With over two decades of expertise, a 50,000 m² manufacturing campus, and a client roster that includes KIA, BYD, Toyota, and Honda, this Chinese die specialist delivers end-to-end stamped solutions at factory-direct pricing.
In the automotive supply chain, the gap between a stamped part concept and a production-ready component can make or break a vehicle program. Every OEM and Tier-1 supplier needs a partner who can design precision tooling, produce complex sheet metal parts at scale, and maintain rigorous quality standards — all while keeping lead times and costs under control. For more than twenty years, stamping die manufacturers like LINHAI DIAN MOULD CO., LTD have been delivering exactly that, combining deep engineering know-how with a vertically integrated manufacturing footprint in Taizhou, Zhejiang Province, China.
A Manufacturing Powerhouse Built Over Two Decades
Established in 2003, DIAN STAMPING has grown from a specialized tooling workshop into a full-scale production facility. The company's main campus spans approximately 50,000 m², with a dedicated die workshop of 4,000 m². Around 110 employees work across design, tooling, stamping, welding, and quality assurance, including roughly 35 experienced die designers and technicians.
At a Glance
Established 2003 | 50,000 m² Campus | 110+ Employees | 2,000 Die Sets/Year | 50M RMB Annual Die Turnover
The company's annual production capacity reaches approximately 2,000 sets of medium and small stamping dies, with a reported annual die turnover of around RMB 50 million. A planned 35,000 m² expansion will add new press lines and coating capabilities, further strengthening its ability to serve high-volume automotive programs.
Comprehensive Die Engineering: Progressive, Transfer, and Tandem
DIAN STAMPING's core strength lies in its ability to design and build a wide spectrum of tooling. The company produces automotive stamping dies in three principal configurations:
- Progressive Dies — Ideal for high-volume, complex parts requiring multiple forming operations in a single press stroke, commonly used for body-in-white and chassis components.
- Transfer Dies — Designed for larger, deeper-drawn parts where the workpiece moves between independent stations, offering flexibility for medium-to-high production runs.
- Tandem / Multi-Station Dies — A cost-effective solution for mid-volume production, where several press operations are sequenced across multiple machines.
The die shop is equipped to handle multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel — materials increasingly demanded by modern vehicle architectures that prioritize weight reduction and crash performance.
Beyond Dies: A One-Stop Stamping Ecosystem
What sets DIAN STAMPING apart from many tooling-focused suppliers is its ability to deliver the full production chain — from raw material to finished, assembled components. The company's product and service portfolio spans four interconnected categories:
1. Stamping Dies
Precision progressive, transfer, and tandem stamping tooling for complex automotive and industrial parts, covering body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems.
2. Sheet Metal Parts
High-volume production of stamped metal components for both automotive and household appliance industries. The company produces brackets, panels, hinges, structural reinforcements, and other custom sheet metal parts with capabilities that include progressive stamping, deep drawing, forming, laser cutting, and secondary operations such as welding and coating.
3. Checking Fixtures
High-precision, GD&T-oriented inspection fixtures that verify whether stamped components meet dimensional specifications. Each checking fixture is designed to allow rapid, repeatable inspection of large part volumes — eliminating measurement variability and ensuring that every production batch aligns with OEM requirements. Press dies and checking fixtures go hand in hand, and DIAN STAMPING supplies them as integrated sets.
4. Welding Jigs
Custom-designed positioning fixtures for accurate, repeatable welding and assembly. From spot welding and MIG/TIG to robotic welding lines, the company's welding jig solutions help automotive manufacturers achieve consistent weld quality and dimensional accuracy in high-volume production environments.
Quality Standards That Automotive OEMs Trust
DIAN STAMPING operates under a quality management system certified to ISO 9001, with manufacturing practices aligned to IATF 16949 automotive standards. The company implements rigorous in-process inspections, dimensional verification using CMM and 3D scanning, and systematic SPC (Statistical Process Control) throughout its production lines.
Fast Fact: Typical delivery for steel stamping dies is 30–40 days, while casting dies require approximately 70 days — timelines that are competitive even by global standards. Prototype services are available, and the company accepts 2D drawings, 3D data, or physical samples for custom project evaluation.
Global Reach: Serving OEMs Across More Than 10 Countries
DIAN STAMPING's customer base reads like a who's who of global automotive: KIA, BYD, Toyota, Honda, Suzuki, and Geely. The company exports to more than 10 countries, supplying both stamping dies and production parts to OEMs and Tier suppliers worldwide. As a factory-direct manufacturer — not a trading company — DIAN STAMPING offers competitive pricing and direct technical communication with the engineering team responsible for tool design and production.
The company's application expertise spans a wide range of automotive systems, including body-in-white structures, door mechanisms, seating assemblies, instrument panel supports, fuel tank components, exhaust heat shields, clutch system parts, and chassis sub-assemblies. This breadth of experience makes DIAN STAMPING a versatile partner for both new vehicle programs and aftermarket part production.
