In today's automotive supply chain, finding a manufacturing partner who can deliver precision tooling, high-volume stamped parts, and reliable inspection fixtures under one roof is rare. Dian Stamping — the manufacturing division of Linhai Dian Mould Co., Ltd — has been solving exactly that challenge for global OEMs and Tier suppliers since 2003.

Over Two Decades of Die and Stamping Excellence

Established in 2003 in Huangyan, Taizhou, Zhejiang Province, Dian Stamping has grown from a specialized die workshop into a comprehensive manufacturing facility. The company operates a modern 50,000 m² plant with a dedicated 4,000 m² die workshop, staffed by approximately 110 experienced professionals, including 35 die designers and technicians. This scale enables an annual production capacity of roughly 2,000 sets of medium and small stamping dies, with an annual die turnover of approximately RMB 50 million.

The company's core expertise lies in designing and building automotive stamping dies — including progressive dies, transfer dies, and tandem/multi-station dies — for complex body-in-white, door system, seating system, and chassis components. Materials processed range from multiphase steel and aluminum to custom rolled and welded plate and stainless steel, ensuring compatibility with the full spectrum of modern automotive manufacturing requirements.

Beyond Dies: A One-Stop Manufacturing Solution

What sets Dian Stamping apart is its ability to deliver not just tooling but the entire production chain — from die design and fabrication to high-volume sheet metal stamping, welding assembly, and quality inspection. This end-to-end integration eliminates the coordination headaches and cost markups that come with managing multiple suppliers.

For quality assurance, the company supplies precision checking fixture solutions. These GD&T-oriented inspection fixtures allow rapid, repeatable verification of stamped components and assemblies, ensuring every part meets OEM dimensional specifications before moving to the next production stage. In an industry where a single out-of-tolerance part can halt an entire assembly line, having reliable checking fixtures is not optional — it is essential.

Similarly, the company's custom welding jig capabilities support accurate, repeatable positioning during welding and assembly operations. Whether for body-in-white sub-assemblies, chassis components, or seating systems, these jigs ensure consistent weld quality and dimensional accuracy across production runs.

Trusted by Global Automotive Leaders

Dian Stamping's reputation is built on long-term partnerships with some of the world's most demanding automotive brands. The company's customer roster includes KIA, BYD, Toyota, Honda, Suzuki, and Geely, among others. With exports reaching more than 10 countries, Dian Stamping has demonstrated its ability to meet international quality standards and delivery timelines consistently.

Factory-Direct Pricing Without Compromising Quality

As a factory rather than a trading company, Dian Stamping offers direct pricing that typically undercuts Western suppliers by a significant margin. Customers can submit requirements in the form of 2D drawings, 3D data, or physical samples, and the engineering team will handle the rest — from die design and simulation to tryout and mass production. Prototype services are also available for new product development programs.

The company's quality management system follows ISO 9001 standards, with manufacturing practices aligned to IATF 16949 requirements for the automotive sector. This dual focus on cost efficiency and quality assurance is what makes Dian Stamping a preferred partner for both volume production runs and custom, low-volume tooling projects.

Wide Application Coverage Across Vehicle Systems

Dian Stamping's tooling and parts serve a broad range of automotive applications, including:

• Body-in-White: A-pillar panels, side frames, rear outer panels, spare tire wells
• Door Systems: Hinge reinforcement plates, water-cut reinforcement panels, guides
• Seating Systems: Seat basins, support beams, B-pillar liners, battery cases
• Instrument Panels: Dashboard support structures and cross-car beams
• Exhaust & Chassis: Heat shields, swing arms, control arms, floor panels

Beyond automotive, the company also serves the household appliance industry with precision stamped components for refrigerators, washing machines, and ovens, demonstrating versatility across industrial sectors.
