Material And Process Optimization Improves Die Durability For Aluminum Cap ManufacturinG

In daily aluminum cap manufacturing, most factory operators encounter a common tricky issue: frequent die wear shortens production cycles and raises ongoing spare-part costs. After long-term cooperation and data accumulation with overseas packaging factories, Yantai Kunpeng has targeted this pain point by upgrading core die materials and surface processing techniques.

For all aluminum cap production molds, we consistently use Cr12MoV tool steel paired with TiN coating. This combination is not over-marketed fancy configuration, but a practical solution verified in high-frequency stamping scenarios, It delivers balanced hardness and wear resistance, adapting well to continuous repetitive punching work in mass cap production.

From our real field production statistics, the dies will generate minor conventional wear after approximately 3 million punching strokes, Instead of requiring full replacement at this stage, the molds can be restored through precise regrinding.

With scientific daily maintenance and multiple reasonable regrinding treatments, the comprehensive service life of our dies can reach around 30 million strokes in total. Compared with ordinary market molds, this optimization greatly cuts down clients' frequent die replacement work, reduces unexpected production downtime, and effectively controls the long-term operating cost of aluminum cap production lines.
