The One-Stop Manufacturing Partner the Automotive Industry Needs
The global automotive supply chain demands more than just low costs. It demands precision, consistency, speed, and the ability to scale. Since 2003, LINHAI DIAN MOULD CO., LTD (Dian Stamping) has served these needs by offering a comprehensive suite of services: from designing and building automotive stamping dies and producing sheet metal parts, to supplying checking fixture solutions and welding jig systems. This vertically integrated approach eliminates the coordination headaches of managing multiple suppliers while ensuring quality at every stage of production.
Headquartered in Huangyan, Taizhou, Zhejiang Province, Dian Stamping operates a modern facility spanning approximately 50,000 m², including a dedicated die workshop of 4,000 m². With around 110 employees — of whom 35 are skilled die designers and technicians — the company has an annual capacity of roughly 2,000 sets of medium and small stamping dies. Its reported annual die turnover of approximately RMB 50 million reflects a steady, scalable operation that has earned the trust of brands like KIA, BYD, Toyota, Honda, Suzuki, and Geely, exporting to more than 10 countries worldwide.
Precision Stamping Dies: Where It All Begins
At the heart of Dian Stamping's offering is its die-making capability. The company designs and manufactures progressive dies, transfer dies, and tandem or multi-station dies for large and medium-sized complex automotive parts. These dies are used across a wide range of vehicle systems — body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems.
Material versatility is a key advantage. Dian Stamping processes multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel — enabling customers to meet evolving lightweighting and strength requirements. For automotive stamping dies, typical delivery is 30-40 days for steel dies and approximately 70 days for casting dies, depending on project complexity. The company also offers prototype services and accepts orders from 2D drawings, 3D CAD data, or physical samples.
Sheet Metal Parts: From Prototype to High-Volume Production
Beyond tooling, Dian Stamping is a full-fledged sheet metal parts manufacturer. Its stamping and fabrication services cover automotive body panels, structural reinforcements, brackets, hinges, and assemblies. The company also serves the household appliance industry, producing components for refrigerators, washing machines, ovens, and more.
Secondary operations — including laser cutting, bending, welding, deburring, and coating — are handled in-house, ensuring that parts arrive assembly-ready. Whether you need prototype sheet metal parts for validation or high-volume production runs, Dian Stamping's facility and experience deliver consistent quality with competitive factory-direct pricing.
Checking Fixtures: Ensuring Quality at Every Part
In automotive manufacturing, dimensional accuracy is non-negotiable. That is why stamping dies and checking fixtures always go hand in hand. Dian Stamping designs and manufactures high-precision, GD&T-oriented inspection fixtures that allow operators to quickly verify whether a stamped part meets design specifications.
A well-designed checking fixture eliminates individual measurement variation and enables rapid inspection of large batches — a critical advantage on busy production lines. By integrating checking fixture design and fabrication into its workflow, Dian Stamping gives customers an additional layer of quality assurance before parts move to assembly or shipment.
Welding Jigs: Repeatable Accuracy for Assembly Operations
Welding operations are only as good as the fixtures that hold the parts. Dian Stamping's custom welding jig solutions are designed to position components accurately and repeatedly, ensuring consistent weld quality across production runs. From simple locating fixtures to complex multi-axis welding jigs, the company supports a wide range of automotive and industrial assembly applications.
Combined with its welding and assembly services, these jigs enable Dian Stamping to deliver complete sub-assemblies that are ready for direct integration into OEM production lines — reducing lead times and simplifying the supply chain for its customers.
Quality Systems and Continuous Improvement
Dian Stamping operates under an ISO 9001 quality management system, with manufacturing practices aligned to IATF 16949 automotive standards. Rigorous in-process inspections, 3D scanning (CMM), and statistical process control (SPC) are applied throughout production. The company's commitment to quality is further reinforced by its planned 35,000 m² expansion facility, which will introduce new press lines and coating capabilities to meet growing demand.
As a factory-direct manufacturer — not a trading company — Dian Stamping offers transparent pricing, direct engineering communication, and the flexibility to customize solutions for each customer's unique requirements. Free metal samples are available upon request (freight paid by the customer).
