Uneven heating of PP '2079851475616104458 sheet
Problem Phenomenon
After '2079851475616104458, the wall thickness distribution of the product is abnormal, with local excessive thinness.
Cause Analysis
Uneven sheet heating makes the softening degree of each area different; the soft area becomes excessively thin during stretching.; during on-site investigation, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Solution
①Optimize the zoned temperature control of the heating plate; ②check the aging of heating elements; ③adjust the heating curve according to the product; ④ensure sufficient preheating time.; after adjustment, continuously sample and verify the effect, and resume mass production after confirming stability
Key Takeaway
The wall thickness distribution of '2079851475616104458 starts from the heating uniformity of the sheet; zoned temperature control is a fine adjustment means.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
