The automotive industry demands more than just a supplier — it demands a manufacturing partner capable of delivering precision tooling, high-volume production, rigorous quality inspection, and reliable assembly support under one roof. For global OEMs and Tier 1 suppliers searching for a dependable stamping die manufacturers, the decision often comes down to who can offer the most integrated solution. Dian Stamping, operating under LINHAI DIAN MOULD CO., LTD, has spent over two decades building exactly that: a complete ecosystem for automotive stamping, tooling, inspection, and welding.

Two Decades of Precision Manufacturing

Established in 2003 in Huangyan, Taizhou, Zhejiang Province, Dian Stamping has grown from a specialized tooling workshop into a comprehensive manufacturing facility covering approximately 50,000 m², including a dedicated die workshop of 4,000 m². With around 110 employees — among them approximately 35 experienced die designers and technicians — the company produces an annual capacity of about 2,000 sets of medium and small stamping dies. This scale, backed by a reported annual die turnover of approximately RMB 50 million, positions Dian Stamping as a serious contender in the global automotive tooling supply chain.

The company's customer roster speaks to its capability: it has supplied tooling and parts to OEMs including KIA, BYD, Toyota, Honda, Suzuki, and Geely, with exports reaching more than 10 countries worldwide.

A Full Spectrum of Automotive Stamping Dies and Tooling

At the core of Dian Stamping's offering is its comprehensive die manufacturing capability. The company produces a wide range of tooling types to meet diverse production needs:

• ● Progressive dies for high-volume, multi-operation stamping
• ● Transfer dies for complex, large-sized parts
• ● Tandem / multi-station dies for flexible production lines
• ● Compound dies for combined operations

These dies are applied across critical automotive systems including body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems. The company processes a wide range of materials including multiphase steel, aluminum, custom rolled and welded plate, and stainless steel — ensuring compatibility with the evolving material requirements of modern vehicle design.

Beyond Tooling: Stamped Parts, Inspection Fixtures, and Welding Jigs

What sets Dian Stamping apart from many stamping die manufacturers is its ability to deliver a complete, end-to-end solution that extends well beyond the die itself.

Sheet Metal Parts Production

Dian Stamping's sheet metal division produces automotive and household-appliance stamping components, custom metal parts, and welding assemblies. From body panels and structural brackets to refrigerator components, the company offers stamping, laser cutting, bending, forming, and powder coating under one roof.

Precision Checking Fixtures

Quality assurance is a critical part of the manufacturing process. Dian Stamping designs and builds high-precision checking fixture solutions that enable fast, repeatable inspection of stamped parts and welded assemblies. These GD&T-oriented fixtures eliminate individual measurement variation and ensure that every part meets OEM-specified tolerances before it reaches the assembly line.

Custom Welding Jigs

To support accurate and repeatable production assembly, Dian Stamping also provides custom welding jig solutions. These fixtures ensure consistent positioning, reduce rework, and improve throughput in welding and assembly operations.
