When sourcing critical tooling and stamped components for vehicle production, automotive OEMs and Tier 1 suppliers demand more than just competitive pricing. They need a manufacturing partner with proven engineering depth, rigorous quality systems, scalable production capacity, and a track record of delivering complex projects on time. Dian Stamping (LINHAI DIAN MOULD CO., LTD), based in Taizhou, Zhejiang, China, has been that partner for leading automotive brands since 2003 — supplying precision automotive stamping dies, stamped sheet metal parts, checking fixtures, and welding jigs to customers in more than 10 countries worldwide.

A Manufacturing Partner with Proven Scale and Capability

Unlike many trading companies that broker manufacturing services, Dian Stamping is a factory-first operation. The company operates a modern facility covering approximately 50,000 m², including a dedicated die workshop of 4,000 m². With around 110 employees — of whom approximately 35 are die designers and technicians — the company possesses the in-house engineering resources to handle complex tooling projects from concept to tryout. A planned new 35,000 m² facility featuring additional press lines and coating capabilities will further expand capacity in the near future.

Comprehensive Die Solutions: Progressive, Transfer, and Tandem Dies

Dian Stamping specializes in the design and manufacture of all major stamping die types. Whether your project requires high-speed progressive die stamping for complex small-to-medium parts, transfer dies for large automotive panels, or tandem/multi-station dies for multi-step forming sequences, the company's engineering team has the expertise to deliver. The dies are built to handle a wide range of materials, including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel — covering the material diversity that modern automotive body-in-white, chassis, and powertrain applications demand.

As experienced stamping die manufacturers, Dian Stamping supports the full die development lifecycle: from 2D drawings and 3D CAD data to complete tool fabrication, tryout, and sample production. Typical lead times are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity.

Beyond Dies: Sheet Metal Parts, Checking Fixtures, and Welding Jigs

What sets Dian Stamping apart from many die-only suppliers is its ability to deliver a complete manufacturing solution under one roof. Beyond tooling, the company produces custom sheet metal parts for automotive and household appliance applications, including brackets, panels, reinforcements, and structural assemblies. These parts are manufactured using progressive and transfer stamping techniques, with secondary operations such as laser cutting, bending, welding, and surface coating available in-house.

The company also designs and builds checking fixtures for dimensional verification of stamped components — a critical requirement for GD&T-compliant automotive quality assurance. Additionally, custom welding jigs are available to support accurate, repeatable assembly operations. This one-stop capability reduces supply chain complexity, shortens lead times, and simplifies quality management for OEM buyers.

Application Expertise Across Vehicle Systems

Dian Stamping's portfolio of delivered tooling and parts spans virtually every major automotive system. The company has produced stamping dies and components for:

• Body-in-White: Side frames, rear outer panels, A-pillar inner panels, spare tire wells, and structural reinforcements
• Door Systems: Hinge reinforcement plates, door panels, guides, and water-cut reinforcement panels
• Seating Systems: Seat basins, support beams, B-pillar liners, flow channels, and frame assemblies
• Instrument Panels: Dashboard support structures and cross-car beams
• Exhaust & Fuel Systems: Heat shields, shields for thermal protection, and fuel-tank system components
• Chassis Systems: Swing arms, control arms, suspension brackets, and steering components

Quality Systems and OEM Partnerships

Dian Stamping operates under a quality management system aligned with ISO 9001 standards, with manufacturing practices oriented toward IATF 16949 requirements. The company's customer roster includes global automotive OEMs such as KIA, BYD, Toyota, Honda, Suzuki, and Geely — a testament to the consistent quality and delivery performance that the team has sustained over two decades. Rigorous in-process inspections, sample validation, and final quality checks ensure that every die and stamped part meets the tight tolerances and durability standards that automotive production demands.

Factory-Direct Pricing and Global Delivery

As a direct manufacturer without intermediary markups, Dian Stamping offers factory-competitive pricing that typically delivers significant cost advantages compared to Western and other high-cost-region suppliers. The company's export experience spanning more than 10 countries means that international shipping, customs documentation, and communication are handled smoothly. Free metal samples are available upon request (freight paid by the customer), and the engineering team provides responsive support throughout the quotation, design, and production phases.
