Quality Assurance: More Than Just a Certificate
Dian Stamping operates under an ISO 9001 quality management system and follows IATF 16949-oriented automotive manufacturing practices. But quality at Dian goes beyond certification. The company's in-house inspection capabilities include the use of precision checking fixture tools designed to GD&T standards, enabling fast and reliable verification of every produced part. This eliminates the individual measurement errors that can occur with traditional hand tools and ensures that every shipment meets the tight tolerances that automotive OEMs require.
Customization, Prototyping, and Flexible Delivery
As a factory-direct manufacturer — not a trading company — Dian Stamping offers genuine customization services. Customers can submit requirements in the form of 2D drawings, 3D CAD data, or even physical samples, and the company's experienced engineering team will develop the optimal tooling and production solution. Prototype services are also available for new product development programs.
Typical delivery timelines are competitive: approximately 30–40 days for steel stamping dies and around 70 days for casting stamping dies, depending on project complexity. The company also offers free metal samples (with freight paid by the customer) so that buyers can evaluate material quality and workmanship before committing to full-scale production.
A New Facility for the Next Stage of Growth
Dian Stamping is currently expanding its manufacturing footprint with a planned new 35,000 m² facility featuring advanced press lines and coating lines. This investment reflects the company's commitment to staying at the forefront of automotive stamping technology and meeting the growing demand for high-quality, cost-competitive tooling and stamped parts from global customers.
