1. Product Introduction
This production line is designed specifically to conquer the sensitive processing characteristics of PET material. PET is prone to hydrolysis, and its melt viscosity is extremely sensitive to temperature. Therefore, we have integrated a deep dehumidification drying system and a high-precision extrusion temperature control module. By ensuring ultra-low raw material moisture content (≤50ppm) and uniform, stable melt temperature (±1°C), the line provides the perfect processing environment for PET. This is not only the foundation of production but also the core prerequisite for obtaining excellent product mechanical properties, high clarity, and stable output rates, allowing you to truly "master" rather than "compromise with" PET's processing window.
2. Main Specifications
Core Challenge Response: Configures a deep dehumidification drying system to address PET's hydrolysis tendency; achieves high-precision, multi-zone independent temperature control for its narrow processing window.
Drying System: Utilizes a honeycomb rotor dehumidifying dryer with stable dew point ≤ -40°C and adjustable drying temperature to ensure raw material moisture meetingthe standard.
Extrusion System: Equipped with a PET-specific barrier screw for optimized mixing and shear; cast aluminum heaters with PID intelligent temperature control, each zone independently closed-loop.
Melt Handling: Melt pump optionally available to further stabilize extrusion pressure and flow, eliminate screw pulsation, and improve thickness uniformity.
Quality Control: Implements dual precision control from the source (raw material drying) to the process (melt temperature), laying the cornerstone for product quality.

4. FQA:
Q1: Why is drying so emphasized for PET production? What are the consequences of excessive moisture?
A1: 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?
A2: 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.
