Precision Metal Stamping for the Automotive Industry

The automotive industry demands precision, consistency, and cost-efficiency at every stage of vehicle manufacturing. When it comes to metal forming and tooling, selecting the right stamping partner directly impacts production quality, lead times, and overall supply chain performance. As experienced stamping die manufacturers, LINHAI DIAN MOULD CO., LTD (Dian Stamping) has earned its reputation as a trusted partner for automotive OEMs worldwide.

Since 2003, Dian Stamping has operated from a 50,000 m² state-of-the-art facility in Huangyan, Taizhou, Zhejiang Province — one of China's most established manufacturing hubs. With a dedicated die workshop spanning 4,000 m², a skilled team of approximately 110 employees including 35 die designers and technicians, and an annual capacity of roughly 2,000 sets of medium and small stamping dies, the company delivers both scale and precision. The reported annual die turnover of approximately RMB 50 million reflects the trust placed in Dian Stamping by major automotive brands.

Comprehensive Stamping Solutions Under One Roof

Dian Stamping specializes in a full spectrum of metal forming services. The company's core expertise lies in precision automotive stamping dies, covering progressive, transfer, and tandem die technologies for large and medium-sized complex parts. Whether you need progressive die stamping for high-volume production runs or transfer dies for intricate multi-step forming, Dian Stamping's engineering team designs and builds tooling that meets the tightest tolerances.

Beyond tooling, Dian Stamping offers end-to-end manufacturing capabilities. The company produces stamped sheet metal parts, checking fixtures, welding jigs, welding parts, and assembly components — making it a true one-stop partner for automotive OEMs and Tier suppliers. Application areas span body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems.

Dian Stamping processes a wide range of materials including multiphase steel, aluminum, custom rolled and welded plate, and stainless steel, giving customers flexibility across different vehicle platforms and component requirements.

Quality Systems and Automotive-Grade Standards

Quality assurance is embedded in every stage of Dian Stamping's manufacturing process. The company operates under an ISO 9001 quality management system and follows IATF 16949-oriented automotive manufacturing practices. This commitment to quality is reinforced by the company's precision checking fixtures — purpose-built inspection tools that verify dimensional accuracy for stamped components and welded assemblies, eliminating individual measurement variations and ensuring every part meets OEM specifications.

For customers requiring prototype validation, Dian Stamping offers prototype services that allow design verification before mass production. Whether you provide 2D drawings, 3D CAD data, or physical samples, the engineering team can develop custom dies and stamped parts tailored to your exact specifications.

Factory-Direct Pricing and Global Delivery

As a factory rather than a trading company, Dian Stamping offers competitive pricing without compromising quality. Typical delivery times are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity. The company serves customers in more than 10 countries and has built long-term relationships with global automotive brands including KIA, BYD, Toyota, Honda, Suzuki, and Geely.

A planned 35,000 m² new facility featuring additional press and coating lines will further expand Dian Stamping's capacity, allowing the company to serve a growing global customer base with even faster turnaround times.
