The Foundation of Precision — Stamping Die Expertise

For over 20 years, DIAN STAMPING (LinHai Dian Mould Co., Ltd.) has been at the forefront of precision die manufacturing. Established in 2003 in Huangyan, Taizhou, Zhejiang Province, the company has grown into a modern manufacturing hub spanning approximately 50,000 m². With a dedicated team of around 110 employees — including 35 experienced die designers and technicians — DIAN STAMPING delivers comprehensive automotive stamping dies that meet the most demanding specifications of global automotive brands.

The company's annual capacity of approximately 2,000 sets of medium and small stamping dies, supported by an annual die turnover of around RMB 50 million, demonstrates a production scale that few competitors can match. A planned 35,000 m² facility featuring new press and coating lines will further expand this capacity, positioning DIAN STAMPING for even greater output in the years ahead.

Comprehensive Die Technologies for Complex Automotive Parts

DIAN STAMPING's technical expertise spans the full spectrum of die manufacturing. The company specializes in progressive die stamping, transfer dies, and tandem or multi-station dies — each optimized for specific production requirements. Progressive dies excel at high-volume, multi-operation forming in a single press stroke, while transfer dies handle larger, more complex panels requiring intermediate handling between stations.

This versatility allows DIAN STAMPING to produce parts across virtually every automotive system:

The company processes a wide range of materials including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel — meeting the lightweighting and strength requirements of modern vehicle designs.

Beyond Dies — A Complete Manufacturing Ecosystem

What truly distinguishes DIAN STAMPING is its ability to deliver far more than stamping tooling alone. The company offers four integrated product and service categories that create a seamless end-to-end manufacturing experience:

1. Stamping Dies — Precision progressive, transfer, and tandem dies for complex automotive parts.
2. Sheet Metal Parts — Custom stamped and fabricated metal parts for automotive and household appliance applications, including welded assemblies.
3. Checking Fixture — High-precision, GD&T-oriented inspection fixtures that verify dimensional accuracy of stamped components and assemblies. Every checking fixture is designed to eliminate individual measurement variation and enable rapid, repeatable quality inspection on the production floor.
4. Welding Jig — Custom welding fixtures and positioning tools that ensure accurate, repeatable assembly operations.

This one-stop approach eliminates the coordination overhead of managing multiple suppliers, accelerates time-to-market, and ensures consistent quality across the entire production chain — from raw material to finished assembly.

Quality Systems That Meet Global Standards

Quality is embedded in every stage of DIAN STAMPING's manufacturing process. The company operates under an ISO 9001 quality management system and follows IATF 16949-oriented automotive manufacturing practices. From raw material inspection through CNC machining, die assembly, tryout, and final validation, each step is subject to rigorous quality controls.

The company's engineering team works from 2D drawings, 3D data, or physical samples, offering prototype services and free metal samples (with freight paid by the customer) to validate designs before full-scale production. This commitment to quality and customization has earned DIAN STAMPING the trust of some of the world's most demanding automotive brands.

Serving the World's Leading Automotive Brands

DIAN STAMPING's track record speaks for itself. The company has supplied stamping dies, sheet metal parts, checking fixtures, and welding jigs to automotive OEMs including KIA, BYD, Toyota, Honda, Suzuki, and Geely, and exports to more than 10 countries worldwide. This global customer base reflects the company's ability to consistently meet the quality, delivery, and cost requirements of international automotive programs.

Factory-Direct Pricing and Fast Delivery

As a factory-direct manufacturer — not a trading company — DIAN STAMPING offers competitive pricing without compromising quality. Typical delivery is 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity and requirements. The company's deep engineering bench and integrated production system enable rapid response to urgent tooling needs and engineering changes.

Conclusion: Choose a Partner, Not Just a Supplier

When selecting an automotive stamping dies partner, look beyond the price tag. Consider the depth of engineering experience, the breadth of manufacturing capabilities, the strength of quality systems, and the proven track record of on-time delivery. DIAN STAMPING offers all of this and more — combining decades of hands-on die-making expertise with a modern facility, a comprehensive service portfolio, and a customer-first approach that has earned the trust of leading automotive OEMs worldwide.
