A Foundation Built on 23 Years of Stamping Expertise

Established in 2003 in Huangyan, Taizhou, Zhejiang Province, Dian Stamping has grown from a dedicated die shop into a full-scale manufacturing facility covering approximately 50,000 m². The company employs around 110 people, including 35 die designers and technicians, and produces approximately 2,000 sets of medium and small stamping dies annually. With an annual die turnover of approximately RMB 50 million and a new 35,000 m² facility already under development — featuring advanced press lines and coating capabilities — Dian Stamping is investing heavily in its future capacity.

As one of the leading stamping die manufacturers in China, the company serves OEM customers including KIA, BYD, Toyota, Honda, Suzuki, and Geely, and exports to more than 10 countries across Asia, Europe, and the Americas.

Core Capabilities: Progressive Die Stamping and Beyond

At the heart of Dian Stamping's manufacturing capabilities lies progressive die stamping — a high-efficiency process that feeds a metal coil through a series of stations within a single die, producing a finished part with each press stroke. This method is ideal for high-volume production of complex automotive components where dimensional consistency and repeatability are critical.

Beyond progressive dies, the company also designs and builds transfer dies for large and medium-sized parts, as well as tandem (multi-station) dies for sequential forming operations. These capabilities cover a wide range of applications, including body-in-white panels, door systems, seating components, instrument panel structures, fuel-tank and exhaust systems, clutch assemblies, and chassis parts.

Dian Stamping processes a diverse range of materials — high-strength steel (HSS), multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel — making it a versatile partner for both traditional and electric vehicle programs.

Full-Service Offerings: From Tooling to Finished Assemblies

What sets Dian Stamping apart is its vertically integrated service model. The company does not just build dies — it uses them to produce stamped sheet metal parts, and then validates and assembles those parts using its own inspection and welding fixtures.

1. Stamping Dies

Precision progressive, transfer, and tandem tooling for complex automotive and industrial parts. Typical delivery is 30–40 days for steel stamping dies and approximately 70 days for casting dies, depending on project complexity.

2. Sheet Metal Parts

High-volume stamping and fabrication of custom metal parts, including laser cutting, bending, forming, and welding assemblies. Dian Stamping serves both automotive and household-appliance industries with cost-efficient, scalable production.

3. Checking Fixtures

GD&T-oriented inspection fixtures designed to verify that stamped components and assemblies meet dimensional specifications. These fixtures enable rapid, repeatable quality checks on the production floor, eliminating measurement variability.

4. Welding Jigs and Assembly

Custom welding fixtures and assembly services for accurate, repeatable positioning during welding operations. This includes spot welding, MIG/TIG welding, and sub-assembly integration.

Quality Systems and Certifications

Dian Stamping operates under an ISO 9001 quality management system and follows IATF 16949-oriented automotive manufacturing practices. The company's quality assurance process includes in-line inspections, CMM (coordinate measuring machine) verification, and 3D scanning for dimensional analysis. Prototype services are available for new vehicle programs, and customization can be developed from 2D drawings, 3D CAD data, or physical samples.

Free metal samples may be offered for evaluation (with freight paid by the customer), allowing potential partners to assess quality before committing to production volumes.

Why Global OEMs Choose Dian Stamping

The Cost Advantage of a China-Based Stamping Partner

For global procurement teams seeking automotive stamping dies, China remains the most cost-effective sourcing destination without compromising on quality. Dian Stamping's location in Taizhou, Zhejiang — a region with a deep industrial supply chain for mould and die manufacturing — allows the company to offer competitive pricing while maintaining short lead times. The company's direct factory model means customers pay for manufacturing capability, not layers of brokerage.

Conclusion: A Partner, Not Just a Supplier

In an industry where tooling precision directly impacts vehicle quality and production uptime, the choice of a stamping partner matters. Dian Stamping combines decades of hands-on die-making experience with modern manufacturing scale, all backed by a quality system that meets automotive-grade standards. Whether you need progressive dies for a high-volume program, custom sheet metal parts for a prototype build, or checking fixtures for quality assurance, Dian Stamping delivers — from the first die design to the final assembled part.
