Cap feeding problems often start before the final jam becomes visible. Learn how to diagnose sorting, transfer, chute, spacing, and placement issues step by step.

Loose, crooked and overtightened caps do not always point to the same torque problem. This guide explains how to trace defects through cap placement, thread engagement, bottle holding, capping-head condition and package variation before making adjustments.

A practical bottle and cap changeover checklist covering bottle handling, cap feeding, capping tooling, height, timing, trial runs, change parts, and sign-off.

Stable capping depends on bottle control, cap placement, thread engagement, and tightening working together. This guide explains a practical setup sequence and sample-testing method before production starts.

Different closure types change more than the capping head. Compare feeding, guides, bottle holding, change parts, settings, and sample tests for screw, press, pump, and trigger closures.
