PVC Mold Temperature 30-50℃
Problem Phenomenon
Poor product surface gloss and roughness, or after mold temperature too high, cycle extended and deformation
Cause Analysis
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
Solution
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
Key Takeaway
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
