TPE Overmolding Temperature Matching
Sorun Belirtisi
The hard plastic substrate deforms during TPE overmolding, or insufficient TPE temperature causes poor bonding
Neden Analizi
TPE overmolding temperature must match the hard plastic substrate: PC substrate TPE temperature 200-220℃, ABS substrate 180-200℃, PP substrate 160-180℃; insufficient temperature gives poor bonding, excessive temperature deforms the hard plastic
Çözüm
①Set the TPE temperature according to the hard plastic substrate; ②Preheat the hard plastic to improve bonding; ③Verify temperature matching by mold trial; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
TPE overmolding temperature is a function of the substrate; PC, ABS, and PP each have corresponding windows, and mold trial verification is a necessary step; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
