Over 20 Years of Automotive Stamping Excellence

Founded in 2003, Dian Stamping has evolved from a specialized die shop into a comprehensive one-stop manufacturing partner for the automotive industry. The company's headquarters and primary production base are located in Huangyan, Taizhou, Zhejiang Province 鈥?a region known for its robust manufacturing ecosystem. Over the past two decades, Dian Stamping has accumulated deep expertise in progressive die stamping, transfer die technology, and tandem die manufacturing, serving a diverse portfolio of automotive applications.

The company's manufacturing capabilities span the full production cycle: tool and die design, CNC machining, die assembly, tryout, and serial production. With a die workshop of approximately 4,000 m虏 and a planned 35,000 m虏 expansion featuring new press lines and coating lines, Dian Stamping is investing in the future of automotive metal forming. The facility processes a wide range of materials including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel, supporting both body-in-white and structural components.

Comprehensive Product Portfolio: From Dies to Finished Parts

Dian Stamping offers four integrated product categories that cover the entire value chain from tooling to production:

• Stamping Dies 鈥?Precision progressive, transfer, and tandem dies for complex automotive parts including body-in-white panels, door systems, seating components, instrument panels, and chassis parts. The company's die design team specializes in optimizing tool geometry for high-volume production with tight tolerances.
• Sheet Metal Parts 鈥?Custom stamped metal components for automotive and household appliance industries, including brackets, panels, hinges, reinforcement plates, and structural assemblies. Secondary operations such as laser cutting, welding, and surface coating are performed in-house.
• Checking Fixtures 鈥?High-precision, GD&T-oriented inspection fixtures that verify dimensional accuracy of stamped components and welded assemblies. As the industry adage goes, press dies and checking fixtures are always required as a set 鈥?Dian Stamping supplies both, ensuring seamless quality control integration.
• Welding Jigs 鈥?Custom welding fixtures designed for accurate, repeatable positioning and assembly of automotive sub-assemblies, from body components to chassis systems.

Application areas covered include body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems 鈥?making Dian Stamping a versatile partner for virtually any automotive stamping requirement.

Quality Assurance and Certifications

The company's quality approach encompasses the entire production process: from incoming material inspection and in-process dimensional checks to final validation using coordinate measuring machines (CMM) and functional tryout on production presses. This systematic approach has earned Dian Stamping the trust of OEM customers including KIA, BYD, Toyota, Honda, Suzuki, and Geely, with exports reaching more than 10 countries worldwide.

Customization is a core strength. Dian Stamping accepts customer specifications in the form of 2D drawings, 3D data, or physical samples, and offers prototype services to validate designs before committing to production tooling. Free metal samples can be provided for evaluation, with the customer covering freight charges.

Factory-Direct Pricing and Reliable Delivery

As a factory rather than a trading company, Dian Stamping offers direct pricing without intermediary markups. The company's reported annual die turnover of approximately RMB 50 million reflects its competitive position in the global tooling market. Typical delivery timelines are 30鈥?0 days for steel stamping dies and approximately 70 days for casting stamping dies, subject to project complexity and material requirements.

The company's ongoing facility expansion 鈥?including a new 35,000 m虏 plant with advanced press lines and coating equipment 鈥?will further increase production capacity and reduce lead times, enabling Dian Stamping to serve larger-scale programs and more demanding delivery schedules.

Global Customer Base and Market Reach

Dian Stamping's customer portfolio reads like a who's who of global automotive manufacturing. By serving KIA, BYD, Toyota, Honda, Suzuki, and Geely 鈥?six major OEMs 鈥?the company has demonstrated its ability to meet the engineering standards, quality benchmarks, and delivery requirements of both traditional combustion-engine vehicle programs and the rapidly growing new-energy vehicle (NEV) segment. With exports to more than 10 countries, Dian Stamping is a proven international supplier with a strong track record in cross-border tooling programs.
