In automotive manufacturing, the quality of every stamped component directly affects vehicle safety, assembly precision, and long-term durability. Whether you are sourcing automotive stamping dies for a new vehicle program or looking for a reliable supplier of sheet metal parts, choosing the right manufacturing partner is one of the most critical decisions your procurement team will make. Dian Stamping, operating under LINHAI DIAN MOULD CO., LTD, has been delivering precision tooling and stamped components to global automotive OEMs since 2003.

A Factory with Proven Scale and Capability

Dian Stamping is not a trading company — it is a full-fledged manufacturing facility covering approximately 50,000 m² in Huangyan, Taizhou, Zhejiang Province. The company's die workshop alone spans 4,000 m², and its team of roughly 110 employees includes around 35 experienced die designers and technicians. With an annual capacity of approximately 2,000 sets of medium and small stamping dies and a reported annual die turnover of about RMB 50 million, Dian Stamping has the production muscle to support both prototype development and high-volume production runs.

A planned 35,000 m² facility expansion featuring new press and coating lines further underscores the company's commitment to long-term growth and technological advancement.

Comprehensive Product and Service Portfolio

Dian Stamping offers a full spectrum of manufacturing services under one roof, eliminating the need for multiple suppliers and reducing supply chain complexity.

Trusted by Global Automotive OEMs

Dian Stamping's customer roster includes major automotive brands such as KIA, BYD, Toyota, Honda, Suzuki, and Geely. The company exports its tooling and stamped components to more than 10 countries worldwide, serving both OEMs and Tier 1 suppliers. This track record demonstrates that Dian Stamping consistently meets the stringent quality, delivery, and cost requirements of global automotive manufacturers.

Quality Management and Certifications

Quality assurance is embedded in every stage of production at Dian Stamping. The company operates under an ISO 9001-certified quality management system and follows IATF 16949-oriented automotive manufacturing and quality practices. From raw material inspection to final die tryout, every step is documented and traceable. The company also offers free metal samples upon request (with freight paid by the customer), allowing potential partners to evaluate quality firsthand before committing to production.

Customization and Flexible Delivery

Dian Stamping accepts custom orders from 2D drawings, 3D data, or physical samples. Prototype services are available for new product development. Typical delivery lead times are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, subject to project complexity and requirements. This flexibility allows customers to bring new vehicle programs to market faster while maintaining cost control.

Beyond Stamping: A One-Stop Solution

What sets Dian Stamping apart is its ability to provide end-to-end solutions. In addition to stamping dies and sheet metal parts, the company manufactures checking fixtures and welding jigs — essential tools for quality assurance and production assembly. A checking fixture, for example, allows manufacturers to quickly verify whether a stamped part meets specified dimensions, eliminating the need for time-consuming manual measurements with calipers or micrometers. This integrated approach means customers can source dies, fixtures, and jigs from a single, accountable partner.

Why Factory-Direct Matters

Dian Stamping identifies itself as a factory, not a trading company. This distinction matters for buyers seeking competitive pricing, direct technical communication, and faster problem resolution. By working directly with the manufacturing team, customers gain access to factory pricing, real-time production updates, and collaborative engineering support throughout the project lifecycle.
