Founded in 2003, DIAN STAMPING brings more than 20 years of hands-on experience in the design and manufacture of automotive stamping dies. The company's customer roster reads like a who's who of the global automotive industry — KIA, BYD, Toyota, Honda, Suzuki, and Geely are among the OEMs that trust DIAN for their critical tooling and stamped components. With exports reaching more than 10 countries, the company understands the quality standards, delivery expectations, and communication protocols required to serve international clients effectively.

DIAN STAMPING is not a trading company — it is a full-fledged manufacturing facility with vertically integrated processes. The company's core capabilities span four major areas:

Beyond these core offerings, DIAN provides prototype services, powder coating, and finished product assembly, making it a true end-to-end manufacturing partner. The company's 4,000 m² die workshop houses modern machining and tryout equipment, while a planned 35,000 m² expansion will add new press lines, welding lines, and coating lines to further increase capacity.

In the automotive industry, certifications are not optional — they are the foundation of trust. DIAN STAMPING operates under an IATF 16949-oriented quality management system and holds ISO 9001 certification, along with TUV recognition. The company is also recognized as a National High-Tech Enterprise in China, reflecting its commitment to innovation and continuous improvement. These certifications, combined with rigorous in-process inspections and CMM-based dimensional verification, ensure that every die and stamped part meets the exacting standards of global automotive OEMs.

One of DIAN's key differentiators is its in-house capability to design and manufacture checking fixture systems. In stamping production, a checking fixture is essential for quickly verifying that complex stamped parts conform to design dimensions. DIAN's checking fixtures are built to eliminate individual measurement variations, allowing operators to inspect large volumes of parts rapidly and reliably. As the company states, "press dies and checking fixtures are necessary as a set" — and this integrated approach saves customers time, reduces scrap, and improves overall quality assurance.

DIAN STAMPING has demonstrated expertise in processing a wide range of materials, including:

These materials are applied across eight major automotive systems: body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems. This breadth of application experience makes DIAN a versatile partner capable of supporting both traditional ICE vehicle programs and new energy vehicle (NEV) platforms.

As a factory-direct manufacturer, DIAN STAMPING offers competitive pricing without compromising on quality. The company's typical delivery is 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, subject to project complexity. Customization is available from 2D drawings, 3D data, or physical samples, and free metal samples can be provided (with freight paid by the customer). This combination of factory pricing, flexible customization, and reliable lead times makes DIAN an attractive choice for OEMs and Tier suppliers looking to optimize their tooling budgets.

What sets DIAN STAMPING apart from other Chinese stamping suppliers is its holistic approach. The company does not just sell dies — it provides a complete manufacturing ecosystem: tool design, die manufacturing, tryout, sheet metal stamping, welding, assembly, and inspection. With affiliated companies including Linhai Diyao New Technology Co., Ltd. and Taizhou Elay International Trade Co., Ltd., DIAN has built a robust supply chain that handles everything in-house with zero outsourcing. This vertical integration translates into better quality control, shorter lead times, and lower costs for the customer.
