When sourcing automotive stamping dies, global OEMs and Tier-1 suppliers look for more than just competitive pricing. They need a partner who can deliver precision tooling, consistent quality, reliable lead times, and the ability to scale from prototype to high-volume production. Linhai Dian Mould Co., Ltd. (Dian Stamping) 鈥?a National High-Tech Enterprise based in Taizhou, Zhejiang Province, China 鈥?has built its reputation on exactly these capabilities since its founding in 2003.

With a production facility covering approximately 50,000 m虏, a dedicated die workshop of 4,000 m虏, and a planned new 35,000 m虏 facility featuring advanced press and coating lines, Dian Stamping is equipped to handle complex projects across the entire automotive manufacturing spectrum. The company serves well-known OEMs including KIA, BYD, Toyota, Honda, Suzuki, and Geely, and exports to more than 10 countries worldwide.

A One-Stop Manufacturing Partner

Unlike many tooling suppliers that focus on a single process, Dian Stamping offers a truly integrated service chain. The company handles everything from die design and development to sheet metal stamping, welding processing, powder coating, and finished product assembly 鈥?all under one roof with zero outsourcing. This end-to-end approach eliminates coordination headaches, reduces lead times, and ensures consistent quality control throughout the production lifecycle.

As experienced stamping die manufacturers, Dian Stamping specializes in progressive dies, transfer dies, and tandem/multi-station dies for large and medium-sized complex parts. Their in-house design team of approximately 35 die designers and technicians uses advanced CAD/CAM software to engineer tooling that meets exacting customer specifications.
