PVDF Product Ejector Whitening
Fenómeno del problema
Whitening at the ejection position.
Análisis de la causa
Concentrated ejection force causes stress whitening; insufficient cooling causes a large shrink-fit force.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience; This mechanism has been repeatedly verified by industry materials, and it should be confirmed first during troubleshooting
Solución
①Increase the ejection area; ②extend cooling; ③balance ejection; ④ensure the draft angle.; After adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Conclusión clave
Ejector whitening is a stress signal; optimize the ejection system.; After confirming effectiveness, fix 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
