processes, Dian Stamping handles every stage in-house — die design and development, sheet metal stamping, welding, powder coating, and finished product assembly. This integrated approach eliminates hand-off delays, reduces cost, and provides full traceability from raw material to final shipment.

The company's die workshop alone spans approximately 4,000 m² and is staffed by around 35 die designers and technicians. Annual die production capacity reaches approximately 2,000 sets of medium and small stamping dies, with an annual die turnover of around RMB 50 million. The company is also investing in a new 35,000 m² facility featuring advanced press lines and coating capabilities, further expanding its production capacity.

Comprehensive Product Portfolio

Dian Stamping offers a complete suite of products and services that cover virtually every need in the automotive metal forming value chain:

Application-specific solutions cover body-in-white systems, door systems, seating systems, instrument panels, exhaust systems, chassis systems, fuel tank systems, and clutch systems — making Dian Stamping a genuine one-stop partner for complex automotive projects.

Material Processing Expertise

Modern automotive design increasingly demands advanced materials. Dian Stamping has developed proven processing capabilities for multiphase steel (AHSS), aluminum alloys, custom rolled and welded plate, and stainless steel. This material versatility allows the company to serve a wide range of applications — from structural body components to lightweight chassis parts — without requiring customers to engage multiple suppliers.

Certified Quality, Factory Pricing

Dian Stamping operates under an ISO 9001-certified quality management system and follows IATF 16949-oriented automotive manufacturing practices. The company is also recognized as a National High-Tech Enterprise and a Zhejiang Provincial Technology-based SME, reflecting its commitment to continuous innovation and quality improvement.

As a direct factory rather than a trading company, Dian Stamping offers competitive pricing while maintaining full quality control across all production stages. Typical delivery is 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, subject to project requirements. Free metal samples are available upon request (freight at customer's cost).

Global Reach, Local Expertise

With exports to more than 10 countries and a customer base that includes some of the world's largest automotive brands, Dian Stamping understands the quality standards, documentation requirements, and communication expectations of international clients. The company offers OEM/ODM services for non-standard applications in automotive, electrical, hardware, and home appliance industries, and supports customization from 2D drawings, 3D data, or physical samples.
