LDPE Mold Temperature 20-60℃
Problembeschreibung
The product surface gloss is poor, or when mold temperature is too high, demolding deformation occurs and the cycle is prolonged.
Ursachenanalyse
LDPE mold temperature affects crystallization and surface: low mold temperature gives poor surface replication; mold temperature 20-60℃ is the normal range, and each 10℃ mold temperature adjustment requires stabilizing 10 cycles before evaluation.
Lösung
①Mold temperature normally 20-60℃; ②Adjustment amplitude in units of 10℃; ③After each adjustment, stabilize for 10 cycles before judging; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Wichtigste Erkenntnis
LDPE mold temperature adjustment requires patience; 10℃ steps plus 10-cycle stabilization is the standard rhythm to avoid misjudgment; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
