This image shows a progressive die mold set consisting of both the upper die and lower die sections used in precision sheet metal stamping. Progressive dies are built with multiple stations that allow different forming operations to be completed sequentially as the metal strip moves through the tooling.

The upper die typically contains components such as punches, punch holders, and guide systems, while the lower die includes die plates, inserts, and positioning components that support accurate forming and cutting operations. Together, the upper and lower die structure ensures stable stamping performance and consistent part quality during high-volume production.

At Dongguan Changdong Tool & Die Co., Ltd., progressive die sets are manufactured using advanced machining technologies and strict quality control processes. The company was established in 2012 and relocated to a 4,000 square meter manufacturing facility in 2015, allowing expanded production capacity and improved tooling capabilities.

Changdong is equipped with a wide range of precision equipment including CNC machining centers, milling machines, grinding machines, drilling machines, wire cutting systems, and welding equipment. The factory also operates stamping presses ranging from 45 tons to 800 tons, enabling the production of both large automotive components and small precision metal parts.

Changdong provides complete services from CAE simulation and mold design to tooling manufacturing and metal stamping production, supporting industries such as automotive manufacturing, electronic equipment, household appliances, and industrial machinery.
