When sourcing critical tooling for a new vehicle program, automotive OEMs and Tier 1 suppliers face a fundamental question: which stamping die manufacturers can deliver the precision, capacity, and consistency required for high-volume production? The answer increasingly points to China-based manufacturers with deep engineering expertise and vertically integrated facilities. One such manufacturer, LINHAI DIAN MOULD CO., LTD (Dian Stamping Company), has been serving the global automotive industry for over two decades.
Two Decades of Automotive Tooling Excellence
Established in 2003 in Huangyan, Taizhou, Zhejiang Province, Dian Stamping has built a reputation as a reliable partner for automotive stamping dies and stamped components. With more than 20 years of industry experience, the company has supplied tooling to major automotive brands including KIA, BYD, Toyota, Honda, Suzuki, and Geely, and exports its products to more than 10 countries worldwide. This track record demonstrates not only technical capability but also the ability to meet the rigorous quality and delivery standards demanded by global OEMs.
Manufacturing Scale and Capability
Dian Stamping operates a modern facility covering approximately 50,000 m², with a dedicated die workshop of roughly 4,000 m². The company employs around 110 skilled professionals, including approximately 35 die designers and technicians. This engineering team drives an annual production capacity of about 2,000 sets of medium and small stamping dies, with an annual die turnover of approximately RMB 50 million.
The company is also investing in future growth with a planned 35,000 m² facility featuring new press and coating lines, ensuring that capacity continues to scale alongside customer demand.
Key capacity highlights:
- 50,000 m² modern manufacturing facility
- ~110 employees, including 35+ die engineers
- ~2,000 sets of stamping dies annual capacity
- New 35,000 m² expansion with press and coating lines
Comprehensive Die and Tooling Portfolio
Dian Stamping offers a full spectrum of tooling solutions for automotive body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems. The die portfolio includes:
- Progressive dies — for high-volume, multi-operation stamping in a single pass
- Transfer dies — for complex, large-part forming with tight dimensional control
- Tandem and multi-station dies — for flexible, sequenced production lines
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.
Beyond Dies: Integrated Services for Complete Part Production
What sets Dian Stamping apart is its ability to provide end-to-end manufacturing solutions that go beyond tooling alone. The company’s service portfolio spans four integrated areas:
Sheet Metal Parts — High-volume stamping production, sheet-metal fabrication, and welding assemblies for automotive and household appliance applications. The company handles everything from prototype development to mass production, with capabilities including progressive stamping, deep drawing, forming, laser cutting, and powder coating.
Checking Fixture — Precision inspection fixtures designed to GD&T standards, enabling rapid dimensional verification of stamped components and welded assemblies. Checking fixtures eliminate measurement variability and ensure consistent quality across production runs.
Welding Jig — Custom welding fixtures for accurate, repeatable positioning during assembly welding. These jigs support spot welding, arc welding, and robotic welding processes, ensuring dimensional accuracy in welded subassemblies.
This integrated approach means customers can source tooling, stamped parts, inspection fixtures, and welding jigs from a single supplier — reducing supply chain complexity, communication overhead, and total project cost.
Quality Systems and Certifications
Dian Stamping operates under an ISO 9001-certified quality management system and follows IATF 16949-oriented automotive manufacturing practices. The company’s quality assurance process includes in-line inspections, 3D scanning (CMM), and rigorous dimensional validation to meet OEM specifications. For customers requiring validated production processes, the company offers full PPAP (Production Part Approval Process) support.
Customization and Prototyping Services
As a factory-direct manufacturer — not a trading company — Dian Stamping offers complete design-to-production customization. Customers can submit requirements via 2D drawings, 3D CAD data, or physical samples, and the engineering team will develop the optimal tooling solution. Prototype services are available for new program development, and free metal samples can be provided (with freight paid by the customer). Typical delivery lead times are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity.
Why Global OEMs Trust Dian Stamping
In a competitive global market, automotive manufacturers choose Dian Stamping for several compelling reasons:
- Factory-direct pricing — Eliminate middleman margins and benefit from competitive cost structures
- 20+ years of OEM experience — Proven track record with KIA, BYD, Toyota, Honda, and other global brands
- Full vertical integration — From die design and CNC machining to tryout, stamping, and assembly under one roof
- Engineering depth — 35+ die designers and technicians delivering complex tooling solutions
- Multi-material processing — Expertise in high-strength steel, aluminum, stainless steel, and advanced alloys
- Expanding capacity — New 35,000 m² facility for increased production volume and faster lead times
