PET Preform Molding Automatic Drying & Feeding System
PET is highly hygroscopic.
Challenges: Even trace amounts of moisture can trigger a hydrolysis reaction during the high-temperature injection molding process, leading to:
Molecular chain breakage, resulting in reduced preform strength and brittleness.
Silver streaks, bubbles, and haze on the product surface, affecting transparency.
Increased acetaldehyde (AA) content, impacting the taste of beverages.
Production interruptions, higher defect rates, and increased costs.
Conclusion: Therefore, a stable and efficient automatic drying and conveying system is an absolute prerequisite for successfully producing high-quality PET preforms.
Investing in Reliability, Quality, and Efficiency
Exceptional Drying
Stable ultra-low dew point dry air ensures PET raw material moisture content remains far below standard requirements (e.g., <30ppm or even <10ppm), eliminating hydrolysis.
Highest Quality
Produces crystal-clear preforms with high strength and low acetaldehyde content, providing perfect assurance for final filling.
Energy Efficiency
Closed-loop drying system maximizes thermal energy utilization; fully automated conveying significantly reduces labor costs and enables unmanned operation.
Pollution-Free
Fully sealed system prevents raw material exposure to air, avoiding secondary moisture absorption and environmental contamination.
Intelligent Control
PLC + touchscreen HMI allows intuitive parameter setting, process monitoring, and fault diagnosis, with support for remote connectivity (IoT).
Enhanced Productivity
24/7 uninterrupted stable operation reduces downtime and maximizes injection molding machine utilization.
