In the fast-paced world of automotive manufacturing, the quality of your tooling directly determines the quality of your final product. Every body panel, chassis component, and structural reinforcement begins its life inside a stamping die. Choosing the right partner for progressive die stamping and precision tooling is not just a procurement decision — it is a strategic one that affects cost, lead time, and production reliability. For more than two decades, DIAN STAMPING (Linhai Dian Mould Co., Ltd.) has been that trusted partner for some of the world's largest automotive names.
A Foundation Built on Experience
Established in 2003 in Huangyan, Taizhou, Zhejiang Province — a region long recognized as China's mould manufacturing hub — DIAN STAMPING has grown from a specialized tooling workshop into a comprehensive, one-stop manufacturing partner for the automotive industry. The company's 20+ years of hands-on experience in stamping die manufacturers and precision metal forming is reflected in the trust it has earned from OEM clients including KIA, BYD, Toyota, Honda, Suzuki, and Geely, with exports reaching more than 10 countries across Asia, Europe, and the Americas.
This is not a trading company or a middleman. DIAN STAMPING is a factory, and it operates with the factory-direct pricing, quality control, and engineering depth that only a true manufacturer can offer.
Manufacturing Scale & Technical Capabilities
DIAN STAMPING's manufacturing footprint is substantial. The company operates a modern facility covering approximately 50,000 m², with a dedicated die workshop of about 4,000 m². A planned 35,000 m² expansion featuring new press lines and advanced coating capabilities is already underway, signaling the company's commitment to continuous investment in production capacity.
The company's engineering team includes approximately 35 die designers and technicians who specialize in the full spectrum of automotive stamping dies — from progressive dies and transfer dies to tandem or multi-station dies. They work with a wide range of materials including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel, covering application areas such as body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems.
Four Core Service Pillars
1. Stamping Dies — Precision progressive, transfer, and tandem stamping tooling for complex automotive and industrial parts. The company's annual die turnover is approximately RMB 50 million, reflecting both the volume and value of the tooling it delivers.
2. Sheet Metal Parts — From automotive body panels to household appliance stampings, DIAN STAMPING offers custom sheet metal fabrication, laser cutting, forming, welding, and assembly. Materials range from cold-rolled steel and galvanized steel to aluminum and stainless steel, with secondary operations including powder coating and surface finishing.
3. Checking Fixtures — High-precision, GD&T-oriented inspection fixtures that eliminate individual measurement variation. Every stamping die set should be paired with a corresponding checking fixture to ensure dimensional accuracy and repeatability in production.
4. Welding Jigs — Custom-designed welding fixtures and supporting services for accurate, repeatable positioning during welding and assembly operations, ensuring consistent quality across production runs.
Quality Systems That Deliver Consistency
DIAN STAMPING operates under an ISO 9001 quality management system and follows IATF 16949-oriented automotive manufacturing and quality practices. The company's commitment to quality is visible at every stage — from die design and tryout through production stamping, inspection, and delivery. In-line inspections, 3D scanning (CMM), and strain analysis are standard procedures that ensure every tool and part meets OEM specifications.
Typical delivery timelines are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity. Prototype services are available, and customization can be performed from 2D drawings, 3D data, or physical samples. Free metal samples can also be provided, with freight paid by the customer.

The Cost of Choosing the Wrong Partner
In the B2B stamping industry, the difference between a reliable die manufacturer and an average one can translate into months of production delays, rejected parts, and costly rework. A poorly designed progressive die may produce acceptable parts initially, but its service life, maintenance frequency, and long-term dimensional stability are what separate a true partner from a commodity supplier. DIAN STAMPING's 20-year track record with global automotive brands demonstrates that longevity and reliability are not accidents — they are the result of disciplined engineering, continuous investment, and a customer-first approach.
