When sourcing a partner for stamping die manufacturing, automotive OEMs look for more than just tooling. They need a partner who can deliver precision, consistency, and full-spectrum manufacturing support. For over two decades, DIAN STAMPING (Linhai Dian Mould Co., Ltd.) has been exactly that partner for global automotive brands including KIA, BYD, Toyota, Honda, Suzuki, and Geely.

A Legacy of Precision in Stamping Die Manufacturing

Founded in 2003 and headquartered in Linhai, Zhejiang, DIAN STAMPING operates a 50,000-square-meter facility with a dedicated team of over 110 professionals, including 35 mold designers and technicians. The company produces approximately 2,000 sets of stamping dies each year, earning its reputation as one of China's most reliable stamping die manufacturers for the automotive sector.

The company's expertise covers the full spectrum of tooling — progressive dies for high-volume, complex parts; transfer dies for large panels; tandem dies for multi-operation sequences; and custom die designs for specialized applications. Lead times are competitive: steel stamping dies delivered in 30 to 40 days and cast stamping dies in approximately 70 days.

Beyond Dies: A True Metal Stamping Parts Manufacturer

What sets DIAN STAMPING apart from typical tooling shops is its vertically integrated manufacturing capability. The company is not just a die maker — it is a full-service metal stamping parts manufacturer capable of taking projects from prototype through mass production.

The service chain includes:

• Sheet metal stamping and forming
• Welding assembly and integration
• Powder coating and e-coating
• Final assembly and quality inspection

This end-to-end approach means customers receive production-ready components, not just dies. It reduces supply chain complexity, shortens time-to-market, and ensures consistent quality across every stage of production.

Certified Quality for Automotive Standards

DIAN STAMPING holds both ISO 9001 and IATF 16949 certifications — the gold standard for automotive quality management. The company is also recognized as a National High-Tech Enterprise and a Zhejiang Province Science & Technology SME, with an in-house R&D laboratory dedicated to continuous improvement. Its checking fixtures and welding jigs are designed to GD&T standards, ensuring every stamped part meets the tight tolerances required by modern vehicle platforms.

Materials Expertise Across Diverse Applications

DIAN STAMPING works with a wide range of materials to meet the demands of today's automotive engineering:

These materials are processed into components for critical vehicle systems: body-in-white structures, seat frames, door panels, fuel tank systems, exhaust components, chassis parts, instrument panel supports, and battery enclosures for electric vehicles. Each application demands a different combination of material properties, die design approach, and process control — and DIAN STAMPING has the track record to deliver across all of them.

Serving the EV Revolution

As the automotive industry accelerates toward electrification, DIAN STAMPING has invested in the tooling and manufacturing capabilities required for electric vehicle battery enclosure systems. These large, complex stamping and welding assemblies demand exceptional precision and structural integrity — exactly the kind of challenge that a partner with over two decades of die-making experience is built to solve.
