High mold temperature requirement of PAR
Fenómeno do problema
The mold temperature needs 120-160°C, which conventional water temperature machines cannot meet.
Análise das causas
PAR needs a high mold temperature (close to half of Tg, about 190°C) to reduce internal stress and ensure crystallization.
Solução
Use an oil temperature machine or electrically heated mold; the mold heating system design needs to consider high temperature.
Conclusão principal
PAR has special requirements for the mold heating system.
