Startup Yield Loss
Quality
Startup Yield Loss
OEE quality loss caused by scrap or reduced yield during startup, changeover or warm-up.
Examples
- 01After each colour change on the extruder, the first 25 minutes produce off-colour material, which is counted as startup yield loss.
- 02The OEE review compares startup yield loss by product and shows that light colours after dark ones cause the highest loss.
- 03A new purge procedure and a fixed colour sequence cut startup yield loss from 25 to 10 minutes per changeover.
