Over Two Decades of Stamping Excellence

Established in 2003 in Huangyan, Taizhou, Zhejiang Province, LINHAI DIAN MOULD CO., LTD (Dian Stamping) has built a reputation as one of China's most reliable stamping die manufacturers. With more than 20 years of hands-on industry experience, the company has served globally recognized automotive brands including KIA, BYD, Toyota, Honda, Suzuki, and Geely, exporting to over 10 countries worldwide.

What sets Dian Stamping apart is its commitment to being a true factory — not a trading company. This means clients get direct factory pricing, full quality control, and transparent communication throughout every project phase.

Comprehensive Manufacturing Capabilities Under One Roof

Dian Stamping operates a modern facility spanning approximately 50,000 m², with a dedicated die workshop of 4,000 m². The company employs around 110 skilled professionals, including approximately 35 die designers and technicians. This scale allows for an impressive annual capacity of about 2,000 sets of medium and small stamping dies, with an annual die turnover of approximately RMB 50 million.

The company's capabilities cover the entire manufacturing spectrum — from tool and die making to stamping, welding, assembly, checking fixtures, and welding jigs. A planned 35,000 m² facility featuring new press and coating lines is also underway, signaling continued investment in growth and modernization.

A Complete Product Portfolio for Automotive Applications

Dian Stamping's product range covers four critical areas of automotive manufacturing. As a dedicated sheet metal parts supplier, the company provides end-to-end solutions from raw material to finished assembly-ready components.

Stamping Dies: Precision progressive, transfer, and tandem stamping tooling for complex automotive and industrial parts. Application areas include body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems.

Sheet Metal Parts: High-volume production of automotive and household-appliance stampings, custom metal parts, and welding assemblies. Materials range from high-strength steel and aluminum to stainless steel and galvanized steel.

Checking Fixtures: High-precision, GD&T-oriented inspection fixtures designed to verify dimensional accuracy of stamped components and welded assemblies, eliminating measurement variability and ensuring consistent quality.

Welding Jigs: Custom welding fixtures and positioning tools for accurate, repeatable production and assembly operations, supporting both manual and automated welding processes.

Quality Systems and Customization That Matter

Dian Stamping operates under an ISO 9001 quality management system with IATF 16949-oriented automotive manufacturing practices. Every stamped component and die is subject to rigorous inspection protocols to meet OEM specifications.

Customization is a core strength. The company can work from 2D drawings, 3D data, or physical samples to create precisely matching tooling and parts. Prototype services are available for new vehicle programs, and free metal samples can be provided upon request (with freight paid by the customer).
