Scaling in PET mold cooling water channels
Problem Phenomenon
The cooling water channels of PET injection or blow molds are scaled and clogged, and cooling efficiency continuously declines.
Cause Analysis
Poor cooling water quality; hard water with high calcium and magnesium ion content causes scaling; no water treatment equipment is used; high cooling water temperature accelerates scaling.
Solution
Use softened water or deionized water; regularly clean water channels chemically or ultrasonically; install water treatment devices; control water temperature ≤15°C.
Key Takeaway
PET mold water channel scaling is a gradual problem; water quality management and regular maintenance are necessary measures.
