1. In-House Die Design and Engineering Capability

One of the strongest predictors of a successful stamping program is whether the manufacturer designs and engineers its own tooling. Suppliers who outsource die design introduce an additional coordination layer that extends lead times and fragments accountability. DIAN STAMPING maintains an in-house team of approximately 35 die designers and technicians, utilizing advanced CAD/CAM software including AutoCAD, SolidWorks, and CATIA. This integrated approach ensures that every progressive die stamping tool is developed under a single project team, from initial concept through tryout and production, enabling faster iteration and tighter quality control.

2. Press Capacity and Production Scale

A manufacturer's press capacity must match the specific forming requirements of your components — not just a headline tonnage figure. Transfer presses, progressive die lines, and tandem lines serve fundamentally different part families. DIAN STAMPING operates a modern facility spanning approximately 50,000 m², with a dedicated die workshop of approximately 4,000 m². The company's annual capacity reaches roughly 2,000 sets of medium and small stamping dies, with an annual die turnover of approximately RMB 50 million. A planned 35,000 m² expansion featuring new press and coating lines further underscores the company's commitment to scaling with its customers' needs.

3. Advanced Material Processing Capability

Modern vehicle programs increasingly specify advanced high-strength steel (AHSS), aluminum alloys, and specialty materials for lightweighting and crash performance. Each material grade demands specific tooling design, springback compensation strategies, and process parameter management. DIAN STAMPING has proven capability in processing multiphase steel, aluminum, custom rolled and welded plate, and stainless steel. Whether your project requires forming of high-tensile structural components or precision aluminum parts for EV platforms, the company's technical team has active production experience across these material categories.

4. Comprehensive Quality Management

In the automotive industry, quality certification is a baseline requirement, but the scope and depth of the quality system matters far more. DIAN STAMPING operates under ISO 9001 certification and follows IATF 16949-oriented automotive manufacturing and quality practices. The company's quality approach encompasses the full production chain — from incoming material inspection through in-process dimensional verification to final PPAP-level validation. For critical components, the company can supply checking fixtures designed to GD&T standards, ensuring that press dies and inspection fixtures are delivered as a matched set for rapid, repeatable dimensional verification.

5. Full-Service Capability Beyond Die Manufacturing

A true one-stop partner reduces the complexity of managing multiple suppliers across the production chain. DIAN STAMPING offers not only stamping die manufacturers expertise but also comprehensive downstream services: sheet metal stamping and fabrication, laser cutting, bending, welding (including robotic MIG and spot welding), powder coating, and assembly. This vertically integrated model means that a single partner can take your project from die design and tooling fabrication through prototype validation to high-volume production of finished stamped parts, checking fixtures, and welding jigs.

6. Proven Track Record and Global Reach

When evaluating a stamping partner, past program performance is the most reliable indicator of future results. Established in 2003 in Huangyan, Taizhou, Zhejiang Province, DIAN STAMPING brings more than 20 years of continuous operation in the automotive tooling and stamping industry. The company's customer roster includes major global OEMs such as KIA, BYD, Toyota, Honda, Suzuki, and Geely, and its products are exported to over 10 countries. Typical delivery lead times are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, subject to project scope and complexity.

7. Customization and Prototyping Flexibility

Every automotive program has unique requirements, and the ability to accommodate custom specifications is a hallmark of a capable manufacturing partner. DIAN STAMPING accepts customization from 2D drawings, 3D CAD data, or physical samples. Prototype services are available to validate designs before committing to full production tooling. The company also offers free metal samples (with freight paid by the customer) to help buyers evaluate material quality and workmanship before placing production orders. This flexibility makes the company an accessible partner for both established OEMs and emerging EV manufacturers.
