How a 20-year-old Chinese manufacturer delivers precision stamping dies, sheet metal parts, checking fixtures, and welding jigs under one roof — at factory-direct pricing.

In the competitive world of automotive manufacturing, finding a supplier that can handle everything from tool design to final assembly is rare. Most OEMs and Tier-1 suppliers juggle multiple vendors for stamping dies, sheet metal parts, inspection fixtures, and welding jigs — a fragmented approach that adds cost, complexity, and lead time.

LINHAI DIAN MOULD CO., LTD (DA Stamping) offers a different model. Based in Taizhou, Zhejiang Province, the company has been a dedicated stamping die manufacturers since 2003, evolving into a fully integrated manufacturing partner. With a 50,000 m² facility, roughly 110 employees including 35 die designers, and an annual capacity of about 2,000 sets of medium and small stamping dies, DA Stamping delivers the scale and expertise that global automotive brands demand.

One Roof, Four Capabilities

What sets DA Stamping apart is its end-to-end service model. The company's capabilities span four interconnected areas, each critical to the automotive supply chain:

This vertical integration means that when you work with DA Stamping, you receive a fully coordinated solution rather than stitching together outputs from separate suppliers. The die design team, stamping production line, fixture workshop, and welding assembly station all operate under a single management system.

Progressive Die Stamping: Precision at Volume

At the heart of DA Stamping's production capability is progressive die stamping. In this process, a coil of sheet metal feeds through a series of die stations, each performing a sequential operation — cutting, bending, drawing, punching, and forming — until a finished part exits the final station. The result is high-speed, high-volume production with exceptional dimensional consistency.

DA Stamping applies progressive die technology across a wide range of automotive applications: body-in-white panels, door hinge reinforcements, seat support beams, floor cross members, heat shields, and instrument panel components. The company also processes advanced materials including multiphase steel and high-strength aluminum alloys, meeting the lightweighting demands of modern vehicle platforms.

For parts requiring more complex geometries, DA Stamping also offers transfer dies and tandem/multi-station dies, giving engineers the flexibility to choose the most cost-effective forming strategy for each part.

Global OEM Trust

DA Stamping's customer list reads like a who's who of global automotive: KIA, BYD, Toyota, Honda, Suzuki, and Geely. These OEMs rely on DA Stamping for automotive stamping dies and stamped components that meet stringent quality and safety standards.

With exports to more than 10 countries, the company has demonstrated its ability to deliver at the quality levels demanded by international automotive markets. Its quality management system is ISO 9001 certified, and the company follows IATF 16949-oriented manufacturing practices to ensure process control and traceability.

Quality Assurance Built In

In automotive stamping, quality is non-negotiable. DA Stamping integrates inspection into every stage of production. Checking fixture technology plays a central role here: custom-designed fixtures allow operators to verify part dimensions quickly and repeatedly, eliminating the individual measurement variation that can occur with manual tools.

The company also offers prototype services, enabling customers to validate die designs and part geometries before committing to full production runs. For steel stamping dies, typical delivery is 30–40 days; for casting stamping dies, approximately 70 days — timelines that reflect the company's commitment to responsive, customer-focused project management.

Welding and Assembly: The Final Link

Beyond stamping, DA Stamping provides complete welding and assembly services. Custom welding jig solutions ensure that stamped components are positioned and welded with precision, producing assembly-ready parts that reduce downstream rework for OEM customers.

From welding jigs and checking fixtures to finished welded assemblies, the company's scope of work means customers can receive fully integrated sub-assemblies rather than individual loose parts. This reduces supply chain complexity, inventory costs, and quality risk.

Factory-Direct: The Cost Advantage

DA Stamping operates as a factory, not a trading company. This distinction matters. By controlling every step from raw material procurement to die design, stamping, and assembly, the company eliminates intermediary markups and delivers factory-direct pricing to its customers.

Customization is available from 2D drawings, 3D data, or physical samples. The company's engineering team works closely with customers to optimize part designs for manufacturability, reducing tooling costs and cycle times.
