PVDF Product Rough Surface
Problem Phenomenon
The surface is not smooth.
Cause Analysis
Low mold temperature causes poor replication or insufficient melt temperature; the mold surface condition also has an effect.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Increase mold temperature and melt temperature; ②polish the cavity; ③clean the mold surface; ④stabilize the process.; After adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Surface quality is managed by temperature and mold surface.; 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
