Finding a reliable stamping die manufacturers with decades of hands-on experience, proven quality systems, and genuinely competitive pricing is one of the toughest decisions in the global automotive supply chain. Whether you need progressive dies for high-volume production runs, transfer dies for complex geometries, or precision checking fixtures for quality assurance, the manufacturing partner you choose directly impacts your lead times, part quality, and bottom line.

With more than 20 years of industry expertise, LINHAI DIAN MOULD CO., LTD (Dian Stamping) has built a strong reputation as a reliable manufacturer of automotive stamping dies, sheet metal parts, checking fixtures, and welding jigs. Based in Huangyan, Taizhou, Zhejiang Province, the company serves a distinguished roster of global OEMs including KIA, BYD, Toyota, Honda, Suzuki, and Geely, with exports reaching more than 10 countries worldwide.

Comprehensive Manufacturing Capabilities Under One Roof

Dian Stamping operates a modern facility covering approximately 50,000 m², with a dedicated die workshop of 4,000 m². The company employs around 110 people, including roughly 35 highly skilled die designers and technicians. This team structure supports an annual production capacity of approximately 2,000 sets of medium and small stamping dies, with an annual die turnover of around RMB 50 million.

The company's four core product lines cover the full spectrum of automotive metal forming needs:

Quality Systems That Automotive OEMs Trust

Dian Stamping operates under an ISO 9001 quality management system and follows IATF 16949-oriented manufacturing practices. Every production stage, from material selection to tryout and final inspection, is subject to structured quality controls. The company can process a wide range of materials including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel, ensuring each component meets the required mechanical properties and dimensional tolerances.

For customers who need to validate part geometry, Dian Stamping's checking fixture solutions enable fast, reliable inspection of complex stamped parts. Press dies and checking fixtures go hand in hand — having both from the same supplier streamlines communication, reduces lead times, and ensures dimensional alignment between tooling and inspection equipment.

Factory-Direct Pricing With No Middleman Markup

Dian Stamping is a factory, not a trading company. This means customers get direct access to the manufacturing floor, shorter communication chains, and greater control over production schedules. The company's typical delivery time is 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity and current capacity.

The combination of factory pricing, consistent quality, and on-time delivery has made Dian Stamping a preferred sheet metal parts supplier for automotive Tier-1 suppliers and OEMs alike.

Flexible Customization and Prototyping Services

Dian Stamping accepts custom orders based on 2D drawings, 3D CAD data, or physical samples. Prototype services are available for new product development programs, and free metal samples can be provided upon request (with freight paid by the customer). This flexibility makes the company an ideal partner for both established OEMs launching new vehicle platforms and emerging automotive startups requiring agile tooling development.

Global Experience With Local Manufacturing Advantages

With exports to over 10 countries and a client list that includes some of the world's largest automotive manufacturers, Dian Stamping combines the cost advantages of a China-based factory with the quality standards expected by international OEMs. The company's planned expansion includes a new 35,000 m² facility featuring additional press and coating lines, further strengthening its capacity to serve growing global demand.

Long-term supply relationships are built on precision engineering, consistent delivery, and responsive customer service — values that have guided Dian Stamping since its founding in 2003.
