LDPE Mold Temperature 20-60
Problem Phenomenon
LDPE '2079851475616104452 mold temperature set to 70℃; the cycle is prolonged and sticking to the mold occurs.
Cause Analysis
LDPE crystallizes fast; high mold temperature only prolongs the cycle and easily causes mold sticking; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; This mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting.
Solution
LDPE mold temperature 20-60℃; general parts 30-40℃; cooling water channels ensure flow rate; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Key Takeaway
LDPE follows the low mold temperature route, with cooling efficiency prioritized; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; Incorporate this case into the defect archive as a troubleshooting reference for similar future problems.
