Why Choose MQ-CWG6
±0.02g-class accuracy on every stick
With ±0.02-0.05g checkweighing accuracy across a 0.1-100g range, a stick pack underfilled by even a fraction of a gram gets caught on its first pass down the belt. A purpose-engineered structure shields the load cells from line vibration and air currents, so dynamic weighing results hold up under review — not just lab-bench static numbers.
Multi-lane weighing, matched to your packer
Lane count, lane pitch and conveyor length are all customized to your multi-lane packaging machine, with each lane running at 40-60 sticks/min — throughput scales with every lane you add. The discharge table height adjusts from 270-750mm, so the machine rolls right up to your packer's outlet and takes product directly. No line modifications to accommodate the checkweigher.
100 recipe presets, painless changeovers
Store up to 100 product recipes. When you switch formats, just recall the matching recipe on screen and start running — no re-weighing trials, no resetting limits every time. For stick-pack lines that change products several times a day, the setup time saved converts straight into output.
300,000-record traceability, audit-ready
The machine retains up to 300,000 traceable weight records, exportable to a USB drive with one tap. When a GMP audit or customer inspection asks for piece-by-piece weight records of a specific batch, plug in a USB drive and export — no manual log sheets, no after-the-fact backfilling. Your records stand up on authenticity and completeness.
Hygienic design with easy teardown cleaning
Product-contact parts strip down easily and clean fast. At batch changeover, line operators can dismantle, wash and reassemble them without waiting on maintenance, shortening cleardown time and helping the facility document its own cleaning and GMP procedures. Suitability must be verified for the installed configuration.
Multilingual UI new operators master in a shift
An intuitive operating screen with one-touch language switching shows the active recipe, pass count and reject count at a glance. No dedicated equipment specialist needed — regular operators handle daily changeovers and data checks after a brief handover, lifting operating efficiency measurably.
Problems It Solves for You
A multi-lane packer turns out hundreds of sticks a minute, and manual spot checks can't keep up. Underfilled or empty stick packs reach the market — at best a customer complaint and payout, at worst a failed regulatory inspection and a full batch recall.
The MQ-CWG6 is built with lanes matching your packer, inspecting every single stick inline at 40-60 sticks/min per lane. With ±0.02-0.05g accuracy, underweight packs are intercepted before they ever leave the plant — spot checks become 100% inspection.
Stick-pack lines switch formats several times a day, and every changeover means fresh weighing trials and limit resets — half an hour of downtime each time, eating a big chunk of the shift's output.
With 100 product recipes on board, changeover is just recalling the right recipe on screen. Target weight and limits load with the recipe, eliminating the trial-weighing and reparameterizing grind at every format change.
A GMP audit or customer inspection demands piece-by-piece weight records for a specific batch. Manual log sheets are incomplete or backfilled after the fact, and the audit ends with a data-integrity finding.
300,000 traceable weight records live in the machine, exportable by batch to USB in one step. Piece-level weight records are available on demand, with data integrity that stands up to any audit.
Every multi-lane packer differs in lane count, lane pitch and discharge height. A standard checkweigher won't line up with the outlet, forcing a transfer conveyor — one more drop point that degrades accuracy.
Lane count, lane pitch and belt length are customized to your packer's specifications, with table height set anywhere from 270-750mm. The machine docks directly to the discharge outlet — no transfer stages added.

Functions in Detail
Scraper-type multi-lane weighing structure
The machine mirrors your multi-lane packer's discharge layout with parallel lanes; stick products enter their own weighing sections for dynamic weighing. A purpose-engineered structure effectively isolates vibration, air currents and other external interference, so ±0.02-0.05g accuracy holds under real shop-floor conditions — not just demo-unit figures.
Data management and traceability
100 product recipe presets cover day-to-day switching across stick-pack formats. The machine retains 300,000 traceable weight records, including piece-level results and pass/fail judgments. One-touch export to USB feeds QC reports or audit submissions, eliminating the omissions and errors of manual transcription.
Cleaning and maintenance
Designed with product-contact parts that detach easily and clean fast. At batch changeover, the on-shift operator handles teardown, washing and reassembly, cutting cleardown waits. The simple structure also means fewer daily inspection points and can support the facility's documented cleaning and GMP procedures.
Operator interface
An intuitive screen with one-touch multilingual switching presents recipe recall, limit settings, output and reject statistics in one view. New staff run shifts independently after brief training, reducing reliance on dedicated equipment specialists and markedly improving operating efficiency.
Installation and customization
Lane count, lane pitch and conveyor belt length are all built to your on-site packer's specifications, with the discharge table height fixed within 270-750mm to meet your multi-lane packer's outlet flush. Provide your packer model and discharge layout at order time; the factory configures to drawing, and the machine installs and runs on arrival.
Industries & Application Scenarios
Docked to multi-lane stick packaging machines for 100% inline fill-weight inspection of stick tubes and granule sachets. Listed ±0.02-0.05g accuracy and 300,000-record traceability can support a facility's documented net-content and GMP procedures; actual suitability must be verified with the product and line speed.
Probiotic powders, collagen peptides and similar stick packs often carry just 1-5g per stick, where fill deviation directly undermines label claims. A range starting from 0.1g covers these lightweight packs, catching underfills and empties stick by stick.
Instant coffee sticks and milk-tea powder sachets dose at high speed on multi-lane machines, where powder-flow variation causes fills to drift high and low. Multi-lane simultaneous weighing monitors every lane's fill in real time — a drifting lane shows up at a glance.
Stick candies, chocolate bars, meal-replacement bars and other individually wrapped items within the 0.1-100g range are weighed piece by piece, with short-count, broken or underfilled packs rejected before shipment — cutting retail-end complaints.
Shampoo and mask-essence sachet samplers filled on multi-lane machines occasionally suffer product-in-seal and short fills. Piece-by-piece checkweighing intercepts defective sachets before cartoning, avoiding whole-box reinspection and rework.

Decoding Checkweigher Accuracy: What "±0.1 g" Actually Means (Sigma Conventions and How to Compare Vendors)
When a checkweigher datasheet says "±0.1 g", that number is meaningless on its own. Accuracy on a dynamic checkweigher is a statistical statement about a distribution of readings, not a hard boundary — and vendors do not use the same statistical convention when they print it. Some quote one standard deviation (1σ, roughly 84% of readings on one side of the distribution); others quote three (3σ, roughly 99.7% coverage). The same machine, the same belt, the same product can be advertised with very different-looking numbers depending on which convention the marketing department picked. This article explains the difference between display division and weighing accuracy — two promises that buyers routinely confuse — walks through what a sigma convention actually commits a vendor to, corrects the most common misconceptions in cross-border checkweigher procurement, and gives you a printable checklist of questions to run against any quotation. It also publishes the real, unrounded specification of the MIQI MQ-CW3512L1 tablet checkweigher as a worked example of what a transparent datasheet should contain.
How Does a Checkweigher Work? Infeed, Dynamic Weighing and Automatic Rejection
A dynamic checkweigher weighs every moving pack, compares the filtered result with recipe limits and removes or records exceptions. This engineering guide explains the complete three-stage process, the load-cell signal chain and the line conditions that determine repeatability.
Checkweigher Calibration and Dynamic Verification: A Practical Line Test
Calibration establishes the relationship between indication and reference mass; verification checks whether the complete checkweigher still performs acceptably in production. Use this repeatable workflow to test multiple weights, speeds and reject outcomes without confusing resolution with accuracy.
