In the automotive industry, the quality of every stamped component begins with the tooling behind it. Whether you are sourcing stamping die manufacturers for a new vehicle program or looking for a long-term partner who can handle complex sheet metal parts, checking fixtures, and welding jigs under one roof, the choice of supplier directly impacts your production timeline, part quality, and total cost.
As global automotive supply chains increasingly look to China for competitive pricing without compromising on quality, LINHAI DIAN MOULD CO., LTD — widely known as Dian Stamping — has established itself as a reliable, factory-direct partner for OEMs and Tier-1 suppliers worldwide. Here is an in-depth look at what makes Dian Stamping a standout choice among automotive stamping dies manufacturers.
Company Overview: Built on Two Decades of Expertise
Founded in 2003 and headquartered in Huangyan, Taizhou, Zhejiang Province — a region renowned for its模具 (mold-making) industrial cluster — Dian Stamping has spent more than 20 years perfecting the art and science of metal stamping. The company's modern facility covers approximately 50,000 m², with a dedicated die workshop of 4,000 m², and employs around 110 people, including approximately 35 experienced die designers and technicians.

Global Export Reach
The company's annual die turnover of approximately RMB 50 million reflects not only its production scale but also the trust placed by well-known automotive brands. Dian Stamping's customer roster includes global OEMs such as KIA, BYD, Toyota, Honda, Suzuki, and Geely — a track record that speaks to consistent quality and on-time delivery.
Comprehensive Product & Service Portfolio
Unlike many suppliers who specialize in only one segment of the stamping process, Dian Stamping offers a true one-stop solution spanning four core areas:
1. Stamping Dies
The company designs and manufactures progressive dies, transfer dies, and tandem/multi-station dies for large and medium-sized complex automotive parts. These precision tooling solutions are used across body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems. With capabilities in processing multiphase steel, aluminum, custom rolled and welded plate, and stainless steel, Dian Stamping's dies meet the demanding requirements of modern automotive manufacturing.
2. Sheet Metal Parts
Beyond tooling, Dian Stamping produces high-quality stamped sheet metal parts and welding assemblies for both automotive and household appliance industries. From custom brackets and panels to structural components, the company offers end-to-end service from prototyping to high-volume production.
3. Checking Fixtures
Quality assurance is only as good as the measurement tools used. Dian Stamping provides high-precision, GD&T-oriented checking fixture solutions that enable fast, repeatable inspection of stamped components and assemblies. A checking fixture allows manufacturers to verify large numbers of parts quickly and eliminates individual measurement variation — essential for maintaining tight tolerances in high-volume production.
4. Welding Jigs
To support downstream assembly operations, Dian Stamping also supplies custom welding jigs designed for accurate, repeatable positioning during welding and assembly. These fixtures ensure consistent weld quality and dimensional accuracy in production environments.
Key Application Areas: Body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems.
Quality and Certifications
Dian Stamping operates under a quality management system certified to ISO 9001, and the company's manufacturing and quality practices are oriented toward IATF 16949 standards — the global technical specification for automotive industry quality management. This commitment to quality is embedded in every stage of production, from die design and material selection to tryout, inspection, and final delivery.
As a factory-direct manufacturer (not a trading company), Dian Stamping offers full traceability and direct communication with the engineering team. Customization is available from 2D drawings, 3D data, or physical samples, and prototype services are offered to help customers validate designs before committing to mass production.
Delivery and Lead Times
In the fast-paced automotive industry, delivery reliability is as important as product quality. Dian Stamping's typical lead times are:
- Steel stamping dies: 30–40 days, subject to project complexity
- Casting stamping dies: Approximately 70 days
- Free metal samples available upon request (freight paid by customer)

Looking Ahead: Investment in Growth
Dian Stamping is not resting on its track record. The company is investing in a new 35,000 m² facility featuring advanced press lines and coating lines, which will significantly expand production capacity and enable the company to serve larger, more complex projects. This expansion reflects the company's commitment to growing alongside its global customers as the automotive industry transitions toward electrification, lightweight materials, and higher-volume production.
