Gate clogging of PET injection mold
Fenómeno do problema
The gate frequently clogs during PET '2079851475616104452, injection pressure rises abnormally, and production is interrupted.
Análise das causas
PET cools, crystallizes and solidifies too fast at the gate; gate size is too small; mold temperature in the gate area is on the low side.
Solução
Increase gate size; increase mold temperature in the gate area to 140-160°C; use a hot runner system.
Conclusão principal
The fast crystallization characteristic of PET easily causes gate clogging and needs to be addressed through mold temperature and gate design.
