Real customer question
Our bottle mouths need foil sealing before the outer cap is applied. We want to know if a benchtop machine can do it first, and also evaluate future expansion to a six-head line, and hope to screen for defects like missing foil, low heat, or wrinkles after sealing. How should we select equipment in stages?
First determine the packaging route
For cap-less bottle mouth projects, first confirm the induction sealing window with containers and foil assemblies, then choose the IF110 benchtop horizontal-shift machine or the IF610 six-head linear line based on loading/unloading method. If online screening is needed, evaluate the FI310 thermal imaging solution downstream.
Manual loading/unloading and benchtop shifting
Suitable for: projects that need to establish a process window with real bottle samples and mainly use manual bottle placement and removal on site. Advantages: IF110's benchtop horizontal-shift structure makes it easy to confirm positioning, shifting, and induction sealing in one independent station. Limitations: IF110 is configured as an independent benchtop station; automatic loading/unloading, inspection, and line integration need separate confirmation. Not recommended: when the project clearly requires continuous conveying, multi-position synchronization, and complete upstream/downstream interlocks, the entire line should not be estimated based only on a benchtop station. Equipment direction: focus on evaluating YJ-IF110 and conduct trial runs with actual containers, foil, and fixtures.
Continuous conveying and six-head parallel sealing
Suitable for: projects with stable bottle shapes, wanting linear conveying and multi-position locating carriers, and ready to define full line cycle time. Advantages: IF610's six parallel sealing heads and linear carrier structure are suitable for further discussion of multi-position sealing and upstream/downstream integration. Limitations: single-cycle meaning, actual capacity, loading release logic, interlocks, and conveying interfaces have no universal fixed values. Not recommended: when bottle shape is not finalized, foil assembly is still changing frequently, or only small trial production is needed on site, it is not advisable to freeze the six-head configuration. Equipment direction: focus on evaluating YJ-IF610 and conduct cycle acceptance with a complete line and representative samples.
Add thermal imaging screening after sealing
Suitable for: projects that want to establish online screening for defects such as missing foil, reversed foil, missing edge, damage, wrinkles, overheating, low heat, tilted caps, loose caps, or false seals. Advantages: FI310 can complete thermal image acquisition, feature analysis, result recording, and alarm or rejection signal linkage according to the project. Limitations: thermal images are process and defect screening evidence and cannot directly replace leak, peel, or seal strength tests. Not recommended: when there are no representative good and defective samples and no actual line speed and thermal environment data, inspection speed and accuracy should be determined after on-site blind testing. Equipment direction: evaluate YJ-FI310 downstream of the induction sealing equipment and determine acceptance boundaries based on blind test results.
Recommended equipment route: Step 1: Confirm the container and aluminum foil assembly
First use actual samples to confirm whether the bottle mouth and aluminum foil assembly provide a repeatable test basis.
Recommended equipment route: Step 2: First rule out the conventional inline route with caps
If the container can provide pressing conditions by screwing on an outer cap, first compare conventional inline solutions. Projects without an outer cap then proceed to IF110 or IF610.
Recommended equipment route: Step 3A: Benchtop station trial production
Manual loading/unloading projects can first confirm fixture positioning and the induction sealing window at a standalone station.
Recommended equipment route: Step 3B: Six-head line evaluation
Continuous production projects need to confirm multi-station carriers, conveying cycle time, and front/rear interlocking as a complete line.
Recommended equipment route: Step 4: Post-stage anomaly screening
After the sealing process is stable, use representative defect samples to establish thermal imaging screening and alarm or rejection boundaries.

Sample details
Actual container with close-up photos of the mouth and complete dimensions can first verify locating method, fixture boundaries, and subsequent sample needs.
Provide actual container, bottle mouth photos, mouth diameter, outer profile, and height.Confirm that the bottle mouth has no outer cap during sealing, so that equipment boundaries can be defined based on independent foil placement, bottle positioning, and induction station.
Indicate whether the sealing is confirmed to be without an outer cap.The composite structure and supply state of the foil assembly need to be checked together with the bottle material to arrange sealing trials rather than selecting a machine only by mouth diameter.
Provide foil assembly material, thickness, composite structure, and supply method.Hourly capacity, number of operators, and conveying method together determine whether to use a benchtop shift station or evaluate a continuous multi-head line.
Indicate target hourly capacity, number of operators, and whether continuous conveying is required.Upstream/downstream interfaces, conveying reference, and available space are used to verify line integration, operation and maintenance positions, and necessary safety protection.
Provide upstream/downstream equipment, conveying height, site layout, and safety requirements.First agree on how the seal itself will be accepted, then separately define thermal imaging screening targets to avoid equating temperature anomalies with leakage or strength conclusions.
Agree on acceptance methods for seal appearance, peel, leakage, and thermal imaging screening.Common selection mistakes
Common questions
The IF110 or IF610 can be evaluated, but actual samples of the container, bottle mouth, and foil assembly must be provided for confirmation.
For small-batch projects mainly using manual loading and unloading, the IF110 independent benchtop station can be prioritized for evaluation.
Judgment cannot be based only on the number of sealing heads; actual cycle time depends on carriers, conveying, release logic, and full-cycle testing.
FI310 can be used to screen for defects such as missing foil, reversed foil, missing edge, damage, wrinkles, overheating, low heat, tilted caps, loose caps, and false seals.
No, thermal images are process screening evidence; leakage conclusions still require corresponding verification methods.
They can be sold separately; whether to combine and the interface scope should be confirmed based on project goals and acceptance requirements.
