This image shows a progressive stamping die used for manufacturing automotive sheet metal components through continuous strip feeding. Progressive dies are widely used in automotive manufacturing because they allow multiple forming and cutting operations to be completed within a single die system, ensuring high efficiency and consistent production quality.

As the sheet metal strip advances through the progressive die, each station performs a specific operation such as piercing, trimming, bending, or forming. This step-by-step forming process enables complex automotive parts to be produced with high dimensional accuracy while maintaining stable high-volume production.

Dongguan Changdong Tool & Die Co., Ltd. specializes in the design and manufacturing of progressive stamping dies, transfer dies, and precision metal forming tooling. Founded in 2012, the company relocated in 2015 to a modern 4,000 square meter manufacturing facility equipped with advanced machining equipment and stamping presses.

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

Changdong’s tooling is widely used in industries such as automotive manufacturing, electronic equipment, home appliances, and industrial machinery, producing parts including automotive bumpers, A/B pillars, chassis components, seat structures, instrument panel brackets, and engine heat shields.
