Working with packaging factories all over the world, I've seen too many unplanned production halts caused by poor spare parts management, even a small faulty part can shut down the whole cap production line, leading to unexpected delivery delays and profit losses, so proper spare parts handling is more important than most buyers realize.

From our years of after-sales experience, we suggest keeping core critical components in stock, customized molds, transmission belts, and photoelectric sensors. These parts wear out gradually or fail accidentally, and they directly affect line operation.
Store these spare parts in a clean, dry, dust-free space, humid or dirty environments will easily damage parts and shorten their service life. And we always recommend using manufacturer genuine parts, they have better compatibility with your aluminum threaded cap, anti-theft cap and metal box processing equipment, avoiding matching problems that cause more downtime.

It's also necessary to check your spare parts inventory every 1-2 months, mark the usage cycle of wearing parts, and replenish them in advance.
At Yantai Kunpeng, we provide a detailed, customized recommended spare parts list for every set of equipment we ship. The list clearly marks stock quantity and replacement cycle, helping you manage inventory easily and cut unnecessary downtime as much as possible.
