In the world of modern manufacturing, producing high-quality complex sheet metal parts is no small feat. It requires precision engineering, advanced tooling, rigorous quality control, and years of hands-on experience. For automotive OEMs and Tier suppliers seeking a reliable partner, the choice of manufacturer can make or break a production timeline. This is where DIAN STAMPING (LinHai Dian Mould Co., Ltd.) stands apart — a China-based manufacturer with more than 20 years of industry heritage, a 50,000 m² modern facility, and a comprehensive suite of capabilities that spans stamping dies, sheet metal parts, checking fixtures, and welding jigs.
A One-Stop Manufacturing Partner for the Automotive Industry
Established in 2003 in Huangyan, Taizhou, Zhejiang Province, DIAN STAMPING has grown from a specialized tooling workshop into a full-service manufacturing partner. The company's core strength lies in its ability to deliver end-to-end solutions — from die design and prototyping to high-volume stamping, welding, and assembly. Unlike many suppliers that focus on a single link in the supply chain, DIAN offers a vertically integrated approach that reduces lead times, simplifies communication, and ensures consistent quality across every stage of production.
The company's client roster speaks to its capabilities: KIA, BYD, Toyota, Honda, Suzuki, and Geely are among the OEMs that trust DIAN for their tooling and stamped components. With exports reaching more than 10 countries, DIAN STAMPING has established itself as a globally recognized name among stamping die manufacturers.
Manufacturing Scale and Technical Capabilities
DIAN's manufacturing infrastructure is built for precision and volume. The facility spans 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 combines deep engineering talent with modern production equipment to deliver exceptional results.
Key capacity highlights:
- Annual production capacity of approximately 2,000 sets of medium and small stamping dies
- Annual die turnover of approximately RMB 50 million
- A planned new 35,000 m² facility featuring advanced press and coating lines
- Materials processed: multiphase steel, aluminum, custom rolled and welded plate, and stainless steel
- Die types: progressive dies, transfer dies, and tandem/multi-station dies
When it comes to automotive stamping dies, DIAN's expertise covers body-in-white components, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems. This breadth of application knowledge means that whether a customer needs a simple bracket or a complex structural reinforcement panel, DIAN has the engineering know-how to deliver.
Beyond Stamping: Integrated Services for Complete Solutions
Sheet Metal Parts
DIAN's sheet metal division produces custom stamped parts not only for automotive applications but also for the household appliance industry. The company's capabilities include progressive and transfer stamping, deep drawing and forming, custom tool and die design, and high-volume production with material options spanning stainless steel, aluminum, cold-rolled steel, and galvanized steel. This versatility makes DIAN a preferred supplier for manufacturers of refrigerators, washing machines, ovens, and other home appliances.
Checking Fixtures
Quality assurance is a cornerstone of DIAN's operations. The company designs and manufactures high-precision checking fixtures that enable rapid, repeatable inspection of stamped components. These fixtures are essential for eliminating measurement variability and ensuring that every part meets GD&T specifications before it moves to the next stage of assembly.
Welding Jigs
To support accurate and repeatable welding operations, DIAN provides custom welding jigs and fixtures. These tools are engineered to position components precisely during welding, reducing distortion and ensuring consistent weld quality across production runs. The company's welding jig service extends from design through fabrication and on-site support.
Quality Systems and Certifications
DIAN STAMPING operates under a quality management system aligned with ISO 9001 standards, with manufacturing practices oriented toward IATF 16949 automotive requirements. The company offers customization from 2D drawings, 3D data, or physical samples, and provides prototype services to validate designs before full-scale production. Typical delivery timelines are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, subject to project scope.
