PET Strap Production Line Featuring Dual Precision Control from Raw Material Drying to Melt Processing for and Consistent Output
PET Strap Production Line Featuring Dual Precision Control
Product Overview
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.
Key Features
- Core Challenge Response: Deep dehumidification drying system addresses PET's hydrolysis tendency with high-precision, multi-zone independent temperature control
- Drying System: Honeycomb rotor dehumidifying dryer with stable dew point ≤ -40°C and adjustable drying temperature
- Extrusion System: PET-specific barrier screw for optimized mixing and shear; cast aluminum heaters with PID intelligent temperature control
- Melt Handling: Optional melt pump stabilizes extrusion pressure and flow, eliminates screw pulsation, and improves thickness uniformity
- Quality Control: Dual precision control from raw material drying to melt temperature processing
