PVDF Product Gate Design
Problem Phenomenon
Defects in the gate area.
Cause Analysis
Gate form and position affect filling; PVDF viscosity is relatively high so the gate must be reasonable.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Optimize form and position; ②suitable size; ③control shear; ④avoid stressed areas.; 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
Gate design affects PVDF filling.; 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
