Why Choose MQ-CWP6
±0.02g accuracy for gram-level packs
With ±0.02-0.05g checkweighing accuracy and a 0.1-100g weighing range, this checkweigher is purpose-built for stick packs of granules and reagent strips weighing just a few grams. A 3g coffee stick underfilled by 0.05g shows up on screen instantly — a weight difference no human hand could ever feel.
Multi-lane inspection that keeps pace
Lane count and lane pitch are customized to match your multi-lane packaging machine's discharge layout — one weighing platform per lane, with 100% inline inspection at 40-50 cuts/min, pack by pack. No merging lanes into a single file, no slowing the line, no retrofit: it connects straight to the outfeed of your packaging machine and runs.
Anti-interference design, stable on the shop floor
Vibration and air currents are the enemies of dynamic weighing. A special structural design effectively shields against external interference — with the packaging machine shaking next door and fans blowing overhead, gram-level readings hold steady. This accuracy is proven under real production conditions, not just laboratory numbers.
Load cell survives hundreds of times its range
A specially designed overload protection device keeps the load cell undamaged even when loads reach hundreds of times the weighing range, with accuracy fully preserved. A cleaner leaning on the platform or a dropped wrench would mean a destroyed load cell and line downtime on other machines — this one powers up and weighs accurately as usual.
300,000 traceable records, audit-ready
The machine stores 300,000 traceable weight records internally, with one-click export of production data to a USB drive. When a customer audit or market-surveillance inspection asks for net-content records of a specific batch, just hand over the USB — no digging through handwritten sampling sheets, no batch numbers that don't match the handwriting.
100 preset recipes, changeover without re-setup
Store up to 100 product recipes and simply recall the right one at changeover — no re-entering parameters item by item. On high-mix, small-batch stick-pack lines where two or three changeovers a day are the norm, every minute saved on changeover goes straight back into output.
Problems It Solves for You
A multi-lane packaging machine discharges 6 or 8 lanes of stick packs at once, but manual sampling only checks a few. When a worn dosing screw makes one entire lane run light, you often find out only after customers complain about short net content and retailers issue fines
Synchronized 100% inline inspection across all lanes weighs and logs every single pack. Any lane drifting off-weight shows up in the data immediately, so the shift crew can stop and investigate the same day — not after the whole batch has left the factory
Stick packs weigh only a few grams, and ordinary ±0.1g checkweighers simply cannot see filling deviations at that scale — out-of-tolerance packs ship mixed in with good ones while the line crew fights the equipment daily
±0.02-0.05g checkweighing accuracy across the 0.1-100g range is a spec defined precisely for gram-level stick packs. Deviations of tens of milligrams are measured reliably, giving you a solid basis for rejection and correction
Pharma and food plants are asked for net-content weight records during audits, but manual sampling sheets are incomplete and handwriting doesn't match batch numbers — leaving you exposed on the audit floor
300,000 traceable weight records stored on the machine and exported to USB in one click; these records can support the facility's documented GMP and audit procedures
A cleaner pressed down on the weighing platform, the overloaded load cell failed, and replacement plus recalibration cost two days of downtime — in peak season the lost output cost far more than the spare part
The overload protection device keeps the load cell undamaged under loads hundreds of times the weighing range, so everyday knocks and accidental pressure no longer take the line down

Functions in Detail
Multi-lane structure and customization
Lane count and lane pitch are built to match your multi-lane packaging machine's discharge layout — as many lanes out, as many weighing platforms in, with each stick pack landing on its own platform for individual weighing. No merging into a single file. Belt speed of 40-50 cuts/min matches mainstream multi-lane packaging machine cycles, and the special structural design shields against vibration, airflow and other interference to keep dynamic weighing stable under shop-floor conditions.
Data management and traceability
The machine stores 300,000 traceable weight records, with one-click export to USB for factory audits, net-content metrology inspections and upstream filling-accuracy analysis. Up to 100 product recipes can be preset and recalled at changeover, so high-mix lines never start setup from scratch. Historical data and recipes are managed separately and never interfere with each other.
Cleaning and maintenance
The machine is designed for easy disassembly and convenient cleaning — fast line clearance at changeover helps control cross-contamination, and the simplified structure reduces residue traps. The load cell carries a specially designed overload protection device. Confirm cleaning methods, materials and the installed configuration against the facility's own GMP procedures.
Operator interface
Operation is intuitive, with multi-language screens switchable in one touch and target information visible at a glance — a real boost to operating efficiency. New hires handle daily operation after brief training, reducing dependence on skilled technicians and keeping shift handovers smooth. Foreign staff and overseas plants can operate directly in their native language.
Installation and line integration
The product discharge platform adjusts from 270-750mm in height to align directly with your multi-lane packaging machine's outfeed, and conveyor belt length is customized to the space on site — retrofitting an existing line needs no major layout changes. At 40-50 cuts/min the belt runs in sync with the line: connect it and it simply becomes the next station after the packaging machine, with no dedicated line modifications.
Industries & Application Scenarios
Stick packs of granules and powders are checkweighed one by one at the multi-lane packaging machine outfeed. Missing-fill and empty packs surface in the weight data, and archived net-content records can support the facility's documented GMP traceability procedures
Reagent strips and test strips are weighed inline after packaging. ±0.02g-level weight differences identify empty pouches and strips missing membranes; out-of-spec data is available within the shift, so defective units stop quietly reaching end users
Stick-pack coffee, milk-tea powder and protein powder are checkweighed in sync after high-speed multi-lane filling. Dosing-screw drift on any single lane is caught and corrected within the shift — no more waiting for stocktake to reconcile the loss
Stick packs of powdered sugar, seasonings and meal-replacement powder go straight from the packaging machine over the scale. Light packs are pulled out by the data before shipment, cutting retailer net-content complaints and fines
Probiotic powder and collagen peptide stick packs run in high-mix production with recipe-based changeovers. 100 preset recipes support small batches and frequent product switches without re-entering parameters each time
Mask powder and travel-size care-product sachets are checkweighed inline. Paired with the multi-lane packaging machine, it safeguards fill consistency of promotional gift packs — so short-filled freebies never dent your brand

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.
