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.
