With 20+ years of experience, a 50,000 m² manufacturing campus, and a one-stop service model spanning stamping dies, sheet metal parts, checking fixtures, and welding jigs, DIAN STAMPING is redefining what it means to be a true automotive manufacturing partner.
In today's competitive automotive landscape, OEMs and Tier 1 suppliers are under constant pressure to reduce costs, shorten lead times, and maintain uncompromising quality. Choosing the right manufacturing partner is no longer just about finding a supplier — it is about finding a collaborator who can integrate tooling design, stamping production, quality inspection, and assembly services under one roof. This is precisely where DIAN STAMPING stands out.
LINHAI DIAN MOULD CO., LTD (DIAN STAMPING) is a China-based, factory-direct manufacturer specializing in automotive stamping dies, stamped sheet metal parts, checking fixtures, welding jigs, and assembly solutions — serving global customers including KIA, BYD, Toyota, Honda, Suzuki, and Geely.
Company Overview: Built on Two Decades of Excellence
Founded in 2003 in Huangyan, Taizhou — the heart of Zhejiang Province's mold-making industrial cluster — DIAN STAMPING has grown from a specialized die workshop into a comprehensive manufacturing enterprise. The company operates a modern facility covering approximately 50,000 m², with a dedicated die workshop of 4,000 m² and a planned new 35,000 m² facility featuring advanced press and coating lines.
With around 110 employees — including 35 experienced die designers and technicians — DIAN STAMPING achieves an annual production capacity of approximately 2,000 sets of medium and small stamping dies, with an annual die turnover of roughly RMB 50 million. The company exports to more than 10 countries, serving a global customer base that spans Asia, Europe, and the Americas.
Core Capabilities: Precision automotive stamping dies and Beyond
DIAN STAMPING's core competency lies in the design and manufacture of high-precision stamping tooling. The company produces a full spectrum of die types, including progressive dies, transfer dies, and tandem/multi-station dies, capable of handling complex geometries for large and medium-sized parts. Material processing capabilities extend to multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel — meeting the diverse requirements of modern vehicle programs.
The company's progressive die stamping expertise is particularly noteworthy. Progressive dies allow multiple operations — blanking, piercing, forming, and trimming — to be performed in a single press stroke across multiple stations, dramatically improving throughput and reducing per-part cost. This makes DIAN STAMPING an ideal partner for high-volume production runs where consistency and efficiency are paramount.
One-Stop Service: Four Integrated Product Lines
1. Stamping Dies — Precision tooling including progressive, transfer, and tandem dies for BIW (body-in-white), door systems, seating systems, instrument panels, and chassis components. With 65+ product records in this category alone, the company has deep expertise across virtually every automotive subsystem.
2. Sheet Metal Parts — From custom stamping and laser cutting to powder coating and welding assembly, DIAN STAMPING delivers fully fabricated sheet metal components for both automotive and household appliance industries. Material options include stainless steel, aluminum, cold-rolled steel, and galvanized steel.
3. Checking Fixture — High-precision, GD&T-oriented inspection fixtures that enable rapid and accurate dimensional verification of stamped components and welded assemblies. As the company's product page explains, press dies and checking fixtures are always needed as a set — making DIAN STAMPING's combined offering a natural advantage for customers.
4. Welding Jig — Custom welding fixtures designed for accurate, repeatable positioning during arc welding, spot welding, and robotic welding operations. These jigs ensure consistent weld quality and dimensional stability in high-volume production environments.
Quality Assurance and stamping die manufacturers Standards
DIAN STAMPING operates under a quality management system aligned with ISO 9001 standards, with manufacturing practices oriented toward IATF 16949 automotive requirements. The company's quality assurance process covers the entire production chain: from incoming material inspection and in-process dimensional checks to final CMM (coordinate measuring machine) validation and functional testing of dies and fixtures.
The company also offers prototype services, customization from 2D drawings or 3D data, and free metal samples (with freight paid by the customer). Typical delivery times are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, subject to project scope and complexity.
