Extend Die Life for Aluminum Cap Production Lines

Many aluminum cap manufacturers face a common headache: stamping dies wear out too quickly. Frequent die changes not only raise your production cost but also cause frequent line downtime, directly affecting your output efficiency.

The main reasons usually come down to three points: insufficient lubrication during production, improper die material hardness, and excessive stamping pressure settings. Based on our years of experience in building aluminum cap production lines, we have summed up practical ways to help extend die service life.

First, we use carbide dies with titanium coating on the surface, which greatly improves wear resistance. Second, we suggest applying special lubricating grease every 8 hours to maintain stable lubrication. Third, we help customers optimize rolling and stamping parameters to avoid overloading the dies.

As a professional manufacturer from Yantai Kunpeng Packaging Equipment Co., Ltd., we provide complete aluminum cap production lines with matched high-performance dies. Under normal production conditions, our dies can reach approximately 8 million strokes, while the industry average is mostly around 5 million strokes.This difference can significantly reduce your die consumption cost and decrease the frequency of mold changes. For aluminum cap producers, longer die life means more stable production, fewer interruptions, and better control over overall manufacturing expenses.
