PVC Shoe Sole
Problembeschreibung
PVC injection-molded shoe soles deformed during demolding
Ursachenanalyse
Uneven wall thickness of the sole caused asynchronous cooling and deformation during demolding; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Lösung
Uniform wall thickness design; sufficient cooling; demolding and shaping fixture; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Wichtigste Erkenntnis
Sole deformation is controlled by wall thickness and cooling; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
