For automotive OEMs and Tier 1 suppliers, choosing the right tooling partner is one of the most consequential decisions in a vehicle program. The wrong choice means delayed timelines, inconsistent part quality, and costly engineering changes. The right choice delivers precision tooling, reliable production, and a long-term supply partnership that spans multiple vehicle generations.
LINHAI DIAN MOULD CO., LTD 鈥?operating globally as DIAN STAMPING 鈥?has been that right choice for leading automotive brands since 2003. Based in Zhejiang, China, the company has evolved from a specialized die shop into a full-service manufacturing partner offering progressive die stamping, transfer dies, sheet metal fabrication, precision checking fixtures, and custom welding jigs. This article explores why global OEMs continue to trust DIAN STAMPING for their most demanding tooling programs.
Two Decades of Automotive Tooling Expertise
Founded in 2003 in Huangyan, Taizhou, DIAN STAMPING brings more than 20 years of hands-on experience in stamping die manufacturers and precision metal forming. What started as a modest die workshop has grown into a modern manufacturing enterprise with a facility covering approximately 50,000 m虏, including a dedicated die workshop of 4,000 m虏.
The company's engineering team comprises approximately 110 employees, of whom 35 are dedicated die designers and technicians. This depth of in-house engineering talent enables DIAN STAMPING to handle complex tooling projects from concept through tryout, without relying on external design resources.

Comprehensive Product Portfolio
Unlike many tooling suppliers that specialize in only one discipline, DIAN STAMPING offers an integrated suite of products and services that cover the full automotive manufacturing workflow:
| Product Category | Capabilities | Applications |
|---|---|---|
| Stamping Dies | Progressive, transfer, and tandem dies for medium-to-large complex parts | Body-in-white, door systems, chassis, seating |
| Sheet Metal Parts | Custom stamping, laser cutting, bending, welding assemblies | Automotive structural parts, household appliance components |
| Checking Fixtures | GD&T-based precision inspection fixtures for dimensional verification | Stamped parts, welded assemblies, sub-assemblies |
| Welding Jigs | Custom welding fixtures for accurate, repeatable production assembly | Body assemblies, sub-frame welding, exhaust systems |
The company's stamping dies cover progressive dies, transfer dies, and tandem/multi-station dies capable of producing parts for body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems. Annual die production capacity reaches approximately 2,000 sets of medium and small stamping dies.
Material Versatility and Process Capability
Modern automotive manufacturing demands the ability to process a wide range of advanced materials. DIAN STAMPING has invested in the equipment and expertise to handle:
- Multiphase steel (AHSS) 鈥?for lightweight structural components with high crash performance
- Aluminum alloys 鈥?for weight reduction in body panels and EV components
- Custom rolled and welded plate 鈥?for specialized structural applications
- Stainless steel 鈥?for exhaust system components and corrosion-resistant parts
Beyond material processing, DIAN STAMPING offers secondary operations including laser cutting, welding, assembly, and surface finishing 鈥?providing a true one-stop solution that reduces supply chain complexity for OEMs.
Quality Systems and Certifications
Quality assurance is embedded in every stage of DIAN STAMPING's manufacturing process. The company operates an ISO 9001-certified quality management system, and its manufacturing practices are aligned with IATF 16949 automotive standards. This commitment to quality is reflected in the company's customer roster, which includes globally recognized automotive brands such as KIA, BYD, Toyota, Honda, Suzuki, and Geely.
Each checking fixture is designed and built to GD&T standards, enabling precise dimensional verification of stamped components and welded assemblies. This eliminates measurement variability and ensures that every part meets OEM specifications before it leaves the factory.
Factory-Direct Pricing and Rapid Delivery
As a factory-direct manufacturer 鈥?not a trading company 鈥?DIAN STAMPING offers competitive pricing without intermediaries. Typical lead times are 30鈥?0 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity. The company also offers prototyping services and free metal samples (with freight paid by the customer), allowing buyers to evaluate quality before committing to full production.
Customization is available from 2D engineering drawings, 3D CAD data, or physical samples, giving customers flexibility in how they communicate their requirements.
A Trusted Partner for Global Automotive Programs
DIAN STAMPING exports to more than 10 countries and serves a diverse customer base ranging from global automotive OEMs to Tier 1 suppliers and industrial equipment manufacturers. The company's value proposition is straightforward: precision engineering, end-to-end manufacturing capability, factory-direct pricing, and a commitment to long-term supply relationships.
With a planned new 35,000 m虏 facility featuring upgraded press lines and coating capabilities, DIAN STAMPING is positioning itself for the next phase of growth 鈥?supporting the increasing demand for electric vehicle components, lightweight materials processing, and higher-volume production programs.
Whether you need precision stamping dies, high-volume sheet metal parts, custom checking fixtures, or welding jigs, DIAN STAMPING has the engineering expertise and manufacturing capacity to deliver.
