PPS product welding assembly
Problem Phenomenon
Assembly bonding problems.
Cause Analysis
PPS can be ultrasonically welded and laser welded; parameters must be specially developed.; 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 data and should be confirmed first during troubleshooting
Solution
①Develop welding parameters; ②design weld line structure; ③conduct strength verification; ④control consistency.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PPS welding process must be specially developed and verified.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
