Precision spool equal-height sleeves are essential machined components used in stamping dies to ensure accurate die alignment and consistent height control during stamping operations.

Dongguan Changdong Mold Co., Ltd. manufactures custom equal-height sleeves according to customer drawings and die requirements. These sleeves are produced through precision mechanical processing to achieve stable dimensions, smooth surface finish, and reliable performance in die assemblies.

With in-house machining capabilities including CNC machining, turning, milling, grinding, and drilling, Changdong is able to control dimensional accuracy and consistency for each sleeve. The sleeves are commonly used in progressive dies, transfer dies, and single-stage stamping dies to maintain die balance and reduce wear during long-term operation.

Founded in 2012, Changdong operates a 4,000-square-meter manufacturing facility and is certified to ISO9001 and IATF16949. By integrating die manufacturing experience with precision machining, Changdong provides practical and reliable mechanical components for stamping die applications.

These equal-height sleeves are suitable for automotive stamping dies, industrial tooling, and customized die structures where precise positioning and height control are required.
