Direct answer
T‑cork quality control should check the seated height, closure straightness, top condition, bottle-neck condition, retention or removal evidence, and whether rejected bottles are separated from good output. The checks should be measurable enough to use during trials, FAT and routine production.
Finished-bottle inspection checklist
| Check | What to define | Why it matters |
|---|---|---|
| Finished height | Measurement point, tolerance band and sample size. | Shows whether the closure has been inserted to the agreed visual and functional position. |
| Straightness | Maximum visible tilt or inspection method. | Detects off-centre insertion, poor support or guide problems. |
| Top condition | Allowed marking, scuffs, coating damage or logo misalignment. | Protects premium presentation and saleable pack appearance. |
| Neck condition | Cracks, chips, stress marks, residue and product contamination. | Identifies unsafe or unacceptable packs before downstream handling. |
| Retention evidence | How removal or retention is assessed and recorded. | Separates machine seating from the closure/bottle fit decision. |
| Reject control | What happens to bottles that fail a check. | Prevents mixed good and suspect product during production. |
Questions buyers ask
Should T‑cork inspection be manual or automatic?
Manual inspection can be suitable for small runs and subjective cosmetic checks. Automatic or assisted inspection becomes more relevant where output is higher, the reject decision must be consistent, or downstream equipment cannot tolerate tilted or high closures.
Can the corking machine guarantee removal force?
The machine can control seating conditions, but removal force depends on the bottle and closure fit, shank material, storage state and test method. Retention acceptance should therefore be defined with a repeatable test rather than assumed from machine stroke alone.
What should be recorded during a T‑cork trial?
Record the bottle batch, closure batch, machine setting, support tooling, sample count, finished-height results, cosmetic observations, rejects, restarts and any changes made during the test.
