Can line quality
Can seam quality for carbonated drinks.
For carbonated cans, filling and seaming must be treated as one linked quality step rather than two separate purchases.
Carbonated cans need controlled movement from filling to lid placement and seaming. The seamer must be matched to the can body, lid/end, change parts and target output. A project should define not only the filler but also how foam, headspace, lid application and seam quality will be checked.
| Can body and end | Send actual can bodies and ends for review rather than relying only on nominal volume. |
|---|---|
| Handoff time | Minimise unnecessary delay and unstable movement between filling and seaming. |
| Foam behaviour | Foam can affect lid application, seam cleanliness and filled appearance. |
| Seamer tooling | Tooling and change parts must match the can and end specification. |
| Quality checks | Visual seam checks and, where required, teardown or measurement routines should be site controlled. |
- Confirm 330 ml, 440 ml, 500 ml or alternative can formats.
- Provide end/lid details and supplier information where available.
- State whether the line needs one format or multiple changeovers.
- Discuss downstream rinse, dry, labelling, coding and pack-off needs.
Lancing can discuss machinery integration and handoff planning. Final seam acceptance should be controlled by the buyer’s quality procedure, competent personnel and can supplier requirements.
Buyer questions
Questions to resolve before specification.
Is the can seamer part of the filler?
It can be integrated in a line, but filling and seaming functions still need separate specification checks.
Can one seamer handle every can size?
Not without checking tooling, can body, end and change parts.
Why does foam matter before seaming?
Excess foam can affect lid placement, product loss, hygiene and consistency.
Should can samples be supplied?
Yes. The real can body and end are essential for a useful review.
