PVDF Product Venting Design
Problem Phenomenon
Trapped gas problem.
Cause Analysis
Poor venting; PVDF decomposition gas also needs to be vented.; 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
①Improve venting; ②focus on the end; ③regular cleaning; ④speed reduction as an aid.; 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
Venting design is a key point of PVDF molds.; 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
