This product shows the finished assembly stage of an automotive prototype stamping die, which is developed for soft tooling trial and early-stage vehicle development projects.

Prototype stamping dies are mainly used during the vehicle R&D phase to support trial stamping, part validation, and forming feasibility verification before mass production tooling is finalized. At the finished assembly stage, the die structure, guiding system, forming inserts, and functional components are fully assembled and prepared for tryout and adjustment.

Dongguan Changdong Mold Co., Ltd. specializes in the design and manufacturing of metal stamping dies and prototype tooling. Founded in 2012, the company operates a 4,000-square-meter manufacturing facility and is certified with ISO9001 and IATF16949 quality management systems.

Changdong is capable of producing prototype dies, single-stage dies, progressive dies, and transfer dies up to 4 meters in length, using both cast iron and steel plate structures. With stamping presses ranging from 45 tons to 800 tons, as well as complete in-house machining equipment including CNC, wire cutting, milling, grinding, drilling, and welding, Changdong provides one-stop solutions from CAE analysis and die assembly to tryout and prototype stamping.

Finished prototype stamping die assemblies are widely used for soft tooling trials, process optimization, and engineering validation, ensuring a smooth transition from prototype development to mass production.
