This image shows the structural layout of a precision progressive stamping die manufactured by Dongguan Changdong Tool & Die Co., Ltd.. Progressive tooling structures are designed to support multiple stamping operations within a single die set, allowing sheet metal materials to move through several forming, cutting, and shaping stations during continuous stamping production.

The die structure integrates guide pillars, support plates, positioning blocks, and forming stations to ensure stable alignment and repeatable stamping accuracy. High precision machining and careful assembly are essential to guarantee smooth strip feeding, consistent forming quality, and long tooling service life.

Founded in 2012, Changdong specializes in the design and manufacturing of metal stamping dies including progressive dies, transfer dies, and single-operation tooling up to 4 meters in length. The factory occupies approximately 4,000 square meters and operates under ISO9001 and IATF16949 quality management systems, providing reliable tooling solutions for automotive and industrial sheet metal components.

With in-house engineering, machining, assembly, and stamping capabilities, Changdong offers a complete one-stop manufacturing service for high-precision stamping tooling projects.
