What are you filling?
Include product name, free-flowing or dusty behaviour, particle size, density if known, and whether samples are available.
Weigh filler specialists
Weigh filler enquiry checklist.
Use this checklist to send the product, target weight, pack style and output details needed for a useful weigh filling machine recommendation.
Use this checklist before asking Lancing for advice or a quote.
The more complete your brief, the easier it is to compare the right machine options. Product behaviour, target weight, pack type, output and line constraints are the details that usually make the biggest difference.
Minimum enquiry details
- Product name and product behaviour.
- Target fill weight range and tolerance.
- Pack format and fill opening.
- Required packs per minute or per hour.
- Manual, semi-automatic or automatic preference.
- Available footprint, utilities and existing equipment.
Briefing form
Copy these fields into the contact form.
These prompts reduce back-and-forth and make the first recommendation more useful.
What weight range?
Give minimum and maximum fills, tolerance expectations, giveaway sensitivity and pack-count range.
What happens after filling?
Explain whether the filled pack is sealed, capped, labelled, coded, checkweighed, conveyed or packed into cases.

Answers for buyers preparing a weigh filler enquiry.
Do I need every detail before contacting Lancing?
No. Send what you know. Product, target weight, pack type and desired output are enough to start a useful conversation.
Should I send product samples?
Samples are often helpful when product flow, dust, fragility or dosing behaviour may affect the machine route.
What if I am planning a future line rather than buying immediately?
Early planning is useful because line layout, utilities, pack format and future SKU range can affect the machinery decision.
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.
Quotation inputs
Use one evidence pack for machine selection, trial and acceptance.
A complete enquiry reduces assumptions and allows the same basis to follow the project from initial shortlist to factory acceptance.
| Information | What to send | Why Lancing needs it |
|---|---|---|
| Product | Name, composition, representative samples, bulk density, particle size, dust, static, fragility, moisture and batch variation. | Chooses the feeder, hopper, contact path and cleaning route. |
| Weights | Smallest, normal and largest target; declared quantity; tolerance; current giveaway or underweight problem. | Sizes the weighing path and defines the acceptance statistics. |
| Packs | Actual pouch, bag, jar, tub or bottle with dimensions, opening, film, seal or closure. | Defines product drop, support, clamp, former and downstream handling. |
| Output | Accepted finished packs per minute, hours per shift, batch size and operator plan. | Separates filler cycle from the real production-line requirement. |
| Line and controls | Layout, upstream feed, downstream machines, utilities, controls standard, coding and inspection. | Defines interfaces, buffers, conveyors, guarding and commissioning scope. |
| Cleaning | Product sequence, allergen/cross-contamination standard, cleaning method and changeover target. | Checks access, removable parts, tooling, drains or dust containment. |
| Acceptance | Sample size, mean, standard deviation, min/max, under-target rules, product damage, seal quality and output duration. | Prevents a vague “accuracy” or “speed” claim becoming the only test. |
Sample-trial protocol to attach.
- Identify the samples. Record product lot, pack and film references and confirm they represent normal production.
- Agree the run conditions. Define targets, hopper range, settings, operator tasks and downstream equipment.
- Agree the measurements. Use a suitable reference scale and record consecutive net weights, rejects and elapsed time.
- Agree acceptance before the run. State statistical, quality, output and clean-down criteria rather than judging retrospectively.
- Record deviations. Any setting change, refill, stop, jam or sample difference must remain in the trial record.
Files that improve a review.
- Product specification and safety data where applicable.
- Pack drawings, samples and film specification.
- Current line photos, video and dimensioned layout.
- Existing weight data or checkweigher export.
- Cleaning SOP and utilities schedule.
- URS, FAT or customer acceptance template.
Trial dossier
Turn product and pack samples into an auditable trial brief.
Sample quantity is not a fixed website specification. It should be sufficient to tune the machine, challenge the required weights, include refills and changeovers, and complete the agreed consecutive-fill run without substituting a different product lot.
| Trial input | Project-specific basis | What to record before dispatch | Why it matters |
|---|---|---|---|
| Product quantity | One supplied LU-3000C quotation requested 10–15 kg of representative product. Other projects may need more or less. | Batch or lot, date, moisture or conditioning, bulk density where known, fines, particle range and normal production variation. | The same sample must cover tuning, all targets, refill behaviour and the acceptance run. |
| Pouch quantity | The same quotation requested 25–50 empty pouches of each size. | Size reference, dimensions, laminate, zipper or closure, maximum usable opening and print/code position. | Allows outlet review, repeated filling, sealing trials, rejects and changeover without relying on one ideal pack. |
| Target matrix | Smallest, normal and largest production weights rather than one convenient test point. | Declared quantity, internal tolerance, current set-point, expected batch size and finished-pack output. | Feeder trim, weigh-hopper capacity, bulk volume and cycle time can change across the range. |
| Line interfaces | Manual pouch presentation, bag clamp, conveyor, premade-pouch machine, VFFS or rigid-container handling. | Layout, heights, line direction, ready/busy signals, coding, inspection and downstream stop behaviour. | Prevents a successful standalone dose from failing when connected to the real pack route. |
| Acceptance method | Agreed before the trial and tied to the intended product, pack and output. | Reference scale, tare method, consecutive sample size, mean, standard deviation, min/max, rejects, product loss and elapsed time. | Keeps the decision evidence-led and avoids selecting one favourable fill or short burst. |
Fields for the trial result sheet.
- Machine, software or recipe reference and all relevant settings.
- Product lot, pack reference, target weight and tare method.
- Reference-scale identification and verification status.
- Sequential fill number and net weight, including rejected or disturbed packs.
- Hopper level, refill, stop, adjustment, jam or operator intervention against the sequence.
- Mean, standard deviation, minimum, maximum, range and under-target count.
- Accepted finished packs, rejects, elapsed run time and actual finished-pack output.
- Product damage, loss, dust, retained material, seal contamination and cleaning observations.
Keep samples representative.
Do not sieve out normal fines, dry a moisture-sensitive product unusually, use laboratory-perfect packs or omit the most difficult target unless that condition is excluded from the final specification. Record any difference between trial material and intended production.
Prototype pouches can support an early feasibility test, but production-quality laminate and dimensions are normally needed before outlet, sealing and sustained finished-pack acceptance are closed.
Buyer questions
Sample and acceptance questions.
Is 10–15 kg always enough for a weigh filler trial?
No. That was the requested basis for one supplied LU-3000C project. The required quantity depends on product, number of targets, hopper volume, line configuration, changeovers and the agreed acceptance run.
What makes a product sample representative?
It should reflect normal production particle size, fines, moisture, bulk density, fragility and batch variation. Any conditioning or difference from production should be declared.
Can prototype pouches be used?
They can support early feasibility work, but final outlet, pouch handling, sealing and finished-pack acceptance normally need production-quality packs with the intended dimensions and laminate.
What should be agreed before the acceptance run starts?
Agree product and pack references, targets, settings, hopper range, operator tasks, reference scale, consecutive sample size, statistics, reject rules, product-quality checks and finished-pack output.
