Use a representative trial to convert a catalogue reference into a production result.
Published ranges identify a possible configuration; they do not show how a particular batch of powder will feed, settle or respond to hopper refill. The trial should reproduce the product condition, pack opening, fill height and operating method expected in production. Agree the target and acceptance rules before the first fill is made.
Hold the important conditions constant
Record the product batch and density method, the screw or weigh tooling, hopper level, agitation or feed settings, container or film, target dose, fill height and measurement instrument. If the machine is tested at more than one target, treat each target as a separate condition. Include a refill event where hopper level may affect feed pressure or product aeration.
Record every result in the agreed sequence
A useful report lists each measured fill and identifies start-up, adjustment, refill and rejected fills. Calculate the mean, minimum, maximum and standard deviation for the agreed production sequence, then compare those results with the stated target and individual tolerance. Weight data should be read alongside observations on dust, spillage, headspace, seal contamination, container stability and product damage.
| Acceptance area | Agree before the trial | Evidence to retain |
|---|---|---|
| Dose performance | Target average, individual limits, handling of start-up fills and the sequence to be measured. | Individual results, summary statistics, adjustments and rejected-fill reasons. |
| Output | Whether the measure is filler cycles, finished packs or sustained line output, and the exact product and pack condition. | Timed run, stoppage log, refill events and the slowest line stage. |
| Pack quality | Acceptable dust, spillage, headspace, closure or seal condition and finished-pack presentation. | Photographs or video, inspection record and any pack rejected for reasons other than weight. |
| Changeover | SKU change, cleaning boundary, parts to remove, settings to change and line-clearance requirement. | Observed sequence, tools used, inaccessible residue points and restart checks. |
