PC Mold Deposit
Problem Phenomenon
[Problem Phenomenon] Long-term PC production causes mold area buildup and vent blockage
Cause Analysis
Additive precipitation and deposition; high mold temperature accelerates migration; fine vents are easily blocked; when troubleshooting on site, verify each item according to this mechanism one by one, and avoid blindly adjusting the machine based on experience alone; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
Regularly clean the mold and vents; analyze the buildup and adjust the formulation; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes, so as to locate effective measures
Key Takeaway
PC mold deposit requires regular cleaning, with venting as the focus; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
