In today's automotive supply chain, the difference between a smooth production ramp and costly downtime often comes down to one thing: the quality of your tooling. Whether you are sourcing progressive die stamping solutions for high-volume body-in-white components or precision automotive stamping dies for complex structural parts, choosing the right manufacturing partner is a strategic decision that affects cost, lead time, and final part quality.
Located in Huangyan, Taizhou — the heart of Zhejiang Province's manufacturing corridor — LINHAI DIAN MOULD CO., LTD (DA Stamping) has been building that trust since 2003. The company operates as a factory-direct supplier, not a trading intermediary, which means its customers enjoy transparent pricing, direct engineering communication, and full control over the production process from die design to tryout.
Manufacturing Scale and Engineering Depth
DA Stamping's facility covers approximately 50,000 square meters, with a dedicated die workshop of 4,000 m². The company employs around 110 people, including roughly 35 die designers and technicians — a ratio that reflects a genuine commitment to in-house engineering capability rather than pure assembly. With an annual output of about 2,000 sets of medium and small stamping dies and a reported annual die turnover of approximately RMB 50 million, the company operates at a scale that can handle both serial production programs and custom one-off tooling projects.

A new 35,000 m² facility is also in the pipeline, featuring additional press lines and coating capabilities, reflecting the company's continued investment in production capacity and surface-treatment quality.
Core Product Portfolio
DA Stamping's product lineup covers the full spectrum of stamping tooling and fabricated metal parts, organized into four main categories:
- Stamping Dies — Progressive, transfer, and tandem dies for large and medium-sized complex automotive parts. The company's die portfolio includes body-in-white components, door system parts, seating system stampings, instrument panel structures, and chassis components.
- Sheet Metal Parts — Custom stamping and fabrication for automotive and household-appliance applications. Capabilities include laser cutting, bending, forming, and powder coating, with materials ranging from high-strength steel and aluminum to stainless steel and galvanized sheet.
- Checking Fixtures — High-precision, GD&T-oriented inspection fixtures that verify dimensional conformity of stamped parts and welded assemblies. As the company's own literature states, "Press dies and checking fixtures are necessary as a set" — a philosophy that supports integrated quality assurance from the toolroom to the production floor.
- Welding Jigs — Custom fixtures designed for accurate, repeatable welding and assembly operations, supporting both manual and robotic welding processes.
Materials processed include multiphase steel (HSS/AHSS), aluminum, custom rolled and welded plate, and stainless steel. This material versatility allows DA Stamping to serve a wide range of application areas, including body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems.
Quality Systems and OEM Track Record
DA Stamping operates under an ISO 9001-certified quality management system, with manufacturing practices aligned to IATF 16949 standards for automotive production. The company's customer list includes major OEMs such as KIA, BYD, Toyota, Honda, Suzuki, and Geely, with exports reaching more than 10 countries worldwide.
For dimensional verification, DA Stamping designs and manufactures checking fixture solutions that enable fast, repeatable inspection of complex geometries — eliminating the individual measurement variation that can arise with manual tools. This is especially valuable for high-volume production runs where every part must meet print specifications without exception.
Quality at a Glance
ISO 9001 certified · IATF 16949-oriented practices · OEM customers include KIA, BYD, Toyota, Honda, Suzuki, Geely · Exported to 10+ countries · Free metal samples available (freight paid by customer) · Prototype services offered from 2D drawings, 3D data, or physical samples.
Lead Times and Commercial Flexibility
In the tooling industry, lead time is often as critical as price. DA Stamping offers competitive delivery schedules: approximately 30–40 days for steel stamping dies and around 70 days for casting stamping dies, subject to project complexity and current workload. The company positions itself as a factory-direct supplier, which eliminates the margins and communication overhead of trading companies and allows for more responsive project management.
Customization is available from 2D drawings, 3D CAD data, or physical samples. The company's engineering team can provide design-for-manufacturing (DFM) feedback early in the quoting phase, helping customers optimize part geometry for cost-effective stamping before steel is ever cut.
