This advanced line produces high-performance PET (polyethylene terephthalate) pellets reinforced with glass fibers. Designed for recycling PET flakes (e.g., bottles, packaging) and blending them with glass fibers (10–40%), it creates composite pellets with enhanced strength, thermal stability, and rigidity.
Ideal for automotive, electronics, and industrial applications, the pellets replace virgin materials in manufacturing durable components like housings, gears, and structural parts. The system ensures precise fiber dispersion and minimal degradation of PET.
Built for efficiency, the line integrates twin-screw extrusion, fiber dosing, and pelletizing technologies. It supports sustainable production by repurposing waste PET while improving material performance.

Key Features

Twin-Screw Extruder: Corrosion-resistant, co-rotating screws ensure homogeneous mixing of PET flakes and glass fibers.
Precise Fiber Dosing: Gravimetric feeders control glass fiber content (10–40%) for customized mechanical properties.
High-Temperature Processing: Zones up to 300°C melt PET without degrading fibers or polymer chains.
Vacuum Degassing: Removes moisture and volatiles from recycled PET for defect-free pellets.
Strand Pelletizing: Cuts extruded strands into uniform 2–5 mm pellets with low dust generation.
Wear-Resistant Components: Hardened barrels and screws withstand abrasive glass fibers.
Automated Control: PLC system adjusts temperature, screw speed, and feeding ratios in real time.
Energy Efficiency: Heat recovery systems reduce power consumption by 15–20%.

Process Workflow

Material Pre-Treatment:
PET flakes are dried (<0.02% moisture) to prevent hydrolysis.
Glass fibers are pre-cut and stored in controlled humidity.
Feeding & Mixing:
PET flakes and glass fibers are gravimetrically fed into the extruder hopper.
Melting & Compounding:
Twin screws melt, mix, and disperse fibers evenly within the PET matrix.
Vacuum degassing eliminates trapped air and moisture.
