Checkweigher Videos: 54 Real Machine Demonstrations
This page collects 54 checkweigher demonstration videos filmed on real MIQI machines — dynamic checkweighers, weight sorters, metal detector combos and custom builds — weighing real products from 1.56 g sachets to 60 kg logistics loads. Every weight reading shown on screen is a genuine HMI reading, not an animation.
Use this page to see how a checkweigher works before you buy one: reject mechanisms firing in real time, live accuracy statistics, factory floor footage and installed customer lines. Every video links to the machine series it shows.
Reject Systems in Action
What actually happens to a bad pack. These clips show pneumatic pusher rejects, collection bins, and underweight / overweight alarms firing on live product — the checkweigher reject demonstration most datasheets only describe in words. If you are comparing air blast vs pusher vs drop flap rejection, start here.

Accuracy & Live Statistics
Checkweigher accuracy testing videos with the HMI screen readable: repeatability runs, batch statistics, pass rates and spreads. The standout is a 60 kg load weighed 122 consecutive times with only 15 grams of spread at 90 m/min — the kind of dynamic weighing accuracy proof we send after every free sample test.

Heavy Cartons & Logistics
Roller checkweighers and DWS logistics scales handling 8-22 kg cartons, crates and strapped export cases, plus installed warehouse lines with 90° and 180° conveyor curves. If your question is how to weigh every carton at goods-out without stopping the flow, these videos answer it.

Combos & Custom Builds
A checkweigher + metal detector combination on one frame, enclosed inspection conveyors on customer sites, and purpose-built guarded modules for products that will not sit on a flat belt. When a catalogue machine does not fit, this is what we build instead.

Questions buyers ask about these videos
Can I get a video of my own product running on the machine before I order?+
Yes — that is exactly how we sell. Send us your product, pack format, line speed and target tolerance. We run it on the actual machine and send you a video like the ones on this page, together with the batch statistics — including the honest cases where your tolerance is not achievable at your speed. The sample test is free. WhatsApp +86 152 1890 9599 or 897874196@qq.com.
Are the weight readings in these videos real?+
Every reading is the live HMI display of the machine on camera — nothing is simulated or edited in. Several clips are deliberate screen recordings so you can read the full statistics panel: accept band, max, min, average, batch total and pass rate. That is the same data export (USB) you would use for BRCGS or HACCP records.
How does a checkweigher reject a bad pack without stopping the line?+
The controller times each pack from the weighing belt to the reject point and fires the actuator at exactly the right moment — an air blast for light sachets, a pusher rod for boxes, a swing arm for high speed flows, or a drop flap for small items. Several videos on this page show the pusher firing and the pack landing in a closed collection bin.
What accuracy do these machines actually achieve?+
Depends on class: multi-lane and pharma machines reach ±0.02-0.1 g, food-line machines ±0.3-3 g, heavy carton and logistics machines ±5-30 g. Watch the repeatability video: 122 consecutive weighings of a 60 kg load within a 15 g spread at 90 m/min belt speed. Accuracy claims only mean something at your line speed with your product — which is why we test yours first.
Do you ship these machines outside China? What about support?+
Yes — worldwide export, factory-direct from Guangdong. 2-year warranty with lifetime technical support; commissioning is guided by video call, and spare parts ship from the factory that built the machine. Every machine is tested on video before dispatch, so you see your unit running before it leaves the floor.
Which video should I watch if I only have two minutes?+
Watch 'Checkweigher Rejecting Underweight Packs in Real Time' for the complete weigh-judge-reject cycle at ±0.02 g division, then '60 kg Weighed 122 Times' for repeatability proof at the top of the range. Together they cover the two questions that matter: does it catch bad packs, and can you trust the numbers.
