PVC Mold Temperature 30-50
Fenómeno del problema
PVC mold temperature set to 70℃, product dimensions unstable and demolding difficult
Análisis de la causa
Too high PVC mold temperature delays cooling and aggravates mold sticking, dimensions and demolding both affected; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based solely on experience.
Solución
PVC mold temperature controlled at 30-50℃; cooling water channels ensure flow; mold temperature machine ordinary water temperature machine suffices; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
PVC is a low mold temperature material, cooling efficiency first; 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 later
