Machine range
Choose from the four main weigh filling routes.
Start with your product behaviour, target weight, pack style and output target. The routes below help you compare the most likely machine types before you ask for advice.
Machine route
Multihead combination weighers
For higher-throughput portioning where speed, accuracy and pack presentation matter.
View route →
Machine route
Auger fillers
For powders, dry blends and products that need controlled screw dosing.
View route →
Machine route
VFFS weigh filling lines
For roll-film bagging lines that form, fill and seal in one connected process.
View route →Selection logic
Product behaviour decides the filling principle.
A free-flowing seed, an irregular snack, a dusty powder and a formed pouch line should not be treated as the same filling problem. Use the routes below to decide whether you need vibration-fed weighing, combination weighing, screw dosing or a complete form-fill-seal line.
Simple, accurate dosing
Good for many seeds, beans, granules and small components where a compact weigh filling machine is needed.
Speed and combination accuracy
Best where several weigh heads combine to hit a target weight quickly and consistently.
Controlled powder dosing
Useful for fine powders and dry blends where screw feeding gives better control than open vibration.
Form, fill and seal
Relevant when the machine needs to make a bag from roll film, dose product and seal the pack.
Applications

What makes a stronger weigh filler enquiry?
Send these details so the machine shortlist can be checked properly.
- Product name, flowability, dust level and particle size.
- Target fill weight, tolerance and pack size range.
- Pack format: pouch, bag, jar, tub, bottle, box or downstream connection.
- Target packs per minute, operator loading method and site footprint.
- Whether the line also needs conveying, sealing, capping, coding, checkweighing or labelling.
Weigh filler advice for dry-product packaging
Weigh Fillers UK helps manufacturers and contract packers compare weigh filling machines for dry products, powders, granules, coffee, tea, snacks, pet food, chemicals and hardware. Our advice is structured around real machine selection: linear weigh fillers, multihead combination weighers, auger fillers and VFFS weigh filling lines.
A useful recommendation starts with the questions that matter: what is the product, what is the target weight, how accurate does the fill need to be, what pack is being filled and what output is required? With those details, Lancing can compare the right weigh filler, powder filler or automated bagging line for your process.
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.
Verified reference data
Reference configurations with the conditions behind every figure.
Machine performance is only meaningful when the product, target weight, pack and test method are stated. These Lancing reference configurations are included to show the level of evidence used when a weigh filling route is shortlisted; they are not universal guarantees for every product.
| Reference configuration | Weighing arrangement | Verified range and hopper information | Speed and accuracy reference | Conditions that still need confirming |
|---|---|---|---|---|
| Lancing LU-999 Compact floor-standing vibratory weigh filler | Vibratory product feed into an electronic weighing system, then discharge to an operator-presented pack. | 10–999 g reference range. Hopper approximately 280 × 280 × 270 mm. | 6–15 bags/minute and approximately ±2 g in the verified reference specification. | Material flow, particle size, dose, hopper level, container handling and representative product trials. |
| Lancing LU-GFKL420 Automatic VFFS line | Ten electronic weighing heads feeding a roll-film vertical form-fill-seal machine. | 10–2500 g reference range; quoted for 500 g to 1 kg bags. Approximately 1.3 L per weigh head. | 5–60 bags/minute and approximately ≤0.3–1 g in the verified reference specification. | Product, target weight, bag former, bag dimensions, film, seal format, product drop and witnessed sample trials. |
| CBW-3000T2 / CBW-5000T2 Recorded Lancing weigh/depositor routes | Two-head semi-automatic weigh/depositor model references. | 3000 g and 5000 g model designations recorded in first-party equipment data. | Output and tolerance are deliberately not stated here because a verified test basis was not supplied for these model records. | Product sample, target range, operator presentation, discharge arrangement and agreed acceptance test. |
The correct quotation should state the exact product and pack used for any output or accuracy figure. Similar-looking powders, granules and pieces can behave differently because of bulk density, particle distribution, moisture, static, dust, fragility and hopper refill conditions.
Trial and acceptance method
Measure the distribution, not one successful fill.
- Define the test basis. Agree the product lot, target weight, pack, hopper level, feed method, machine settings and intended production rate.
- Stabilise the process. Zero or tare the weighing system, verify the reference scale or test weights, run enough product to reach normal operating conditions and record any warm-up or settling period.
- Collect consecutive results. Weigh an agreed sequence of normal production fills rather than selecting only good packs. Record net weight, rejects, stoppages and visible product damage.
- Calculate useful statistics. Report the mean, sample standard deviation, minimum, maximum, range, under-target count and the proportion within the agreed tolerance.
- Record output under the same conditions. Packs per minute should include the real bag, pouch or container handling route and should identify whether refilling, sealing, checkweighing or operator presentation was the bottleneck.
- Document cleaning and changeover. Note product-retention points, tools required, access to contact parts, reassembly checks and the settings or recipes needed after changeover.
Giveaway, calibration and legal metrology.
Average giveaway is the mean accepted net weight minus the agreed target or declared quantity. Estimated run giveaway is that average multiplied by the number of accepted packs, using consistent units.
Calibration and routine verification help control measurement drift, but they do not by themselves establish that an instrument is suitable for a regulated trade use. The intended use, instrument category and applicable conformity route must be confirmed separately.
UK packaged-goods rules place responsibility on the packer. Official guidance explains the average-quantity rules, including the mean, tolerable negative error and the prohibition on packs below twice that error.
Page ownership
Use the specialist Lancing site when another technology owns the question.
WeighFillers.co.uk is focused on weight-based dosing, target-weight control, linear and multihead weighing, semi-automatic weigh/depositing and the interface between weighing and the finished packing line. It should not duplicate detailed specialist content already owned by another Lancing domain.
- Use Combiweigh for the broader combination and linear-weigher range.
- Use Powder Fillers or Auger Fillers when powder flow, auger tooling and powder-specific cleaning are the primary decision.
- Use Form Fill & Seal for the detailed reel-fed VFFS machine and film-forming route.
- Use Pouch Fillers for premade pouch opening, filling and sealing.
- Use Lancing UK for a broader filling, capping, labelling or complete packaging-line project.
Buyer questions answered from the test basis.
What evidence should support a weigh filler accuracy claim?
Record the product, target weight, feeder settings, hopper condition, pack presentation, sample size, mean net weight, standard deviation, minimum, maximum and any rejected packs. A single best fill is not a useful acceptance result.
How is average product giveaway calculated?
For an agreed target or declared quantity, average giveaway is the mean accepted net weight minus that reference quantity. Estimated giveaway for a run is the average giveaway multiplied by the number of accepted packs, using consistent units.
Does calibration make a weigh filler legal for trade?
Not automatically. Calibration supports measurement control, but legal-for-trade suitability depends on the instrument, its intended use and the applicable legal-metrology route. The packer remains responsible for packaged-goods compliance.
Where should a checkweigher sit in the line?
It normally checks the finished pack after filling and closing or sealing, where the final net quantity can be assessed. Pack spacing, belt speed, reject handling and line-stop signals must be agreed with the rest of the line.
What samples are needed before a quotation?
Provide representative product, the smallest and largest target weights, the actual bag, pouch or container, film where relevant, and enough product to observe normal flow, dust, fragility and changeover behaviour.
