PMMA Demolding Whitening
Fenómeno del problema
PMMA products whiten at ejection locations during demolding
Análisis de la causa
Ejection stress causes local crazing, and whitening is obvious in transparent parts; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
Solución
Enlarge and add ejector pins; sufficient draft angle; appropriately raise mold temperature; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Conclusión clave
Demolding whitening is solved by ejection equalization; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
