A rise in a run's curve may become visible at the last stops. Review time, stop order and remaining load together to find a recurring pattern; it does not show cause alone.
Finding the break
For each run, record the slope-change time and stop number. If stop order changed, match the same physical location too.
Possible causes
- Plate use or condition can be reviewed.
- Compare lid-opening count and open duration.
- Record remaining load and product quantity.
- Time of day and outside conditions can vary.
Telling which it is
Compare runs under similar conditions; if the break moves when order changes, sequence is a candidate to investigate. Note condition differences; do not infer from one correlation.
The thermal mass effect
As load falls, contents and empty volume change. Record remaining load and arrangement; the curve alone does not prove a thermal cause.
Where the curve breaks is where the run plan meets physics.
What it means for planning
Assess a proposed sequence, load or equipment change separately. Use the same measures before and after a trial; product decisions belong to the authorized quality process.
Where the plate sits in an emptying container
Record arrangement, remaining product and model configuration. Follow the technical sheet and site SOP for plate placement; do not propose a new layout from the curve alone.
