Compare the main automatic, compact and semi-automatic capping routes.
Supplier change
Treat a closure supplier change as a packaging qualification event.
Direct answer
After changing cap supplier, check the cap thread, liner or seal surface, grip area, material behaviour, feed orientation, cap height and removal-torque evidence against the approved pack. A cap that looks similar may still behave differently in the chute, on the thread or after storage.
| Check | Why it matters | Record |
|---|---|---|
| Thread fit | Controls how the cap starts and reaches final height. | Approved sample comparison and fault photographs. |
| Liner or seal surface | Can affect compression, leakage and later relaxation. | Integrity test method and timing. |
| Cap surface | Affects spindle-wheel grip and visible marking. | Cap material, ribbing and damage check. |
| Feed behaviour | Different moulding or weight can alter bowl, chute or elevator behaviour. | Feed recovery and double-feed observations. |
