LDPE Mold Temperature 20-60℃
Problem Phenomenon
The product surface gloss is poor, or when mold temperature is too high, demolding deformation occurs and the cycle is prolonged.
Cause Analysis
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.
Solution
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.
Key Takeaway
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
