Capping machine troubleshooting: common issues to check
Poor capping results are not always caused by the capping machine. The cap, bottle, product, feeding method and line handling can all affect the finished pack.

Lancing can help shortlist practical capping machinery after reviewing cap type, neck finish, bottle stability, output target, torque requirement and the way caps are presented to the machine.

Poor capping results are not always caused by the capping machine. The cap, bottle, product, feeding method and line handling can all affect the finished pack.
Ask about this application →Check cap torque, liner condition, neck finish, filling contamination around the neck, cap seating and whether the bottle is stable during tightening.
Look for bottle rotation, worn tooling, incorrect chuck fit, cap variation, unstable guides, operator placement differences and incorrect machine settings.
Jams and misfeeds often come from cap geometry, orientation, static, damaged caps, bowl settings, overfilling the feeder or trying to feed a closure that needs specialist handling.
Photos, dimensions and target output help identify the most likely capping route. Physical samples are normally the best way to confirm tooling, cap feeding and bottle support.
Cross-threading can be caused by poor cap presentation, bottle misalignment, thread variation, cap damage or the capper engaging before the cap is correctly seated.
Bottles can spin if side belts, clamps, nests or guides are not supporting the container well enough for the required torque.
Lancing can review samples, photos and line details to help identify whether the issue is machine setup, tooling, cap feed or packaging compatibility.
