Mold Corrosion Caused by Poor Cooling Water Quality During PBT '2079851475616104452
Fenómeno del problema
The mold cooling water channels are rusted or corroded, and the cooling efficiency decreases.
Análisis de la causa
The cooling water quality is poor (improper pH value, containing corrosive ions); the mold material is not corrosion-resistant; it is used for a long time without maintenance.
Solución
Use treated cooling water (neutral pH, deionized); use stainless steel water channels or anti-rust coatings; flush regularly.
Conclusión clave
PBT mold cooling water management extends mold life.
