In today's competitive automotive supply chain, OEMs and Tier 1 suppliers are no longer looking for just a die maker or a parts supplier. They need a manufacturing partner capable of managing the entire production lifecycle — from tool design and stamping to welding, finishing, and assembly. DIAN STAMPING (LINHAI DIAN MOULD CO., LTD) delivers exactly that: a vertically integrated, one-stop solution for metal stamping parts, tooling, and assembly services.
More Than a Parts Supplier: A Vertically Integrated Manufacturing Partner
Founded in 2003 and headquartered in Hongguang Industrial, Yanjiang, Linhai, Taizhou, Zhejiang Province, DIAN STAMPING has grown into a comprehensive manufacturing enterprise with approximately 50,000 square meters of production space. The company operates a dedicated die workshop of 4,000 m² and is backed by a planned 35,000 m² expansion that will add new press lines and automated coating facilities.
With around 110 employees — including 35 die designers and technicians — DIAN STAMPING produces approximately 2,000 sets of medium and small stamping dies annually, with a reported annual die turnover of around RMB 50 million. This scale and consistency have earned the trust of globally recognized automotive brands including KIA, BYD, Toyota, Honda, Suzuki, and Geely.
Full-Spectrum Tooling and Stamping Capabilities
DIAN STAMPING specializes in the design and manufacture of a wide range of automotive stamping dies, including progressive dies, transfer dies, and tandem dies. The company processes multiple material types — multiphase steel, aluminum, custom rolled steel, welded plate, and stainless steel — enabling engineers to choose the optimal material for each application without compromise.
What sets DIAN STAMPING apart is its complete vertical integration. The service chain covers every step from tool and die manufacturing to stamping production, welding, surface treatment (including electrophoresis and powder coating), and finished product assembly. This end-to-end approach eliminates the risks and delays associated with multi-vendor coordination, while ensuring consistent quality at every stage.
Precision Assembly and Quality Control Infrastructure
Beyond stamping, DIAN STAMPING provides comprehensive assembly support through its dedicated checking fixture and welding jig divisions. The company's checking fixtures are designed and manufactured to GD&T standards, ensuring every stamped component meets the tight tolerances demanded by modern automotive production. Welding jigs and fixtures are built for high-accuracy assembly, supporting both manual and robotic welding processes.
Each die undergoes rigorous tryout and validation before shipment, and the company's quality management system is certified to ISO 9001 and aligned with IATF 16949 standards. As a recognized National High-Tech Enterprise and Zhejiang Provincial Technology-based SME, DIAN STAMPING operates with a quality-first mindset backed by documented procedures and continuous improvement practices.
