This production line is engineered specifically to overcome the sensitive processing characteristics of PET material. PET is prone to hydrolysis, and its melt viscosity is extremely sensitive to temperature variations. Our integrated deep dehumidification drying system and high-precision extrusion temperature control module ensure ultra-low raw material moisture content (≤50ppm) and uniform, stable melt temperature (±1°C). This creates the ideal processing environment for PET, forming the foundation for excellent product mechanical properties, high clarity, and stable output rates—enabling true mastery of PET's processing window.

Frequently Asked Questions
Q1: Why is drying so emphasized for PET production? What are the consequences of excessive moisture?
PET is a polyester material highly susceptible to hydrolysis reactions in the molten state. Excessive moisture leads to molecular chain scission, causing a significant drop in the product's intrinsic viscosity (IV). This manifests as severely degraded tensile strength and toughness, brittle products, and even the appearance of numerous bubbles during production, making normal stretching and winding impossible. Therefore, deep drying is the first and most critical barrier to successful PET processing.
Q2: What does a temperature control accuracy of ±1°C mean in actual production?
PET's melt viscosity is very sensitive to temperature changes. A fluctuation of ±1°C can cause viscosity variations, affecting extrusion stability, sheet thickness uniformity, and the stability of subsequent stretching processes. Precise temperature control ensures consistent melt flow, which is the key technical guarantee for obtaining products with high dimensional accuracy, reducing scrap rates, and achieving continuous high-speed production.
