Trial and FAT guide
Powder sample trials and factory acceptance testing.
Define the evidence needed to qualify auger tooling, powder feed, pack presentation, fill repeatability, changeover and line recovery before delivery.

Purpose
A sample trial selects the configuration; FAT proves the agreed scope.
An early trial explores product behaviour, tooling and pack presentation. A factory acceptance test uses the agreed machine, production samples and acceptance plan to demonstrate the contracted functions before dispatch. Do not treat a short video or a few favourable fills as a complete FAT.
- Agree what is being selected and what is being accepted
- Use representative product batches and production packs
- Record conditions, settings and results in sequence
- Include start-up, stable running, refill, stop and restart
- Identify open actions and final site-dependent checks
Quantity planning
Lancing should confirm the product and pack quantity from fill weight, tooling trials, run length, changeover checks and downstream tests. Too little sample can prevent stable feeding or meaningful repeatability evidence.
Before samples are sent
Build a complete sample pack.
| Input | What to supply | Why it matters |
|---|---|---|
| Powder | Representative production batch, product description, safety information, storage condition and known flow issues. | Flow, dust, density and bridging determine hopper, agitation, screw and outlet choices. |
| Target fills | Minimum, normal and maximum weights with tolerances and how they are defined. | One tooling set may not cover every target efficiently. |
| Packs | Production jars, bottles, tubs, pouches or bags at dimensional limits, plus closures or film where relevant. | Opening, rigidity, headspace, static and closure route affect practical filling. |
| Measurement | Scale capacity, resolution, calibration status, tare method and sampling plan. | An accuracy result is only meaningful when the measurement system is stated. |
| Output | Packs per minute, hour or shift, operator tasks and downstream sequence. | The fill head cannot be assessed separately from presentation, weighing, settling and closing. |
| Cleaning | Required clean method, allergen or contamination matrix and change frequency. | Access and change-parts may determine the preferred machine route. |
FAT sequence
Test the conditions that expose instability.
Set the product
Record batch, density observations, hopper level, auger set and recipe.
Start-up study
Retain first fills and adjustments rather than discarding them from the evidence.
Stable run
Record consecutive weights, output condition, rejects and operator interventions.
Refill and restart
Challenge hopper replenishment and planned stops to expose drift or flooding.
Pack and line checks
Check rim or seal cleanliness, container stability, transfer, closing and interlocks.
Close actions
Record pass/fail, settings, deviations, open actions and site-dependent completion items.
Accuracy evidence must state the denominator.
Record whether the tolerance is expressed as grams, percentage of target, standard deviation, maximum error or another agreed measure. Include every result used in the conclusion and the scale resolution. Averages alone can hide individual out-of-limit packs.
Continue to the powder filling accuracy guide.
FAT does not replace site acceptance.
Final installation can introduce different utilities, extraction, floor conditions, product storage, operators and downstream equipment. Define which checks are repeated at site and how recipes, training and handover records are controlled.
Use the site-preparation guide.
Trial planning
Plan a powder trialAgree the evidence before shipping samples.
Send target weights, tolerance method, pack formats and required line functions so Lancing can state the sample quantity and test plan.
