In the fast-evolving automotive industry, precision metal forming lies at the heart of modern vehicle manufacturing. From body-in-white structures to seating systems, chassis components to battery enclosures, the quality of stamped parts directly impacts crash safety, weight reduction, and assembly efficiency. DIAN STAMPING, operating under LINHAI DIAN MOULD CO., LTD., has served as a reliable manufacturing partner for global automotive OEMs and Tier suppliers since 2003, delivering precision-engineered automotive stamping dies, stamped sheet metal parts, checking fixtures, and welding jigs from its modern facility in Zhejiang, China.

Two Decades of Die and Stamping Excellence

Founded in 2003 and headquartered in Huangyan, Taizhou, DIAN STAMPING has accumulated more than 20 years of hands-on experience in tool and die manufacturing, sheet metal stamping, welding, and assembly. The company operates a purpose-built facility covering approximately 50,000 m², including a dedicated die workshop of 4,000 m², with a planned expansion of an additional 35,000 m² featuring new press lines and advanced coating capabilities.

With a skilled workforce of around 110 employees — including approximately 35 die designers and technicians — DIAN STAMPING maintains an annual capacity of about 2,000 sets of medium and small stamping dies and an annual die turnover of approximately RMB 50 million. This scale positions the company as a robust, mid-to-high-volume manufacturer capable of supporting both prototype development and mass production programs.

Comprehensive Product and Service Portfolio

DIAN STAMPING's capabilities span the full manufacturing spectrum — from die design and fabrication to high-volume stamping, inspection, welding, and assembly. The company's service offering is organized into four core categories:

Stamping Dies

The company specializes in progressive die stamping, transfer dies, and tandem/multi-station dies for complex automotive and industrial parts. These dies are designed to process a wide range of materials including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel — supporting lightweight vehicle design and high-strength structural requirements. With 65 stamped die products archived on the site, the range covers body-in-white panels, door system components, seat structures, instrument panel supports, fuel-tank and exhaust system parts, and chassis components.

Sheet Metal Parts

Beyond die manufacturing, DIAN STAMPING produces high-quality stamped sheet metal parts for automotive and household appliance industries. Capabilities include progressive and transfer stamping, deep drawing, custom tool and die design, laser cutting, bending, welding, and surface coating. Products range from automotive body panels and chassis brackets to refrigerator components and appliance housings, with material options spanning stainless steel, aluminum, cold-rolled steel, and galvanized steel.

Checking Fixtures

Precision inspection is critical in automotive quality assurance. DIAN STAMPING designs and manufactures high-precision checking fixture solutions that enable fast, accurate dimensional verification of stamped components and welded assemblies. These fixtures eliminate measurement variability and ensure that every part conforms to GD&T specifications before moving to the next production stage.

Welding Jigs

Consistent welding quality depends on precise part positioning. DIAN STAMPING offers custom welding jigs designed for accurate, repeatable production and assembly. These fixtures support spot welding, MIG/TIG welding, and robotic welding applications, ensuring dimensional stability and structural integrity across weld assemblies.

Global OEM Partnerships and Export Reach

DIAN STAMPING has earned the trust of leading automotive manufacturers including KIA, BYD, Toyota, Honda, Suzuki, and Geely. The company exports its tooling and stamped parts to more than 10 countries, serving global OEMs and Tier 1 suppliers who demand precision, consistency, and on-time delivery. This international footprint reflects the company's ability to meet diverse engineering standards and quality requirements across markets.

Quality Systems and Manufacturing Capabilities

Quality is embedded in every stage of the production process. DIAN STAMPING operates under an ISO 9001 quality management system and follows IATF 16949-oriented automotive manufacturing practices. The company's quality assurance framework includes in-line inspections, 3D coordinate measuring machine (CMM) verification, and strain analysis to meet OEM specifications.
