High-Precision Multi-Lane Checkweigher for Stick Packs & Sachets

100% inline weight inspection at the speed of your packer — ±0.05 g accuracy, up to 400 packs per minute, zero underweight packs shipped.

Trust bar: ±0.05 g accuracy · 50 cuts/min per lane · 4–12 lanes · CE certified · Factory-direct

Run the numbers on your last shift. If your line produces 400 stick packs a minute and your QC team spot-checks 20 packs an hour, you are inspecting roughly 0.08% of your output. The other 99.92% ships on faith.

Faith is not a quality system. It is how overfill silently eats your margin — and how an underweight sachet reaches a retailer's shelf, where it becomes a chargeback, a consumer complaint, or a net-content audit under EU Directive 76/211/EEC or FDA labeling rules.

This machine replaces faith with data. Our high-precision multi-lane checkweigher weighs every pack on every lane, in real time, and ejects any pack outside your tolerance — overweight, underweight, or empty — before it reaches the case packer.

• ±0.05 g weighing accuracy on lightweight film packs

• Up to 50 cuts/min per lane, 400 packs/min machine total

• 100% inspection coverage — no sampling, no guessing

• Automatic rejection of out-of-tolerance and empty packs

• Lane-by-lane statistics that expose filler drift before it becomes giveaway

Key features — what makes this checkweigher pay for itself

Six engineering choices that turn a weighing scale into a margin-protection system.

±0.05 g precision on lightweight film packs

High-resolution load cells with smart digital filtering cancel line vibration, so the spec-sheet accuracy holds on the factory floor — even on sub-10 g coffee sticks.

Benefit: tighter tolerances mean less safety overfill and lower giveaway.

True multi-lane throughput — up to 400 packs/min

Each lane weighs independently at 50 cuts/min; an 8-lane build delivers 400 packs/min without sacrificing accuracy.

Benefit: keeps pace with your stick packer, never becomes the bottleneck.

100% inline inspection, zero sampling

Every pack on every lane is weighed and logged — no spot checks, no statistical guesswork.

Benefit: full traceability for HACCP, GMP and e-mark / EU 76/211 compliance.

Automatic rejection of bad packs

Air-blast or mechanical diverter ejects overweight, underweight and empty packs without stopping the lane.

Benefit: no defective pack reaches the case packer or the customer.

Lane-by-lane statistics & filler-drift alerts

Per-lane weight trends surface auger drift early, before it turns into giveaway or rejects.

Benefit: recover 0.2–0.5 g per pack by tightening filler targets with confidence.

One-touch recipe changeover

Stored recipes recall belt speed, tolerance and reject settings per product. Switch from milk powder to coffee sticks in seconds.

Benefit: more uptime, fewer operator errors on multi-SKU lines.

Giveaway — the margin killer you can't see on the filler HMI

In powder packaging, fillers are deliberately set to overfill rather than risk underweight packs. That safety margin is giveaway, and on a milk powder stick line it quietly adds up to kilograms of product given away every shift.

If you have ever asked how to reduce giveaway in powder packaging, you have heard the standard answers: better auger servos, denser product handling, more frequent manual checks. They all help at the filler. None of them tell you what actually leaves the line.

This checkweigher closes the loop. With 100% pack-level weight data, you can tighten the filler's target from "safe" to "exact" — typically recovering 0.2–0.5 g per pack. On a 400-pack-per-minute line, the machine often pays for itself in months, before counting the rework and recalls it prevents.

How the high-speed checkweighing system works

Unlike a generic automatic weight checker machine retrofitted for small packs, this platform is engineered — from infeed to reject station — for lightweight, flexible formats:

1. Lane-synced infeed. Packs arrive from your stick packer in discrete lanes and are spaced for stable, vibration-free weighing.

2. Per-lane dynamic weighing. Precision load cells weigh every pack in motion; smart digital filtering cancels line vibration, so a ±0.05g precision checkweigher on the spec sheet stays ±0.05 g on the factory floor.

3. Instant decision & rejection. Out-of-tolerance packs are ejected by air blast or mechanical diverter — without stopping the lane.

4. Data you can audit. Lane statistics, reject counts and batch reports export directly into your HACCP, GMP and e-mark documentation.

This is not an industrial dynamic weighing scale adapted to sachets. It is a purpose-built multi-lane powder weighing machine — and the difference shows in the accuracy column.

Built for the formats you run today — and next year

Purpose-built as a checkweigher for stick pack and sachet formats, it covers:

H3: Stick packs & small sachets — back-seal and four-side-seal packs: milk powder sticks, coffee / 3-in-1 sticks, milk tea powder, protein powder, probiotic powder, meal-replacement and seasoning powders. As a milk powder sachet checkweighing system in the morning and a coffee stick packaging weight checker after lunch — recipe memory makes changeover a touchscreen tap, not a mechanic's visit.

H3: Granules & agglomerates — high accuracy granule checkweigher performance on free-flowing products: granules, effervescent and instant drink mixes.

H3: Film compatibility — aluminum foil laminates, aluminized films and pure plastic composite films, with no recalibration drama when you switch materials.

One platform across food, pharma & daily chemical

• Food: configured as a food grade automatic weight sorter with stainless contact parts and washdown-friendly design.

• Pharmaceutical: as a pharmaceutical multi-lane checkweigher, it supports GMP-aligned audit trails and user-level access control.

• Daily chemical: powder and granule sachets handled with the same stability and traceability.

Match your packer — not the other way around

Your stick packer defines the lanes; your checkweigher should agree. The standard build is an 8 lane high speed checkweigher delivering 400 packs/min — and we routinely engineer a compact 4-lane unit or a custom 12 lane checkweighing line to mirror your packer's output exactly.

A true custom checkweighing solution for packaging line integration means:

• Infeed pitch and belt width matched to your pack dimensions

• Lane count and speed synchronized with your packer

• Reject device selected for your format (air blast for light sticks, diverter for heavier sachets)

• Height, footprint and HMI position adapted to your floor plan

Direct from the manufacturer — what you actually get

Searching for a multi-lane checkweigher manufacturer in China returns hundreds of look-alike listings. Here is what buying from us includes:

• Factory-direct pricing — no trading-company margin baked in

• Free sample testing — send 20–50 packs; receive a recorded test report with measured accuracy at your target speed

• FAT at our factory on your product before shipment

• CE documentation, manuals and wearing-parts list

• Lifetime remote support; on-site commissioning available

Most "precision checkweigher for sale" listings quote a bare machine on a pallet. We quote a working inspection station — engineered, tested on your packs, and backed by a reliable sachet checkweigher supplier relationship that continues long after installation.

Pricing without the guesswork

Checkweigher pricing depends on lane count, pack size, rejection type and integration scope — which is why fixed online numbers are usually misleading. Instead, request our high speed checkweigher price list: send your pack sample and packer model, and you receive an itemized, lane-by-lane quotation within 24 hours. Not a "contact us" black hole.
