Application Scenarios of PET-Specific Mold Dehumidifier
The dehumidifier supplies -10℃ dew point dry air to mold surfaces, blocking moisture from cold PET molds and eliminating condensation defects—critical for PET production.
1. PET Bottle Preform Injection
For beverage/food PET preforms (especially hot runner molds).
Molds cool rapidly via ice water (surface temp shorten cycles, causing condensation. Its -10℃ dew point air keeps cavities dry, avoiding bubbles/cold spots and maintaining preform transparency.
2. High-Humidity PET Workshops
Used in rainy seasons, coastal areas (humidity >60%), or open spaces.
Even with dried raw materials, workshop moisture condenses on molds. Its -10℃ dew point air creates a dry barrier, preventing preform appearance issues 24/7.
3. High-Requirement PET Products
For food-grade PET packaging, transparent containers, and precision parts.
Condensation ruins appearance and causes mold rust. Its -10℃ dew point air stops condensation and protects molds.
4. Mass Continuous PET Production
In large-scale manufacturing, continuous mold cooling leads to persistent condensation (regular air-blowing fails).
Its stable -10℃ dew point air supports 24/7 production, boosting efficiency by 20% and cutting rejection rates by 15%.
