Uneven Mold Temperature Distribution in PBT '2079851475616104452
Fenómeno do problema
The temperature difference between mold regions is too large (>10°C), and the crystallinity and shrinkage of various parts are inconsistent.
Análise das causas
The cooling water channel design is unreasonable, with under-cooled and over-cooled areas; the water channels are blocked or scale affects heat transfer.
Solução
Optimize the cooling water channel design to ensure uniform cooling; regularly clean the water channels; use multi-point monitoring of the mold temperature.
Conclusão principal
The uniformity of PBT mold temperature is the basis of product consistency.
