PPSU mold temperature
Fenómeno do problema
PPSU products have high internal stress or poor surface quality; mold temperature deviates from the 149~163℃ range.
Análise das causas
PPSU mold temperature 149~163℃ obtains low internal stress high performance products; low temperature means high stress and poor surface; high temperature means long cycle and mold sticking; uniformity affects consistency.
Solução
①Mold temperature 149~163℃ control; ②temperature uniformity management; ③stress and cycle balance; ④measure actual cavity temperature.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusão principal
The 149~163℃ mold temperature of PPSU is the supplier standard; uniformity ensures consistency; balanced optimization is based on verification.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
