How to choose a weigh filler for your product and pack format.
A practical buyer guide for dry-product producers comparing weigh filling machines, weight fillers, auger fillers and integrated bagging lines.
Decision order
- Product behaviourFlow, dust, fragility, density and bridging risk.
- Target fill and toleranceMinimum, maximum, giveaway limits and accuracy expectation.
- Pack formatOpening size, pack stability, seal, closure and finished presentation.
- Output and labourPacks per minute, operator loading, shift pattern and future volumes.
Do not start with the model number.
The safest route is to decide whether the process needs vibration-fed weighing, combination weighing, screw dosing or an integrated bagging line. The machine model should follow that decision, not lead it.
Use the links below when you are ready to compare linear weigh fillers, multihead weighers, auger fillers and VFFS lines in more detail.

Use this table to decide which route is worth discussing for your product and pack.
| Need | First route to compare | Reason | Next page |
|---|---|---|---|
| Free-flowing seeds, beans, granules or small parts | Linear weigh filler | Simple weight-controlled dosing for many consistent products. | Linear route |
| Fast packing of irregular snacks or pet food | Multihead combination weigher | Combination weighing can improve speed and target-weight accuracy. | Multihead route |
| Fine powders, spices or dry blends | Auger filler | Screw dosing gives more controlled delivery for many powder behaviours. | Auger route |
| Bagging from roll film | VFFS weigh filling line | The line forms the bag, doses product and seals the pack in one process. | VFFS route |
Choosing a weigh filler.
Quick answers to common early-stage specification questions.
What information does a supplier need to recommend a weigh filler?
A useful enquiry includes product type, flow behaviour, target fill weight, tolerance, pack format, target output, available space and any downstream equipment.
Is a weigh filler the same as a volumetric filler?
No. A weigh filler controls the dose by weight, while volumetric filling controls the dose by volume. Product density variation can make this distinction important.
Can one weigh filler handle many products?
Often a machine can handle a range, but change parts, cleaning, feed behaviour, accuracy and speed expectations decide how practical that range is.
Send the product, target weight, pack format and output target.
That gives Lancing enough information to compare a linear weigher, multihead weigher, auger filler or integrated bagging line.
Build the shortlist from evidence, then compare models.
Use the same decision order for each supplier or machine so headline speed, head count and range are compared on a like-for-like basis.
| Decision | Evidence to supply | What it changes |
|---|---|---|
| 1. Product behaviour | Representative sample, bulk density, particle size, dust, static, fragility, moisture and bridging behaviour. | Feeder, hopper, contact path and whether linear, multihead or auger dosing is practical. |
| 2. Target-weight range | Smallest, normal and largest target, tolerance basis and declared quantity where applicable. | Weigh-hopper size, head utilisation, tooling, trim-feed control and relative accuracy expectation. |
| 3. Pack format | Actual pouch, bag, jar or tub dimensions, opening, film and seal/closure method. | Discharge chute, bag clamp, container support, former, sealing and product-drop path. |
| 4. Output point | Required accepted finished packs per minute and planned shifts. | Automation level, operator loading, product feed, number of heads and downstream bottlenecks. |
| 5. Quality evidence | Mean, standard deviation, min/max, under-target and reject rules, product-damage limit and seal acceptance. | Trial protocol, checkweigher requirement and contractual acceptance criteria. |
| 6. Cleaning and changeover | Allergen/cross-contamination standard, product sequence, cleaning method and changeover target. | Access, removable parts, tooling sets, recipes and maintenance plan. |
| 7. Line integration | Upstream feed, downstream machine, controls, utilities, layout and safety responsibilities. | Interface signals, buffers, conveyors, guarding and commissioning scope. |
Choose the owner of each specialist question.
Use this site for weight-based dosing, target-weight evidence and weighing-line integration. Use Combiweigh for broader linear and combination-weigher model coverage, Auger Fillers for powder screw-dosing detail, Form Fill & Seal for reel-fed baggers and Pouch Fillers for premade pouch machinery.
This avoids choosing a machine from a keyword or model name before the engineering route has been established.
Minimum evidence for a useful comparison.
- One written product and pack brief used for every option.
- Published figures accompanied by product, target and test conditions.
- A sample-trial plan with agreed statistics and acceptance rules.
- A line layout showing feed, filler, pack handling and inspection.
- Cleaning, utilities, operator and maintenance responsibilities.
- Clear exclusions and assumptions in the quotation.
