Filling machine sample trials that answer real buying questions
A useful trial reproduces the difficult product and pack conditions, records the setup and measures the result against an agreed decision — rather than producing a few attractive samples.
- Representative samples
- Defined test sequence
- Recorded evidence
Write the question the trial must answer
“See whether it fills” is too vague. The trial should close a named risk such as foam, stringing, particle passage, minimum dose, channel balance, bottle stability, closure-zone cleanliness or cleaning recovery.
Example decision statement
Confirm whether the proposed product path and nozzle method can fill the minimum and maximum production doses into the smallest bottle opening without unacceptable foam or external contamination, under cold-start, steady-run and pause/restart conditions.
Once the decision is written, the project team can choose the right samples, measurements and duration. A trial may show that the original method is suitable, that a setting or component should change, or that another filling principle is more robust.
Trial sample and evidence matrix
Label everything clearly and include only production-representative materials. Unidentified samples create uncertainty that cannot be closed later.
| Item | Minimum information to supply | What the trial can assess |
|---|---|---|
| Product | Name/code, batch, condition, temperature, viscosity behaviour, particles, foam, hazards and storage/handling notes. | Pump/path suitability, priming, fill profile, cut-off, cleaning and product-feed effects. |
| Containers | All sizes/shapes, production supplier/cavity where relevant, dimensions or drawings, expected variation and quantity. | Infeed, sensing, indexing, stabilisation, opening clearance, fill presentation and transfer. |
| Closures/components | Caps, plugs, pumps, liners or seals plus application requirement. | Wet-neck risk, handover time, capping/sealing compatibility and finished-pack checks. |
| Dose requirement | Minimum/normal/maximum dose, measurement basis, tolerance and sample rule. | Metering window, settings, repeatability and head-to-head comparison. |
| Production requirement | Sustainable output, batch duration, pauses, refill events and changeovers. | Cycle constraint, product supply, line interaction and restart behaviour. |
| Cleaning/changeover | Required method, segregation, recovery, waste and verification responsibility. | Access, retained product, strip-down, reassembly and first-off release. |
A representative filling trial sequence
The exact protocol should be agreed for the application, but the sequence below prevents a steady-state result from hiding start-up or recovery problems.
| Phase | Action | Record |
|---|---|---|
| 1. Identification | Verify product, packs, tooling, product path and measuring equipment. | Batch/sample references, configuration photographs and instrument status. |
| 2. Prime and first-off | Prime using the intended method and produce initial fills. | Prime quantity, air removal, first-off measurements and adjustments. |
| 3. Stable run | Operate long enough to reach representative product/path conditions. | Individual fills, channel identity, cycle observations, foam/drips and container handling. |
| 4. Disturbance | Introduce a planned pause, product-feed refill or agreed line interruption. | Response, container state, dose after restart and any operator intervention. |
| 5. Extremes | Run the most difficult product/dose/pack combinations. | Settings, results, limitations and whether a separate configuration is needed. |
| 6. Cleaning/change | Follow the intended clean or format-change method. | Time sequence, retained product, parts removed, errors and first-off result after reassembly. |
| 7. Review | Compare evidence with the decision statement. | Pass, conditional pass, further test or alternative method, with named assumptions. |
Arrange a representative product and pack review
Send the trial question with labelled product, containers, closures, target dose and acceptance method. Lancing can confirm the sample quantity and test sequence before materials are dispatched.
Filling machine sample-trial FAQs
How much product should be supplied for a filling-machine trial?
Enough to prime the complete product path, establish stable conditions, run repeated samples, include pauses and restarts, and leave a sensible margin. The exact quantity depends on product-path volume, dose and planned test sequence.
Should every product and pack be tested?
Prioritise combinations that create different engineering risks: minimum and maximum dose, thinnest and most viscous product, particles, foaming, least stable pack, smallest opening and any format with unique cleaning or closure requirements.
What makes a trial result repeatable?
Record the product batch and condition, equipment configuration, tooling, settings, reference instrument, sample method, environmental or temperature factors, start state and sequence of events.
Can water be used instead of the production liquid?
Water can demonstrate basic movement and controls, but it cannot prove performance for a product with different viscosity, foam, stringing, particles, compatibility or cleaning behaviour.
What should happen when a trial cannot confirm a requirement?
Record the unresolved point, why the evidence was insufficient, what further sample or equipment change is needed and whether the quotation remains conditional.
