This image shows the die assembly workshop at Dongguan Changdong Tool & Die Co., Ltd., where experienced technicians assemble and adjust multiple metal stamping dies before production. Each die set consists of numerous precision components including punches, die plates, guide pillars, inserts, and structural frames that must be carefully aligned to ensure stable stamping performance.

During the assembly process, technicians verify dimensional accuracy, component fit, and movement clearance to ensure that the stamping dies meet strict engineering requirements. Proper assembly is essential for achieving consistent stamping quality, longer tool life, and reliable high-volume production.

Founded in 2012, Changdong specializes in the design and manufacturing of precision metal stamping dies including progressive dies, transfer dies, and single-operation dies up to 4 meters in length. The factory covers approximately 4,000 square meters and operates under ISO9001 and IATF16949 quality management systems, supporting automotive and industrial stamping projects.
