If you're running a metal cap or metal box production line, you've almost certainly dealt with frustrating jamming issues on stamping and drawing equipment. Frequent stops and wasted material cut into your efficiency and raise production costs, which is why we at Yantai Kunpeng Packaging Equipment design our lines to directly solve these pain points.
Jamming usually comes from a few common issues: sharp burrs on raw material sheets, uneven or insufficient lubrication, poorly chamfered molds, feeding speed that's too high, or slightly misaligned positioning pins.
From our on-site experience, we've put together a simple 5-step method to get your line running smoothly again:
1. Stop and cut power, then safely clear jammed scrap.
2. Smooth sheet edges to remove burrs that catch during forming.
3. Check your lubrication system to ensure drawing oil sprays evenly.
4. Lower feeding speed by 10%–15% for more stable feeding.
5. Calibrate positioning pins to keep deviation within 0.05mm.
Our tamper-evident cap and metal box production lines include built-in automatic lubrication and early jamming detection. Many of our customers have seen unplanned downtime reduced by roughly 80% in daily production. We focus on real, field-tested improvements rather than overstated claims, helping metal packaging producers run more stable, consistent operations with less interruption.
