PVDF Product Cooling Management
Problem Phenomenon
Deformation from uneven cooling.
Cause Analysis
PVDF crystallization shrinkage is sensitive to cooling; uniform cooling is the key.; 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
①Balance the water channels; ②uniform mold temperature; ③detect temperature differences; ④optimize the design.; After adjustment, take consecutive samples 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
Cooling uniformity is the core of PVDF deformation prevention.; 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
