In the competitive world of automotive manufacturing, the quality of your tooling directly determines the quality of your finished parts. Choosing the right partner for automotive stamping dies is not just a procurement decision — it is a strategic investment in production efficiency, dimensional accuracy, and long-term supply chain reliability.
Who Is DIAN Stamping?
LINHAI DIAN MOULD CO., LTD — known globally as DIAN Stamping — is a China-based manufacturer that has been dedicated to the design and production of precision stamping tooling, stamped sheet-metal parts, checking fixtures, and welding jigs since 2003.

Comprehensive Product and Service Portfolio
DIAN Stamping is not a single-product supplier. The company's offerings span the full spectrum of metal forming and assembly tooling, making it a true one-stop manufacturing partner:
- Stamping Dies — Precision progressive, transfer, and tandem dies for complex automotive and industrial parts, including body-in-white, door systems, seating systems, and chassis components.
- Sheet Metal Parts — High-volume stamped and fabricated components for automotive, household appliance, and industrial applications, with options for laser cutting, bending, welding, and powder coating.
- Checking Fixtures — GD&T-oriented inspection fixtures designed to verify dimensional accuracy of stamped parts, eliminating individual measurement variation and ensuring quality at the production line.
- Welding Jigs — Custom fixtures for accurate, repeatable positioning during welding and assembly, supporting consistent quality in high-volume production environments.
Application areas served include body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems — covering virtually every structural and cosmetic metal component in a modern vehicle.
Precision Engineering Through Progressive Die Stamping
A key differentiator for DIAN is its expertise in progressive die stamping. This high-efficiency process allows multiple operations — such as blanking, forming, coining, and piercing — to be performed in a single press stroke across a series of stations. The result is faster cycle times, lower per-part cost, and exceptional dimensional consistency across large production runs.
Whether you need progressive dies for high-volume body panels, transfer dies for deep-drawn structural components, or tandem dies for large and medium-sized complex parts, DIAN's engineering team has the technical depth to deliver tooling that performs reliably from the first hit to the millionth.
Quality Assurance and Certifications
Quality is embedded in every stage of DIAN's manufacturing process. The company operates under an ISO 9001 quality management system and follows IATF 16949-oriented automotive manufacturing and quality practices. Rigorous in-process inspections, 3D scanning (CMM), and strain analysis are standard procedures to ensure every die and stamped part meets OEM specifications.
DIAN also offers free metal samples for evaluation (with freight paid by the customer), prototype services, and full customization from 2D drawings, 3D data, or physical samples — giving buyers complete confidence before committing to full-scale production.
