Weighing & Counting Packing Machines
A weighing and counting packing machine doses product into bags by target weight or piece count, closing the gap between bulk product and sealed, labeled packs. MIQI's MQ-CP-35 packs hardware, fasteners, and similar parts into bags of 200 g to 5 kg at 0.5-10 g weighing accuracy and 4-6 bags/min, fed from a 5 L hopper and driven by PLC control with 500 preset programs on a 10-inch color touchscreen. The machine anchors a complete packing cell: upstream feeding, weigh-count verification, bagging, and downstream labeling and coding are configured as one line, so a fastener or component maker replaces several manual stations with one operator. Like all MIQI equipment it is sold factory-direct from Guangdong, with program setup, spare parts, and integration support coming from the manufacturer rather than a reseller.
A weighing and counting packaging machine is equipment that dispenses a preset weight or piece count of product into each bag or container, verifies the dose by weighing, and completes the pack automatically. It combines a feeding system, a weighing hopper, and bagging hardware under one PLC, so quantity accuracy is enforced by measurement rather than operator judgment. These machines are standard for hardware kits, fasteners, and granular products where every pack must contain exactly the stated quantity.

Weighing and Counting Packer Comparison
| Model | Single-Bag Range | Weighing Accuracy | Max Speed | Control |
|---|---|---|---|---|
| MQ-CP-35 | 200 g-5 kg | 0.5-10 g | 4-6 bags/min | PLC, 500 preset programs, 10-inch touchscreen |
Packing Machine Price Factors
Weighing and counting packing machine price depends on component mix, target bag weight or count, feeding and counting method, bag material and size, required speed, coding and sealing functions, and the level of operator involvement. Mixed hardware should be tested because part geometry and tangling can control the real output more than the nominal weighing range.
Weighing and Counting Applications
Fastener manufacturing
Screws, nuts, and anchors are weigh-counted into retail and trade bags of 200 g to 5 kg, with gram-level verification replacing manual counting.
Automotive components
Service kits and small-part assortments are packed to exact counts, with 500 stored programs covering wide product catalogs.
Furniture and fitting kits
Flat-pack hardware sets are dosed by weight so a missing fitting is caught at the packing stage rather than at the customer's door.
Construction hardware and e-commerce
Bulk hardware is converted into labeled, sealed consumer packs on one line, from hopper feed to finished bag at 4-6 bags/min.

Frequently Asked Questions
How does a weighing and counting packing machine ensure count accuracy?+
The machine converts count into weight: with a stable known piece weight, a target count becomes a target weight, and the weighing system doses and verifies each bag against it. The MQ-CP-35 holds 0.5-10 g weighing accuracy across its 200 g to 5 kg range, so for typical fasteners the tolerance is tighter than one piece, meaning a bag short or over by a single item is detected. Programs store each product's piece weight, target, and tolerances, and 500 presets let mixed-catalog operations switch products from the 10-inch touchscreen without re-entry. For parts with variable piece weight, tolerance bands are set from measured piece-weight distribution during commissioning.
What does a complete packing line from MIQI include?+
A complete line built around the MQ-CP-35 covers feeding, weigh-count dosing, bagging, and finishing in one integrated flow: bulk parts load into the 5 L hopper, the weighing system doses each bag, and downstream stations seal, label, and code the finished packs. Because MIQI also manufactures checkweighers, weigh-price labelers, and inkjet-integrated conveyors, the verification and marking stages come from the same factory and share one control philosophy and one service contact. Lines are configured to the product: bag formats, speed targets around the machine's 4-6 bags/min dosing rate, and any re-check weighing stage are fixed during the specification review before quotation.
