PVC Mold Temperature 30-50℃
Fenómeno del problema
Poor product surface gloss and roughness, or after mold temperature too high, cycle extended and deformation
Análisis de la causa
PVC mold temperature affects surface replication and stress: low mold temperature gives rough surface and poor gloss; rigid PVC mold temperature 30-50℃, soft 20-40℃; poor heat conduction needs sufficient cooling
Solución
①Rigid PVC mold temperature 30-50℃, soft 20-40℃; ②Cooling water channels ensure sufficient cooling; ③When surface requirement high, take upper limit of mold temperature; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
PVC mold temperature set by rigid/soft grading; 30-50℃ baseline with sufficient cooling, both surface and cycle considered; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
