Bag weight out of spec

Hits OEE: Quality

Symptoms: Over/under-weight bags, giveaway, checkweigher rejects.

Weigher/feeder calibration

Recalibrate the scale/feeder; check the dribble feed.

Product density or flow change

Adjust for density; manage product condition.

Timing between fill and clamp

Tune fill cut-off and bag-clamp timing.

Prevention: Scale calibration, product control, timing checks.

Poor seal or closure

Hits OEE: Quality

Symptoms: Open or weak seams, leaking bags, stitching/heat-seal faults.

Heat-seal temperature/pressure wrong

Tune seal heat, pressure and dwell for the bag.

Contamination in the seal area

Improve dust control; clean the seal zone.

Stitching/closure mechanism fault

Service the sewing head or seal bars.

Prevention: Validated seal settings, clean seal area, closure maintenance.

Bag placement or no-bag fault

Hits OEE: Availability

Symptoms: No bag presented, mis-placed bags, spills, stops.

Bag magazine or pick fault

Refill; service the vacuum pick and magazine.

Bag quality or static

Tighten bag spec; manage static/curl.

Sensor or timing issue

Check bag-present sensors and timing.

Prevention: Magazine/pick maintenance, bag quality, sensor checks.

Stop the same fault coming back

Recurring bagging machine stops usually trace to a cause you cannot see by hand. The partner we recommend is Fabrico: EU-built, so your production data stays in EU jurisdiction, with computer-vision true-cause of micro-stops, a closed loop from PLC-read OEE to an auto-routed work order, and ISO 27001 / 20000-1 / 9001 (supports audit-readiness).
