In the competitive world of automotive manufacturing, the quality of your tooling directly determines the quality of your production. For over two decades, Dian Stamping (LINHAI DIAN MOULD CO., LTD) has established itself as a trusted partner for global automotive OEMs seeking reliable, precision-engineered stamping solutions. From body-in-white components to complex chassis parts, Dian Stamping delivers end-to-end manufacturing capabilities that reduce supply chain complexity and lower total cost of ownership.

At the heart of Dian Stamping's offering lies its expertise in automotive stamping dies. The company specializes in progressive, transfer, and tandem dies designed for large and medium-sized complex parts. With an annual capacity of approximately 2,000 sets of medium and small stamping dies, the facility is equipped to handle both prototyping and high-volume production runs.

The modern 50,000 m² manufacturing facility in Huangyan, Taizhou, Zhejiang Province houses a dedicated 4,000 m² die workshop staffed by approximately 35 die designers and technicians. This in-house design capability ensures that every die is optimized for manufacturability, durability, and cost-efficiency from the very first drawing.

For automotive OEMs requiring high-volume production with consistent quality, progressive die stamping is the technology of choice. Dian Stamping's progressive die solutions enable multiple operations — including blanking, forming, coining, and piercing — to be performed in a single press stroke. This eliminates intermediate handling, reduces cycle times, and ensures part-to-part repeatability across millions of cycles.

The company processes a wide range of materials including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel, giving OEMs the flexibility to meet evolving lightweighting and performance requirements.

What sets Dian Stamping apart from other stamping die manufacturers is its vertically integrated service model. Beyond tooling, the company offers:

This one-stop approach means OEMs can source their tooling, production parts, inspection fixtures, and assembly tooling from a single qualified supplier — eliminating coordination overhead and ensuring consistent quality throughout the supply chain.

Dian Stamping's customer roster includes major automotive brands such as KIA, BYD, Toyota, Honda, Suzuki, and Geely, with exports to more than 10 countries. The company's quality management system is ISO 9001 certified, and its manufacturing practices align with IATF 16949 standards for automotive production.

Typical applications include:

As a factory rather than a trading company, Dian Stamping offers direct pricing without intermediary markups. Typical lead times are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity. The company also offers prototype services and free metal samples (with freight paid by the customer) to validate designs before full-scale production.

For automotive OEMs and Tier suppliers seeking a reliable, cost-competitive partner for stamping dies and production parts, Dian Stamping combines more than 20 years of experience, a 50,000 m² facility, in-house engineering, and a comprehensive service portfolio under one roof. Whether you need progressive dies for high-volume production or custom checking fixtures for quality assurance, Dian Stamping delivers the precision, quality, and value that today's automotive industry demands.
