A fill-by-weight auger filler uses weighing feedback to help control the final dose. This can be useful where product value, label weight or batch variation makes basic volumetric dosing less suitable.
Fill-by-weight auger filler advice for powder products where weight feedback, accuracy and controlled dosing are important.

Send product detailsThese checks help decide whether the right route is compact, semi-automatic, automatic, VFFS or a complete powder filling line.
Check target tolerance and weighing resolution.
Plan how tare weight changes will be handled.
Consider speed trade-offs when weighing every fill.
The machine uses weighing to control or verify the powder dose.
It can be, depending on the weighing method and tolerance.
When accuracy, giveaway reduction or compliance is more important than maximum speed.
Send your powder, pack and output target and we will help point you towards a suitable auger filling option.
| Method | Operation | Best evidence |
|---|---|---|
| Separate weighing device | The programmed auger dose is delivered, then the operator checks or refines the result on a separate platform. | LU-FM710 documented route, sampling frequency and correction method. |
| Live load-cell filling | The pack remains on a weighing platform while the auger changes from bulk to fine speed and stops near target. | LU-FM750F net-weight configuration, bag stability and cycle study. |
Powder feed, auger cut-off, vibration, draughts, pack support and settle time can affect the measured result. Define them on the trial and FAT guide.
For products better suited to direct vibratory or multihead weighing, use the auger versus weigh guide.
A net-weight auger filler enquiry usually means the buyer wants auger handling with weight-based evidence. The auger still controls the product feed, but the acceptance method may include weighing, checkweighing, reject handling or feedback to reduce avoidable overfill.
To make this route meaningful, Lancing needs the product sample, target weight, tolerance, pack tare variation, scale resolution and whether the weight is checked during filling, after filling or at the end of the line. Compare the route with the volumetric and gravimetric powder filling guide.
A fill-by-weight auger route may use weighing during the filling process, while a checkweigher verifies the finished pack after filling. A project can need one, both or neither, depending on the product, tolerance, output and quality procedure.
Fill-by-weight and checkweighing are not the same. Fill-by-weight uses weight as part of the filling method, while checkweighing verifies the pack after the fill has been made.
For powders with density changes, using both concepts may be useful: weight support can improve dosing control and post-fill checkweighing can provide accepted-pack evidence.
Plan post-fill checkweighing →For auger filling, the recipe setting is only useful when it is linked to a defined powder, tooling set, hopper state and weighing method. If the product settles, aerates or restarts differently after a stop, the finished-pack result may need an extra verification check.
Use the calibration and weight verification guide with checkweighing after auger filling when the project needs documented pack-weight evidence.
