In the fast-paced automotive industry, the quality of your tooling determines the quality of your production. Choosing the right partner for stamping dies, sheet metal parts, checking fixtures, and welding jigs is a strategic decision that impacts cost, lead time, and end-product performance.

LINHAI DIAN MOULD CO., LTD, operating as Dian Stamping Company, has been a dedicated manufacturer of stamping die solutions and automotive tooling since 2003. Headquartered in Huangyan, Taizhou, Zhejiang Province — one of China's most established manufacturing hubs — the company has grown from a specialized die workshop into a comprehensive one-stop manufacturing partner for global automotive OEMs and Tier 1 suppliers.

With over 20 years of industry experience, Dian Stamping has built a reputation for precision engineering, factory-direct pricing, and end-to-end service that spans the entire product lifecycle — from prototype development to mass production.

Dian Stamping offers four core product categories, each backed by deep engineering expertise and modern manufacturing capabilities:

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 skilled professionals, including approximately 35 die designers and technicians. With an annual capacity of about 2,000 sets of medium and small stamping dies and an annual die turnover of approximately RMB 50 million, Dian Stamping is well-equipped to handle both large-volume programs and custom-engineered projects.

The company is currently expanding with a new 35,000 m² facility featuring state-of-the-art press lines and coating systems, further strengthening its production capacity and quality control infrastructure.

Quality is embedded in every stage of Dian Stamping's manufacturing process. The company operates under an ISO 9001-certified quality management system and follows IATF 16949-oriented automotive manufacturing practices. Rigorous inspection protocols — including in-line checks, CMM (coordinate measuring machine) verification, and functional testing — ensure that every die, part, and fixture meets the highest standards of dimensional accuracy and durability.

Dian Stamping's commitment to quality and reliability has earned the trust of leading automotive brands worldwide. The company serves OEM customers including KIA, BYD, Toyota, Honda, Suzuki, and Geely, and exports to more than 10 countries across Asia, Europe, and the Americas. Application areas span body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems.

In a competitive global market, Dian Stamping differentiates itself through several key strengths:

• Factory-direct manufacturing — As a genuine factory (not a trading company), Dian Stamping offers competitive pricing with full control over quality and delivery.

• Customization flexibility — The company accepts custom orders based on 2D drawings, 3D data, or physical samples, with prototype services available for new product development.

• Material versatility — Capable of processing multiphase steel, advanced high-strength steel, aluminum alloys, stainless steel, and custom rolled and welded plate.

• Reliable lead times — Typical delivery is 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity.

• End-to-end solutions — From tool design and die manufacturing to stamping production, inspection fixturing, and welding assembly — all under one roof.
