When sourcing precision tooling and stamped components for vehicle production, the quality of your automotive stamping dies directly determines the dimensional accuracy, structural integrity, and cost-efficiency of every part that leaves your assembly line. Choosing the right manufacturing partner is therefore one of the most critical decisions an automotive OEM or Tier supplier can make.
Over Two Decades of Specialized Experience
Established in 2003 in Huangyan, Taizhou, Zhejiang Province, LINHAI DIAN MOULD CO., LTD (DIAN STAMPING) has accumulated more than 20 years of focused expertise in the design and manufacture of progressive die stamping tooling, transfer dies, and tandem dies. The company's modern facility spans approximately 50,000 m², including a dedicated die workshop of 4,000 m², and employs around 110 skilled professionals, among whom approximately 35 are die designers and technicians. This depth of engineering talent ensures that every tool is developed with precision and purpose.
Comprehensive Capabilities Under One Roof
DIAN STAMPING is not a trading company — it is a full-fledged factory offering end-to-end manufacturing services. Its capabilities span tool and die manufacturing, stamping, welding, assembly, and the production of checking fixtures and welding jigs. The company processes a wide range of materials, including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel, making it a versatile partner for diverse automotive applications.
With an annual capacity of approximately 2,000 sets of medium and small stamping dies and a reported annual die turnover of around RMB 50 million, DIAN STAMPING brings both scale and reliability to every project. A planned 35,000 m² facility featuring new press and coating lines will further expand its production capabilities.
Four Core Product Categories Serving the Automotive Industry
1. Stamping Dies
Precision progressive, transfer, and tandem dies for large and medium-sized complex automotive parts. Applications include body-in-white components, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems.
2. Sheet Metal Parts
Automotive and household-appliance stamping, sheet-metal fabrication, custom metal parts, and welding assemblies. From chassis seats to refrigerator components, DIAN STAMPING delivers high-quality formed parts with tight tolerances.
3. Checking Fixtures
High-precision, GD&T-oriented inspection fixtures designed to verify that stamped components and welded assemblies conform to specified dimensions. A checking fixture eliminates individual measurement variation and enables rapid, repeatable quality inspection of large production volumes.
4. Welding Jigs
Custom welding fixtures that ensure accurate positioning and repeatable weld quality during production and assembly. These jigs are essential for maintaining dimensional consistency in welded sub-assemblies and body structures.
Proven Quality Systems and Global Customer Base
DIAN STAMPING operates under an ISO 9001 quality management system and follows IATF 16949-oriented automotive manufacturing practices. The company serves OEM customers including KIA, BYD, Toyota, Honda, Suzuki, and Geely, and exports its products to more than 10 countries worldwide. This track record demonstrates a consistent ability to meet the rigorous quality, delivery, and cost requirements of global automotive manufacturers.
Flexible Customization and Competitive Delivery
