TPU Overmolding Injection
Problembeschreibung
TPU overmolded metal parts have insufficient bonding strength
Ursachenanalyse
Improper metal surface state or preheating temperature results in weak interface bonding; when troubleshooting on site, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
Lösung
Metal surface cleaned and roughened; preheating temperature controlled; choose bonding-grade materials; after adjustment, continuously sample 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
Overmolding bonding strength relies on surface and preheating; 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 similar problems in the future
