Weighing & Counting Packing Machines
MIQI MQ-CP-35 is a weighing and counting packing platform for suitable hardware and small parts. The published specification lists 200 g–5 kg per bag, 0.5–10 g weighing accuracy, 4–6 bags/min, a 5 L hopper, PLC control and 500 preset programs. These figures describe the listed platform; the achievable count, feed rate and finished pack depend on the parts and agreed configuration. Review piece-weight variation, feeding, bag format and sealing requirements with representative samples.
A weighing and counting packing machine prepares a dose by weight or an agreed counting method before packaging. Counting by weight estimates quantity from net batch weight and average piece weight. It does not prove the identity or exact quantity of every component in a mixed kit.

How Counting and Weighing Packing Works
Characterize the parts
Measure representative piece weights and inspect geometry, surface condition and variation across batches. Define whether the purchase requirement is bag weight or verified piece count.
Choose feeding and dosing
Review hopper feeding, bridging, tangling and dose control with samples. Confirm how the selected arrangement counts or weighs the parts and handles an incomplete dose.
Define bagging and sealing
Agree bag material, size, presentation and the filling/sealing sequence. A listed weighing range does not establish compatibility with every film or bag format.
Test finished packs
Compare actual contents and net weights with the target, then record output, reject/rework decisions and changeover settings. Include downstream inspection or labeling only when specified.
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.
How to Specify a Parts Weighing and Counting Packer
Weight dosing or exact piece count?
For parts of consistent mass, weight dosing may estimate a useful count. If exact count is essential, confirm the counting method and test worst-case piece-weight variation; a weighing tolerance alone cannot guarantee one-piece detection.
Single component or mixed hardware kit?
Different parts can have similar total mass. Separate feeding, counting or presence checks may be needed for mixed kits. Send the bill of materials and real assemblies for review.
Flow, tangling and bag format
Long screws, hooked parts and oily components may bridge or tangle. Test the whole flow from hopper to bag, including seal contamination and product damage.
Evidence for the quoted output
Specify bags per minute, target quantity, refill and changeover conditions together. Agree sample size and acceptable over/under count before evaluating a trial.
Weighing and Counting Applications
Fastener bags
Assess screws, nuts or anchors of one defined type using representative piece-weight samples and the target bag quantity.
Service kits
Review mixed-component kits for separate counting or presence verification; total mass alone may hide a wrong component.
Furniture fittings
Define the full bill of materials, allowable quantity variation and a way to verify the completed kit.
Hardware repacking
Confirm feed behavior, bag dimensions, sealing and finished-pack inspection before specifying a semi-automatic or integrated cell.

Frequently Asked Questions
Can weighing guarantee an exact number of screws?+
Not from the weighing accuracy alone. Count-by-weight depends on average piece weight, its variation and measurement uncertainty. For an exact count requirement, validate the selected counting method with actual parts and deliberately short or overfilled samples.
Can MQ-CP-35 pack mixed parts automatically?+
Mixed-kit suitability must be reviewed. The number of feed streams, counting method, component identification and bagging sequence need a documented configuration; the catalogue specification does not prove every mixed-kit combination.
What is included in a packing line quotation?+
Define the feeder, dosing or counting stage, bag presentation, sealing, coding, inspection and operator tasks separately. Include the interface and fault-handling responsibility for any additional equipment.
What samples should I send?+
Send typical and extreme parts from more than one batch, the target count or weight, filled and empty bags, the required output and examples of acceptable and defective packs.
Is a downstream checkweigher enough to verify kit completeness?+
It can identify weight differences only when they remain distinguishable from normal component and packaging variation. Wrong parts with similar mass may require an additional verification method.
