A closer look at how a 20-year China-based manufacturer delivers quality, scale, and reliability for automotive stamping projects worldwide

Over Two Decades of Automotive Tooling Experience

DIAN STAMPING was established in 2003 and has since accumulated more than 20 years of hands-on experience in the design and manufacture of precision stamping tooling. The company's client list includes some of the world's most demanding automotive brands: KIA, BYD, Toyota, Honda, Suzuki, and Geely. Having passed the rigorous supplier qualification processes of these OEMs, DIAN STAMPING has demonstrated its ability to meet strict quality, delivery, and cost targets consistently.

The company's products are exported to more than 10 countries, serving not only automotive OEMs but also Tier-1 suppliers and industrial customers across multiple sectors. This global footprint is a testament to the company's reliability and its ability to navigate the complexities of international logistics and cross-border quality standards.

Comprehensive Manufacturing Capabilities Under One Roof

One of the key differentiators of DIAN STAMPING is its ability to offer end-to-end services — from die design and fabrication to stamping production, welding, assembly, and inspection. This integrated approach eliminates the coordination headaches that often arise when working with multiple suppliers for tooling and production.

Stamping Dies: The company specializes in stamping die manufacturers expertise covering progressive dies, transfer dies, and tandem/multi-station dies. These tooling solutions are designed for medium to large complex parts used in body-in-white, door systems, seating systems, instrument panels, exhaust systems, and chassis structures. The die workshop spans approximately 4,000 m² and is equipped with advanced CNC machining centers, EDM equipment, and tryout presses.

Sheet Metal Parts: Beyond tooling, DIAN STAMPING produces high-volume stamped sheet metal components for both automotive and household appliance applications. The company processes a wide range of materials including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel — with thicknesses and geometries tailored to each customer's specifications.

Checking Fixtures and Welding Jigs: Quality assurance is a critical part of any stamping operation. DIAN STAMPING designs and manufactures precision checking fixtures based on GD&T principles to verify dimensional accuracy of stamped parts. The company also produces custom welding jigs for accurate, repeatable assembly operations — covering everything from spot welding jigs to rotating welding jigs and chassis welding jigs.

Precision Engineering Meets Production Scalability

For any progressive die stamping project, the quality of the die directly determines the consistency and accuracy of the final stamped parts. DIAN STAMPING employs a team of approximately 35 die designers and technicians who use advanced CAD/CAM software to develop tooling solutions optimized for high-volume production.

The company's quality management system is ISO 9001 certified, and the facility follows IATF 16949-oriented automotive manufacturing practices. This means every die and stamped part undergoes rigorous inspection — from first-article inspection to in-process SPC (Statistical Process Control) and final dimensional validation using CMM (Coordinate Measuring Machine) equipment.

DIAN STAMPING is also expanding its capacity with a planned 35,000 m² facility featuring new press lines, welding lines, and coating lines — a clear signal of the company's commitment to long-term growth and technological advancement.

Customization and Prototyping: From Concept to Production

Every automotive stamping project is unique. DIAN STAMPING accepts design inputs in multiple formats — 2D drawings, 3D CAD data, or physical samples — and works closely with customers to develop tooling solutions that meet their exact requirements. The company also offers prototype services, allowing customers to validate part designs before committing to full production tooling.

The typical delivery timeline is 30 to 40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on the complexity and scope of the project. Free metal samples are available (with freight paid by the customer), enabling buyers to evaluate material quality and surface finish firsthand.

Factory-Direct Pricing and Long-Term Partnership

As a factory-direct manufacturer — not a trading company — DIAN STAMPING offers competitive pricing that reflects actual production costs rather than intermediary markups. This direct relationship also means shorter communication chains, faster problem resolution, and greater transparency throughout the project lifecycle.

The company's flexible payment terms accommodate different project scales: 100% advance for orders under USD 1,000, and 40% T/T advance with balance before shipment for larger orders. This practical approach has helped DIAN STAMPING build long-term relationships with customers across Asia, Europe, the Middle East, and the Americas.
