The image shows a stamping die during the tryout and sample verification stage. Die tryout is a crucial step in the tooling manufacturing process, where the stamping die is tested to ensure it can produce parts that meet design specifications.

During the tryout process, the stamping die is installed on a press machine and test runs are performed using the actual production material. The stamped metal strip shown in the image contains multiple finished parts produced during the testing stage.

These sample parts allow engineers to carefully inspect several critical factors, including dimensional accuracy, hole positioning, edge quality, and forming consistency. If necessary, adjustments can be made to punches, inserts, or forming sections to achieve optimal results.

The tryout stage also helps verify the functionality of each stamping station within the die. In multi-station tooling systems, each station performs a specific operation such as piercing, cutting, forming, or bending. Testing ensures that all operations work together smoothly within the progressive stamping sequence.

At Dongguan Changdong Tool & Die Co., Ltd., every stamping die undergoes a thorough tryout and inspection process before shipment. Sample parts are produced and inspected to confirm that the die meets engineering requirements and production standards.

This strict quality control process ensures that customers receive reliable stamping tooling capable of stable, high-volume manufacturing.
