From Die Design to Assembly: Dian Stamping's Complete Automotive Manufacturing Ecosystem
How one Chinese manufacturer delivers precision tooling, stamped components, inspection fixtures, and welding solutions under one roof
For automotive OEMs and Tier-1 suppliers, managing a fragmented supply chain for dies, stamped parts, checking fixtures, and welding jigs creates inefficiencies, quality variation, and extended lead times. Dian Stamping, operating under LINHAI DIAN MOULD CO., LTD, offers a unified alternative — a single facility in Zhejiang, China, that covers the entire manufacturing chain from die design to assembled components.
Established in 2003, the company has accumulated over two decades of hands-on experience serving global automotive brands including KIA, BYD, Toyota, Honda, Suzuki, and Geely. With exports reaching more than 10 countries, Dian Stamping positions itself as a factory-direct partner for complex automotive tooling and production.
A Manufacturing Facility Built for Scale
The company's modern campus spans approximately 50,000 m², with a dedicated die workshop of about 4,000 m² and a planned additional 35,000 m² facility featuring new press lines and coating capabilities. This infrastructure supports an annual output of roughly 2,000 sets of medium and small stamping dies, with annual die turnover reported at approximately RMB 50 million.
A team of around 110 employees — including roughly 35 die designers and technicians — ensures that each project receives the engineering attention it requires. The company processes a wide range of materials, including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel.
Core Capability 1: Precision Stamping Dies
As a specialized stamping die manufacturer, Dian Stamping designs and builds progressive dies, transfer dies, and tandem/multi-station dies for large and medium-sized complex automotive parts. Application areas include body-in-white structures, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, and chassis components.
Each die is engineered for high-volume production with tight dimensional tolerances, leveraging in-house design capabilities using industry-standard CAD/CAM software. The company's automotive stamping dies are built to handle high-strength steel (HSS) and advanced high-strength steel (AHSS), enabling lighter, stronger vehicle structures.
Core Capability 2: Stamped Sheet Metal Parts
Beyond die manufacturing, Dian Stamping operates stamping presses capable of producing both automotive and household appliance sheet metal parts. The product range covers brackets, panels, hinges, structural reinforcements, and complex assemblies — all produced with consistent quality across high-volume runs.
The company's sheet metal stamping dies support a wide variety of materials and thicknesses, from thin-gauge automotive panels to thicker structural components. Secondary operations such as laser cutting, bending, welding, and surface coating are available in-house, reducing the need for multiple suppliers.
One-Stop Advantage
Customers who order both stamping dies and production parts from Dian Stamping benefit from faster die tryout, immediate feedback on part quality, and streamlined logistics — all under a single quality management system.
Core Capability 3: Checking Fixtures for Quality Assurance
Every stamped component needs to be verified against design specifications. Dian Stamping designs and manufactures high-precision checking fixtures that enable rapid, repeatable inspection of complex geometries. A checking fixture confirms whether a manufactured workpiece meets the determined dimensions, eliminating individual measurement variations and speeding up quality control at production sites.
As the company's product documentation emphasizes, press dies and checking fixtures are necessary as a set — and Dian Stamping delivers both, ensuring that tooling and inspection go hand in hand from the start of production.
Core Capability 4: Welding Jigs and Assembly Fixtures
Precision welding requires precise positioning. Dian Stamping provides custom welding jigs designed to hold components in exact alignment during welding operations, ensuring repeatable weld quality and dimensional accuracy. The company's welding jig solutions support applications ranging from body-in-white assembly to subframe and chassis welding.
Combined with its checking fixture capabilities, Dian Stamping offers a complete quality assurance loop: design the die → stamp the part → inspect with fixture → weld with jig → deliver the assembly.
Quality Management and Certifications
Dian Stamping operates under an ISO 9001 quality management system and follows IATF 16949-oriented automotive manufacturing practices. The facility conducts in-line inspections, 3D scanning (CMM), and strain analysis to meet OEM specifications. Customers can customize parts from 2D drawings, 3D data, or physical samples, and prototype services are available for new program development.
Typical delivery timelines are 30-40 days for steel stamping dies and approximately 70 days for casting stamping dies, subject to project scope and complexity. Free metal samples may be offered, with freight paid by the customer.
Why Choose a Factory-Direct Partner?
Dian Stamping identifies itself as a factory, not a trading company — a distinction that matters for cost, communication, and quality control. By working directly with the manufacturing source, customers gain:
- Factory pricing — no intermediary markups
- Direct engineering communication — faster problem resolution during die design and tryout
- End-to-end accountability — one partner responsible for dies, production, inspection, and assembly
- Long-term supply relationships — built on two decades of serving global automotive brands
