The Challenge of Fragmented Supply Chains

Many automotive OEMs and Tier suppliers face a common pain point: their stamping dies are designed by one company, manufactured by another, and the stamped parts are produced by yet another. This fragmented approach creates communication gaps, extended lead times, and quality inconsistencies. Every handoff introduces risk — dimensional tolerances drift, deadlines slip, and costs escalate.

The solution lies in choosing a vertically integrated partner who owns the entire chain — from die design and fabrication to production stamping and final assembly. This is precisely the model that LINHAI DIAN MOULD CO., LTD (DIAN STAMPING) has perfected over more than two decades of serving global automotive clients.

A Factory-Backed Approach That Delivers Results

DIAN STAMPING operates as a factory-first manufacturer — not a trading company. Established in 2003 in Huangyan, Taizhou, Zhejiang Province, the company has built a modern facility spanning approximately 50,000 m², including a dedicated die workshop of 4,000 m². With around 110 employees — among them 35 experienced die designers and technicians — the company produces approximately 2,000 sets of medium and small stamping dies annually, with an annual die turnover of roughly RMB 50 million.

This scale is not just impressive on paper. It translates into real-world benefits for customers: shorter communication chains, faster design iterations, and unified quality control from the first CAD drawing to the final stamped part.

Comprehensive Capabilities Under One Roof

When you partner with DIAN STAMPING, you gain access to a full spectrum of manufacturing services. The company specializes in progressive die stamping, transfer dies, and tandem dies for complex large and medium-sized parts. Beyond tooling, DIAN STAMPING produces high-precision stamped sheet metal components, checking fixtures, welding jigs, welded assemblies, and final assembly parts.

The company serves a wide range of automotive applications, including body-in-white systems, door systems, seating systems, instrument panels, exhaust systems, chassis systems, fuel tank systems, and clutch systems. Material expertise covers multiphase steel, aluminum, custom rolled and welded plate, and stainless steel — giving engineers the flexibility to choose the right material for each application.

Quality Standards That Meet Global Expectations

Quality is the cornerstone of any automotive supplier relationship. DIAN STAMPING operates under an ISO 9001 quality management system and follows IATF 16949-oriented manufacturing practices, ensuring that every die and component meets the rigorous standards demanded by the automotive industry.

The company's commitment to quality extends beyond certifications. Each checking fixture is designed for rapid, repeatable dimensional verification, and press dies and checking fixtures are delivered as a matched set — eliminating the alignment issues that plague multi-supplier sourcing models. Prototype services are also available, allowing customers to validate designs before committing to full production runs.

Proven Global Track Record

DIAN STAMPING has earned the trust of major automotive OEMs including KIA, BYD, Toyota, Honda, Suzuki, and Geely, and exports its tooling and parts to more than 10 countries worldwide. This global footprint demonstrates the company's ability to meet diverse engineering standards, delivery schedules, and quality expectations across different markets.

The company's custom sheet metal parts and stamping dies are used by automotive manufacturers who demand consistent quality, competitive factory pricing, and reliable supply relationships. Whether you need a prototype run or high-volume production, DIAN STAMPING has the capacity and experience to deliver.

Competitive Lead Times and Factory Pricing

Time-to-market is critical in the automotive industry. DIAN STAMPING typically delivers steel stamping dies within 30–40 days and casting stamping dies in approximately 70 days, depending on project complexity. As a direct factory, the company offers competitive pricing without intermediary markups, and free metal samples are available (freight paid by the customer) to evaluate quality before placing volume orders.

Customization is available from 2D drawings, 3D data, or physical samples — giving procurement teams the flexibility to work with whatever design specifications they have on hand.

A New Facility for Growing Demand

DIAN STAMPING is investing in the future with a planned new 35,000 m² facility featuring advanced press lines and coating capabilities. This expansion will significantly increase production capacity and allow the company to serve even larger-scale automotive programs while maintaining the precision and quality that its customers have come to expect.
