Two Decades of Stamping Excellence

Founded in 2003 and headquartered in Linhai, Taizhou, Zhejiang Province, DIAN STAMPING brings over 20 years of hands-on experience in the design and manufacture of metal stamping dies, precision stamped components, checking fixtures, and welding jigs. Operating from a 50,000 m² modern facility, the company has grown into a one-stop manufacturing partner for the automotive, aerospace, electronics, and home appliance industries.

With a dedicated die workshop spanning 4,000 m², a team of approximately 110 employees — including 35 highly skilled die designers and technicians — and an annual output capacity of 2,000 sets of medium and small stamping dies, DIAN STAMPING possesses the scale and expertise to handle projects of any complexity. The company's annual die turnover of approximately RMB 50 million reflects its established position in the market.

Comprehensive Product Portfolio Under One Roof

What sets DIAN STAMPING apart from many competitors is its ability to offer end-to-end solutions — from tooling design to finished assembly — all under one roof. The company's product and service offerings are organized into four core categories:

• Stamping Dies — Including progressive dies, transfer dies, and tandem/multi-station dies for medium to large complex automotive parts. Each die is engineered using advanced CAD/CAM software and undergoes rigorous testing before delivery.
• Sheet Metal Parts — High-precision stamped components for automotive body-in-white systems, seating systems, door systems, instrument panels, fuel tanks, exhaust systems, clutch systems, and chassis systems. Materials processed include multiphase steel, aluminum alloys, stainless steel, and custom rolled steel.
• Checking Fixtures — GD&T-oriented inspection tooling designed to verify dimensional accuracy of stamped components and welded assemblies, ensuring every part meets OEM specifications.
• Welding Jigs — Custom fixtures and modular tooling systems that enhance repeatability, positioning accuracy, and efficiency in welding and assembly processes.

Beyond these core categories, DIAN STAMPING also offers value-added services including welding processing, powder coating, electrophoresis, and finished product assembly — providing a truly integrated manufacturing experience.

Certified Quality, Global Standards

Quality assurance is deeply embedded in DIAN STAMPING's operations. The company has obtained ISO 9001 and IATF 16949 certifications, and is recognized as a National High-Tech Enterprise in China. These credentials are not merely badges on a wall — they reflect a systematic approach to quality management that spans material sourcing, die design, production, inspection, and delivery.

The company's quality management system includes in-line inspections, CMM (Coordinate Measuring Machine) verification, and dimensional analysis to ensure every stamped component and tooling set meets the tight tolerances demanded by the automotive industry.

A Trusted Partner to Global Automotive Brands

DIAN STAMPING's track record speaks for itself. The company serves customers including KIA, BYD, Toyota, Honda, Suzuki, and Geely, and exports its products to more than 10 countries worldwide. This global client base is a testament to the company's ability to consistently deliver high-quality tooling and stamped parts that meet the rigorous standards of international automotive OEMs.

Whether it's a complex progressive die for a body-in-white component or a high-volume production run of stamped seat brackets, DIAN STAMPING has demonstrated the reliability and technical capability that global manufacturers demand.

Material Versatility and Technical Capability

One of DIAN STAMPING's key strengths is its versatility in material processing. The company's capabilities span:

• Multiphase steel parts — High-strength materials for structural automotive components
• Aluminum parts — Lightweight solutions for fuel efficiency and EV applications
• Custom rolled steel and welded plate parts — Tailored material solutions for specialized applications
• Stainless steel parts — Corrosion-resistant components for exhaust and under-hood applications

This breadth of material expertise means customers can consolidate their sourcing — rather than working with multiple suppliers for different material types, they can rely on DIAN STAMPING as a single, qualified partner.

Factory-Direct Pricing with No Outsourcing

DIAN STAMPING operates as a true factory, not a trading company. Every stage of production — from die design and machining to stamping, welding, coating, and assembly — is handled in-house with no outsourcing. This vertical integration delivers several concrete advantages to customers:

• Cost competitiveness — Factory-direct pricing without middleman markups
• Shorter lead times — Typical delivery of 30–40 days for steel stamping dies and approximately 70 days for casting dies
• Consistent quality — Full control over every production step
• Flexible customization — Support for non-standard OEM/ODM projects from 2D drawings, 3D data, or physical samples
• Free samples and prototyping — DIAN STAMPING offers free tooling and sampling to qualified customers, reducing upfront project risk

Application Areas Across the Vehicle

DIAN STAMPING's components and tooling are used across a wide range of automotive systems:

• Seat Systems — Seat basins, support beams, B-pillar liners, frames
• Body-in-White Systems — Side frames, A-pillar panels, rear outer panels, floor components
• Door Systems — Hinge reinforcement plates, water-cut reinforcement panels, guides
• Dashboard Systems — Instrument panel supports and brackets
• Exhaust Systems — Heat shields and thermal management components
• Fuel Tank Systems — Structural brackets and mounting components
• Chassis Systems — Control arms, swing arms, suspension components
• Clutch Systems — Precision stamped transmission parts
