In the competitive world of automotive manufacturing, the quality of your tooling determines the quality of your production. For OEMs and Tier 1 suppliers seeking reliable automotive stamping dies, the choice of manufacturing partner is one of the most critical decisions in the supply chain. DIAN STAMPING (LINHAI DIAN MOULD CO., LTD) has built a reputation over two decades as a precision-driven, cost-effective partner for global automotive brands.

Two Decades of Die-Making Expertise

Established in 2003 in Huangyan, Taizhou, Zhejiang Province, DIAN STAMPING brings more than 20 years of hands-on experience in the design and manufacture of precision stamping tooling. The company serves some of the world's most recognized automotive names, including KIA, BYD, Toyota, Honda, Suzuki, and Geely, with exports reaching more than 10 countries. This depth of experience is not merely a number — it represents thousands of die projects delivered, each with its own set of engineering challenges solved through practical know-how and continuous improvement.

Scale That Matches Global Demand

One of the most common challenges automotive buyers face when sourcing from stamping die manufacturers is capacity. Can the supplier handle high-volume production without compromising quality? DIAN STAMPING answers this question with a modern facility covering approximately 50,000 m², including a dedicated die workshop of 4,000 m². With around 110 employees — including 35 die designers and technicians — the company maintains an annual capacity of about 2,000 sets of medium and small stamping dies.

A new 35,000 m² facility is also in development, featuring new press lines and coating capabilities, signaling the company's commitment to scaling alongside its customers' growing needs.

Comprehensive Die Technology Portfolio

DIAN STAMPING's technical capabilities span the full spectrum of stamping die technologies. The company specializes in progressive die stamping, transfer dies, and tandem/multi-station dies, covering everything from large body panels to intricate structural components. These dies support a wide range of automotive applications, including body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems.

Material versatility is another strength. The team works with multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel — ensuring that the right material is matched to the right application for optimal performance and cost efficiency.

Beyond Dies: A One-Stop Manufacturing Partner

What sets DIAN STAMPING apart from many competitors is its ability to deliver more than just stamping dies. The company offers a complete ecosystem of manufacturing services:

• Stamped Sheet Metal Parts — High-volume production of automotive and household-appliance stampings, with custom fabrication and welding assemblies.
• Checking Fixtures — Precision inspection fixtures designed to GD&T standards, ensuring every stamped part meets dimensional specifications before it reaches the assembly line.
• Welding Jigs — Custom fixtures for accurate, repeatable welding and assembly operations, reducing cycle times and improving quality consistency.

This vertically integrated approach means customers can source tooling, production parts, and quality inspection fixtures from a single, accountable partner — reducing lead times, simplifying logistics, and eliminating the coordination headaches of managing multiple suppliers.

Quality Systems and Customization

DIAN STAMPING operates under an ISO 9001 quality management system, with manufacturing practices aligned to IATF 16949 standards for automotive production. The company is a factory-direct supplier — not a trading company — which means customers benefit from transparent pricing and direct communication with the engineering team.

Customization is a core service. The team can work from 2D drawings, 3D data, or even physical samples to develop tooling that meets exact specifications. Prototype services are available for new product development, and free metal samples can be provided (with freight paid by the customer). Typical delivery timelines are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity.

Why Global OEMs Choose DIAN STAMPING

The automotive industry demands suppliers who can deliver precision at scale, maintain consistent quality across thousands of parts, and respond with agility to changing production schedules. DIAN STAMPING's combination of experienced engineering talent, substantial manufacturing capacity, and end-to-end service capabilities makes it a compelling choice for OEMs looking to optimize their supply chain.

Whether you are launching a new vehicle program, seeking a secondary source for critical stamping dies, or looking to consolidate your tooling supply base, DIAN STAMPING offers the technical depth and production capacity to support your goals.
