Dian Stamping offers a complete range of tooling and manufacturing services under one roof, eliminating the need for multiple vendor coordination. The four core service categories cover the full spectrum of automotive metal forming needs:

Manufacturing Scale and Technical Capabilities

Dian Stamping\'s manufacturing infrastructure is built to handle demanding automotive programs. The company processes a wide range of materials including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel. Its die-making capabilities span progressive dies, transfer dies, and tandem/multi-station dies for large and medium-sized complex parts.

A planned 35,000 m虏 expansion featuring new press and coating lines will further increase production capacity and surface treatment capabilities, positioning Dian Stamping to meet growing demand from both existing and new customers.

Quality Assurance and Certifications

Quality is at the foundation of every project at Dian Stamping. The company operates under an ISO 9001 quality management system and follows IATF 16949-oriented automotive manufacturing practices. All tools and parts undergo rigorous inspection using advanced metrology equipment, including coordinate measuring machines (CMM) and in-line inspection processes.

For every project, the checking fixture is designed and manufactured alongside the stamping dies to ensure that dimensional verification is seamless and repeatable. This integrated approach 鈥?tooling and inspection fixture from a single source 鈥?eliminates the coordination gaps that often arise when dies and fixtures come from different suppliers.

Application Areas and Industry Experience

Dian Stamping\'s tooling and stamped parts are used across a wide range of automotive systems, including:
