Why Choose MQ-CW3523T1
From ±0.02g — one missing screw sets off the alarm
Display resolution 0.01g, dynamic checkweighing accuracy ±0.02-0.1g. A brick set short one small piece or a kit missing a single nut — that tiny weight difference gets caught in one pass down the belt, with no reliance on eyes or feel.
Forward/reverse sorting, no air supply required
Good products pass through as the belt runs forward; rejects are carried back out as the belt reverses. Rejection is done by the belt itself — no air compressor, no pneumatic pusher. Light, small items never get blown away or knocked off course, and stations without compressed air can go straight online.
1-1000g range — small bags to full boxes on one machine
Checkweighing range 1-1000g, for products up to 300mm long and 200mm wide. Small hardware sachets, single brick boxes and loose accessory packs all fit this window, so one machine covers multiple SKUs — no buying separate equipment per product.
100 recipes, changeover without stopping the line
Stores 100 product recipes with 10 quick-access menus on the touchscreen. Switching products takes one tap — the belt keeps running and the line never stops. With multi-SKU, small-batch scheduling, there is no need to reserve dedicated downtime for setup.
304 stainless steel body, IP65 protection
Full 304 stainless steel housing rated IP65 keeps working in dust and moisture. Metal dust in hardware workshops and splash at washing stations pose no threat to the electricals, and the body stays rust-free for years.
Feedback signal links to the upstream packer
The machine outputs a production trend feedback signal: when weights start to drift, the upstream packaging machine can adjust its fill accordingly. Instead of reworking a bad batch after the fact, the deviation is pulled back at the trend stage — saving material and rework hours.
Problems It Solves for You
Brick sets rely on manual spot-count checks; a set missing one small piece is impossible to feel by hand, and once it reaches an e-commerce customer it means bad reviews, returns and customer-service compensation.
±0.02-0.1g dynamic accuracy enables 100% inline inspection — every box is weighed, missing or extra parts are judged by weight difference and reversed out, so defects never leave the workshop.
Hardware kits get a low manual sampling rate; when a customer finds one missing nut on their line, the whole batch comes back plus sorting and rework charges.
Pack-by-pack checkweighing at 1-35 packs/min turns sampling into 100% inspection. With USB data export, every batch's inspection records can be pulled up — documented evidence when settling matters with customers.
Pneumatic rejection blows light items over, off course or even bursts packs open — and you have to run a dedicated compressed-air line just for the scale.
Forward/reverse sorting rejects using the belt direction itself: products exit smoothly, no flipping, no scattering. Just connect AC220V±10% power to start up — no air-line retrofit needed.
Five or six product changes a day, each stopping the line 10-plus minutes for parameter tuning — the more small-batch orders, the more capacity gets eaten.
100 pre-stored recipes with 10 quick menus for one-tap recall; changeovers happen without stopping the machine, taking setup time out of the line cycle entirely.

Functions in Detail
How forward/reverse sorting rejects
The weighing section weighs each passing product in real time. If the weight is within tolerance, the belt runs forward and the product moves on to the next process; if judged out of spec, the belt reverses and carries the product back out toward the infeed side to the reject position. The entire reject action is performed by the belt motor — no cylinder, no pusher — making it especially gentle on light, small or tip-prone products. One weighing section is standard; a 2-section option supports higher line speeds.
Data management and traceability
Checkweighing data exports via USB — pass counts, reject counts and weight distribution per batch can be copied out for archiving or handed to customers for verification. Options include real-time printing, inline barcode reading, code-based sorting, inline inkjet coding and inline labeling, binding weight results to product barcodes so each item carries its own record, traceable by code to the exact batch.
Cleaning and routine maintenance
The belt uses a quick-release buckle design — swap it without tools or frame disassembly: slide the old belt out and clip the new one on. For daily cleaning, taking the belt off to rinse and wipe is quick work. The 304 stainless housing with IP65 protection keeps the electricals unaffected by dust and moisture, reducing environment-related downtime.
Changeover and recipe management
Touchscreen HMI with wizard-guided parameter setup. 100 product recipes are stored onboard, with frequently run products assigned to 10 quick menus — changeover is a tap on the screen while the belt keeps running. In mixed multi-SKU production, operators don't need to memorize parameters; they just tap the menu.
Installation and power requirements
The weighing section measures 350mm long by 230mm wide, for products up to 300mm long and 200mm wide — a compact fit into existing conveyor lines. Power is single-phase AC220V±10%: plug in at any ordinary workshop and run, no compressed air needed, keeping line-modification cost low.
Industries & Application Scenarios
Boxed brick sets are weighed whole after packing — one missing piece or an extra sticker sheet is judged by gram difference, and short boxes are reversed back for recheck, avoiding e-commerce bad reviews and platform missing-part compensation.
Screw, nut and washer sachets are weighed pack by pack off the line; the 1-1000g range covers gram-level sachets up to full boxes, with missing or extra pieces rejected on the spot — never let your customer's line do your inspection for you.
A flat-pack hardware kit holds dozens of pieces per bag; manual counting is slow and error-prone. Set a recipe against the standard weight and weigh every pack — no bag missing a single insert nut ever ships, cutting installation complaints.
Cable, connector and screw-pack bundles are checkweighed inline after bagging; with optional inline barcode reading and labeling, weight and barcode are matched one-to-one for fully traceable shipping records.
Injection-molded small parts are bagged by count — gram difference equals piece difference. Accuracy from ±0.02g stops both under- and over-fills, and light items are rejected smoothly by belt reversal, no blow-away, no burst bags.
Missing-part screening for pen refills, assembly stationery and small tool sets in combo packs; 10 quick menus handle multiple changeovers a day, keeping small-batch, multi-SKU schedules running without line stops.

Weight Grading vs Checkweighing vs Batching for Fish, Poultry and Seafood
A checkweigher decides whether a completed pack is within limits; a weight grader routes individual products into multiple weight classes; batching selects or combines pieces toward a pack target. Choosing the wrong function creates the wrong conveyor and yield strategy.
Checkweigher Reject Systems: Air Blast, Pusher, Flap, Arm, Wheel or Stop Alarm
The best checkweigher rejector is the one that removes the real product reliably at the real speed. Compare six mechanisms by product mass, stability, line rate, available air, hygiene and fail-safe confirmation requirements.
