Mold Corrosion Caused by Poor Cooling Water Quality During PBT '2079851475616104452
Problem Phenomenon
The mold cooling water channels are rusted or corroded, and the cooling efficiency decreases.
Cause Analysis
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.
Solution
Use treated cooling water (neutral pH, deionized); use stainless steel water channels or anti-rust coatings; flush regularly.
Key Takeaway
PBT mold cooling water management extends mold life.
