TPE overmolding thickness
Fenómeno del problema
Uneven thickness of the TPE overmolding layer
Análisis de la causa
Improper overmolding mold gap or injection parameters; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry materials and should be confirmed first during troubleshooting
Solución
Uniform mold gap; injection parameter optimization; thickness inspection; 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, so as to locate effective measures
Conclusión clave
Overmolding thickness is controlled by the mold and parameters; 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 later
