When automotive OEMs and Tier 1 suppliers evaluate a new tooling partner, they look beyond price. They want a manufacturer with proven scale, diverse technical capabilities, rigorous quality systems, and the ability to deliver complete solutions — from die design to finished assemblies. DA Stamping (LinHai DIAN Mould Co., Ltd.) delivers precisely that. With over 20 years of industry experience, a 50,000 m² production campus, and a track record of serving brands like KIA, BYD, Toyota, Honda, and Suzuki, DA Stamping has built a one-stop manufacturing ecosystem that covers every stage of the metal stamping value chain.

A One-Stop Ecosystem Built for Scale

DA Stamping is not a trading company. It is a full-factory manufacturer with integrated in-house capabilities spanning tool and die design, progressive die stamping, sheet metal fabrication, checking fixture construction, welding jig manufacturing, and final assembly. The company's affiliated entities — Linhai Diyao New Technology Co., Ltd. and Taizhou Elay International Trade Co., Ltd. — further strengthen its supply chain and export capabilities.

The facility in Hongguang Industrial, Linhai, Taizhou, Zhejiang Province, covers approximately 50,000 m² today, with a planned 40,000 m² expansion that will introduce new press lines, automated welding lines, and advanced coating lines. This positions DA Stamping for even greater capacity as global demand for precision automotive stamping dies continues to rise.

Four Core Product Pillars

DA Stamping manufactures a full range of stamping dies, including progressive dies, transfer dies, and tandem dies for medium to large complex automotive parts. The die workshop spans approximately 4,000 m² and supports an annual output of roughly 2,000 sets of medium and small stamping dies. With an annual die turnover of approximately RMB 50 million, the company has the engineering depth to handle high-volume OEM programs.

From body-in-white panels to chassis components, DA Stamping produces custom sheet metal parts using advanced stamping, laser cutting, bending, and welding techniques. The company works with multiphase steel, aluminum, custom rolled and welded plate, and stainless steel, offering flexibility across material specifications.

Every stamped part needs to be verified. DA Stamping designs and builds high-precision checking fixture solutions aligned with GD&T standards. These fixtures enable rapid, repeatable inspection of complex geometries, eliminating individual measurement variation and ensuring that every production batch meets OEM specifications.

Custom welding jigs and fixtures are designed to support precise positioning during welding and assembly operations. Whether for robotic welding cells or manual stations, DA Stamping's jig solutions ensure consistent weld quality and dimensional accuracy throughout the production run.

Certified Quality, Globally Recognized

DA Stamping operates under a robust quality management system. The company holds IATF 16949 certification — the global standard for automotive quality management — as well as ISO 9001 and TUV certifications. It has been recognized as a National High-Tech Enterprise and a Zhejiang Provincial Technology-based SME, reflecting its commitment to innovation and continuous improvement.

Material and Application Expertise

DA Stamping's material processing capabilities cover a broad spectrum:

• Multiphase steel — for high-strength structural components
• Aluminum — for lightweight body and chassis parts
• Custom rolled and welded plate — for specialized geometry requirements
• Stainless steel — for corrosion-resistant applications

These materials are formed into components for eight major automotive application areas:

Factory-Direct Pricing with Full Customization

As a factory-direct manufacturer, DA Stamping offers competitive pricing without compromising quality. Customers can submit requirements via 2D drawings, 3D data, or physical samples, and the engineering team will develop a complete tooling and production solution. Prototype services are available for new program validation, and free metal samples can be provided (freight paid by the customer).

Typical lead times are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity. The company's in-house control over every process step — from die design to tryout — eliminates the delays and quality risks of outsourcing.
