Problem Phenomenon
The product sticks to the mold.
Cause Analysis
PVDF melt tackiness interacts with the mold surface; improper mold temperature or demolding design.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience; This mechanism has been repeatedly verified by industry materials, and it should be confirmed first during troubleshooting
Solution
①Optimize mold temperature; ②increase the draft angle; ③proper mold surface treatment; ④standardize mold release agent.; After adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Mold sticking is solved from temperature and structure.; After confirming effectiveness, fix 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
