PET Bottle Flake Pelletizing Line (High Viscosity)
Our PET pelletizing system transforms clean PET flakes into high-value pellets for injection molding, sheet production, and other downstream applications where stable quality matters.
- Built around moisture removal, stable extrusion, degassing, filtration, and underwater pelletizing.
- Designed to maintain PET material quality and support higher-value reuse.
- Available in practical output ranges from 300 kg/h to 1200 kg/h depending on model.
Equipment Overview
Main Pelletizing System
The system is arranged for compact moisture removal, stable single-screw extrusion, filtration, and underwater pelletizing to convert PET flakes into reusable pellets.
Advanced Technology for Superior Pellets
Advanced Moisture Removal
A compactor removes moisture, helping maintain the intrinsic viscosity of PET material.
Efficient Single Screw Extrusion
A high-quality nitride steel screw supports compacting, melting, and homogenization of PET flakes.
High-Purity Vacuum Degassing
Removes low molecular weight materials and residual moisture to improve final pellet purity.
Uniform Underwater Pelletizing
Transforms melted PET into high-quality, uniform granules with stable shape and consistency.
Working Principle
Our PET pelletizing line follows a precise multi-stage process to convert PET flakes into high-grade pellets.
1. Feeding and Moisture Removal
An automated system controls feeding speed, while a compactor removes moisture from the flakes.
2. Single Screw Extrusion
The PET material undergoes compacting, melting, and homogenization in the high-performance extruder.
3. Barrel Processing
The nitride steel barrel heats the plastic with precise temperature control for consistent melting.
4. Vacuum Degassing
This step removes low molecular weight materials and residual moisture from the melted PET.
5. Melt Filtration
A dedicated filtration stage improves the purity of the melted plastic before pelletizing.
6. Pelletizing
The underwater pelletizing system transforms the melted PET flakes into uniform, high-quality granules.
7. Drying and Bagging
Pellets are dried via a vibration sieve and centrifugal dryer, then bagged for distribution.
Sustainable Plastic Production
The PET plastic flake single screw pelletizer provides an efficient route from recycled flakes to uniform pellets, helping plants increase PET reuse and improve final application value.

Frequently Asked Questions
Pelletizing transforms PET flakes into uniform, dense pellets. This expands their utility beyond flakes and makes them suitable for applications such as injection molding and sheet production.
Moisture can degrade PET during melting and reduce intrinsic viscosity. Moisture removal and degassing help maintain higher IV and more stable pellet quality.
Yes. The system can be equipped with different melt filtration technologies depending on contamination level and the required purity of the final pellets.
