Precision Automotive Stamping Dies & Sheet Metal Parts – Why Dian Stamping Is the Partner You Can Trust

A Manufacturing Facility Built for Scale and Precision

Dian Stamping operates from a facility spanning approximately 50,000 m², including a dedicated die workshop of 4,000 m². The company's annual capacity reaches around 2,000 sets of medium and small stamping dies, with an annual die turnover of approximately RMB 50 million. A new 35,000 m² facility featuring advanced press lines and coating capabilities is already in development, further expanding the company's production capacity to meet growing global demand.

The company's workforce of approximately 110 employees includes 35 experienced die designers and technicians, ensuring that every project benefits from deep technical expertise from the design stage through to final tryout. This blend of skilled manpower and modern infrastructure positions Dian Stamping as one of the most capable stamping die manufacturers serving the international automotive industry.

Comprehensive Die Solutions for Every Automotive Application

Dian Stamping specializes in three primary types of stamping dies, each engineered to meet specific production requirements:

Progressive Dies — Ideal for high-volume production of complex parts, progressive dies perform multiple operations (blanking, forming, punching, and trimming) in a single press stroke, dramatically improving efficiency and consistency. These are widely used for body-in-white components, brackets, and structural reinforcements.

Transfer Dies — Designed for larger and more complex parts, transfer dies move the workpiece from station to station using mechanical transfer systems. This approach is particularly suited for deep-drawn panels, door inner panels, and structural members requiring multiple forming stages.

Tandem / Multi-Station Dies — For medium-to-high volume production runs requiring flexibility, tandem dies allow independent die stations to be set up in a press line, enabling quick changeover and efficient production of large body panels.

The company's die portfolio covers a full spectrum of automotive applications, including body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems. Materials processed include multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel.

Beyond Dies: Integrated Quality Assurance and Assembly Solutions

What sets Dian Stamping apart from many stamping die manufacturers is its ability to provide end-to-end solutions that extend well beyond the die itself. The company offers four integrated product lines:

Stamping Dies

Precision progressive, transfer, and tandem dies for complex automotive and industrial parts.

Sheet Metal Parts

High-volume production stamped parts, custom metal fabrication, and welding assemblies for automotive and household appliance industries.

Checking Fixtures

High-precision, GD&T-oriented inspection fixtures that enable fast, reliable dimensional verification of stamped components. As the company notes, press dies and checking fixture are necessary as a set — eliminating individual measurement differences and ensuring consistent quality across every production run.

Welding Jigs — Custom fixtures for accurate, repeatable positioning during welding and assembly, supporting body-in-white, chassis, and seating system assembly operations.

Quality Management and Global Certifications

Quality assurance at Dian Stamping is built on a foundation of ISO 9001-certified quality management practices, with processes aligned to IATF 16949-oriented automotive manufacturing standards. This commitment to quality is reflected in the company's customer roster, which includes internationally recognized automotive brands such as KIA, BYD, Toyota, Honda, Suzuki, and Geely. With exports reaching more than 10 countries, Dian Stamping has demonstrated its ability to consistently meet the stringent quality, delivery, and cost requirements of global automotive supply chains.

Flexible Customization and Fast Lead Times

Understanding that every automotive program has unique requirements, Dian Stamping offers flexible customization options. Customers can submit specifications via 2D drawings, 3D data, or physical samples, and the company's engineering team will develop a tailored tooling solution. Prototype services are also available for new program development.

Typical lead times are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity. The company's direct factory model ensures competitive pricing — customers pay for manufacturing capability, not intermediary margins. Free metal samples may be offered upon request (with freight paid by the customer), allowing potential partners to evaluate quality firsthand before committing to full-scale production.
