In the competitive world of automotive manufacturing, the quality of your tooling and stamped components directly determines production efficiency, part consistency, and ultimately, your bottom line. Whether you need complex stamping die manufacturers for body-in-white parts, precision sheet metal components, or dedicated inspection and welding fixtures, partnering with an experienced, factory-direct supplier is critical. DA Stamping (LINHAI DIAN MOULD CO., LTD), established in 2003 and headquartered in Taizhou, Zhejiang, China, brings over two decades of hands-on expertise to the global automotive supply chain — delivering precision-engineered tooling and stamped parts that OEMs and Tier-1 suppliers trust.

Who We Are

DA Stamping is a China-based manufacturer that specializes in the full spectrum of automotive stamping tooling and production. Unlike general trading companies, we are a factory — a complete manufacturing facility covering approximately 50,000 m², with a dedicated die workshop of 4,000 m² and a planned 35,000 m² expansion featuring new press and coating lines. Our team of around 110 employees includes approximately 35 experienced die designers and technicians, enabling us to deliver end-to-end solutions from die design and prototyping to high-volume stamping, welding, and assembly.

Our customers include global automotive brands such as KIA, BYD, Toyota, Honda, Suzuki, and Geely, and we export to more than 10 countries worldwide. We hold ISO 9001 certification and operate with IATF 16949-oriented quality practices, ensuring that every die and component we ship meets rigorous automotive-grade standards.

Our Core Capabilities

DA Stamping offers four integrated product and service categories that cover the complete manufacturing lifecycle of automotive metal parts — from tooling design to finished components.

Our Quality Assurance Process

At DA Stamping, quality is not an afterthought — it is built into every stage of production. Our approach mirrors the rigorous standards expected by global automotive manufacturers:

• Engineering Design: Our team of 35+ die designers uses advanced CAD/CAM and simulation tools to optimize die structure, forming stability, and material flow before any steel is cut.
• Precision Machining: We employ CNC machining centers, wire EDM, and surface grinding systems to achieve micron-level accuracy on every die component.
• Material Control: Only certified tool steels (SKD11, DC53, and powder metallurgy grades) are used, with full hardness and batch traceability.
• Heat Treatment: Controlled vacuum hardening, cryogenic treatment, and multi-stage tempering ensure extended die life and dimensional stability.
• Trial Stamping & Inspection: Every die undergoes production trial runs, with CMM inspection, surface roughness measurement, and burr analysis to verify part quality.
• Ongoing Support: We provide technical support throughout the die lifecycle, including maintenance and optimization services.
