PP Welding and Joining
Problembeschreibung
【Problem Phenomenon】PP parts need welding assembly, process selection evaluation
Ursachenanalyse
PP can be hot plate welded, vibration welded, ultrasonic welded, and heat staked; welding of crystalline materials requires controlling temperature and pressure; solvent bonding is difficult; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Lösung
Select hot plate or vibration welding according to structure; optimize ultrasonic welding parameters; avoid solvent bonding; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Wichtigste Erkenntnis
PP welding selects hot plate and vibration welding, solvent bonding is difficult; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
