In the fast-paced world of automotive manufacturing, the quality of your tooling determines the quality of your vehicles. For over two decades, Dian Stamping has been the trusted partner behind some of the world's most recognized automotive brands, delivering precision-engineered automotive stamping dies that power production lines across the globe.

A Legacy Built on Precision and Trust

Established in 2003 in Huangyan, Taizhou, Zhejiang Province, LINHAI DIAN MOULD CO., LTD (Dian Stamping) has grown from a specialized tooling workshop into a comprehensive manufacturing partner spanning 50,000 square meters. With a dedicated die workshop of approximately 4,000 square meters and a team of 110 employees — including 35 highly skilled die designers and technicians — the company represents a formidable force in the progressive die stamping industry.

The company's annual capacity of approximately 2,000 sets of medium and small stamping dies, combined with a reported annual die turnover of around RMB 50 million, speaks to its operational scale and reliability. A newly planned 35,000-square-meter facility featuring advanced press and coating lines will further expand this capability, reinforcing Dian Stamping's commitment to continuous improvement.

Comprehensive Solutions Across the Automotive Supply Chain

What sets Dian Stamping apart from other stamping die manufacturers is its end-to-end service model. The company is not merely a tooling supplier — it is a one-stop manufacturing partner offering:

• Stamping Dies — Progressive, transfer, and tandem dies for large and medium-sized complex automotive parts, covering body-in-white, door systems, seating systems, instrument panels, and chassis components.
• Sheet Metal Parts — High-volume production of automotive and household-appliance stampings, custom metal parts, and welding assemblies with factory-direct pricing.
• Checking Fixtures — High-precision, GD&T-oriented inspection fixtures designed to eliminate measurement variability and ensure every part meets exact specifications.
• Welding Jigs — Custom fixtures for accurate, repeatable welding and assembly operations, supporting consistent quality across production runs.

Proven Quality That OEMs Trust

Dian Stamping's quality management system is built around ISO 9001 standards, with manufacturing practices aligned to IATF 16949 automotive requirements. This commitment to quality has earned the trust of global automotive leaders including KIA, BYD, Toyota, Honda, Suzuki, and Geely. The company exports to more than 10 countries, demonstrating its ability to meet international quality and delivery expectations.

The Factory Advantage: Direct Pricing, No Middlemen

As a factory rather than a trading company, Dian Stamping offers direct cost advantages that translate into competitive pricing for its customers. Customization is available from 2D drawings, 3D data, or physical samples, and prototype services are available to accelerate development cycles. Typical delivery is 30-40 days for steel stamping dies and approximately 70 days for casting stamping dies, subject to project scope.

The company's engineering team leverages advanced CAD/CAM software for die design and simulation, ensuring first-time-right tooling that minimizes costly trial-and-error during tryout. This approach reduces both time-to-production and overall project cost.

Beyond the Die: A True Manufacturing Partner

Dian Stamping's value proposition extends beyond tooling. The company's integrated services — from die design and fabrication to sheet metal stamping, welding, and assembly — mean customers can consolidate their supply chain, reduce logistics complexity, and maintain tighter quality control. For automotive OEMs and Tier-1 suppliers seeking a reliable, scalable, and cost-effective manufacturing partner in Asia, Dian Stamping represents a proven choice backed by two decades of continuous operation.
