Ideal for PET Bottle Flake Recycling
This pelletizing system is specially developed for processing PET flakes, especially when the input material is not fully clean. It uses a water flushing strand method, where the strands are pulled into the pelletizer by the water flow—avoiding strand breakage during screen changes and reducing material loss.
Key Features:
- Water Flushing Cooling Tank: Quickly cools the strands and helps move them smoothly into the pelletizer, improving overall efficiency.
- Stainless Steel Pelletizer: Handles in-water cutting with strong corrosion resistance, ideal for PET material.
- Effective Moisture Removal: After pelletizing, the system connects directly to a centrifugal dryer to remove surface water and improve drying.
- Frequent Screen Changes: Includes a large-area cartridge screen changer to handle dirty PET flakes.
Applications:
Perfect for recycling PET beverage bottle flakes into uniform pellets for reuse in production.

Under water pelletizing line
High-Quality Pellet Production for Polymers and Thermoplastics
This system is designed to produce consistent, high-quality plastic pellets by cutting molten material directly in water. The underwater cutting process helps maintain pellet shape and prevents oxidation, which is critical for sensitive or high-performance polymers.
Key Features:
- Underwater Cutting: Molten plastic is cut into uniform pellets immediately in water, ensuring smooth shape and stable quality.
- Fully Enclosed Process: No air exposure during cutting, which avoids rapid cooling and material degradation.
- Highly Automated: Equipped with melt pump, filter, start-up valve, die face cutter, water circulation, and drying units for continuous operation.
Typical Applications:
Ideal for a wide range of thermoplastics and polymers requiring precise pellet size and appearance, especially in high-throughput production environments.

Frequently Asked Questions
Which materials can this pelletizing system process?
The system is specially developed for PET flakes, including input material that is not fully clean. Beyond PET, the water-cooling strand lines handle most polymers — color masterbatches, engineering plastics, filler compounds, glass or carbon fiber reinforced plastics (PP, PA, ABS, PBT), polymer blends, cable materials, and specialty masterbatches with flame retardants or functional additives.
What is the water flushing strand method?
In the water flushing strand method, extruded strands are pulled into the pelletizer by the water flow itself. This avoids strand breakage during screen changes and reduces material loss. The water flushing cooling tank quickly cools the strands and moves them smoothly into the pelletizer, improving overall efficiency — especially useful when running dirty PET flakes with frequent screen changes.
Which models are available, and what capacities do they cover?
Three series are offered. The AMFP flowing-water-cooling series covers 70–1000 kg/hr (AMFP100 to AMFP1000, 2.2–15 kW). The AMWP water-cooling strand series covers 10–1000 kg/hr (AMWP50 to AMWP1000, 1.5–15 kW). The AMUP underwater pelletizing series covers 50 kg/hr up to 2–6 tons/hr (AMUP30 to AMUP200). Choose the series and model that match your material and target throughput.
How does underwater pelletizing differ from strand pelletizing?
Underwater pelletizing cuts molten plastic directly in water, producing uniform pellets with smooth shape while preventing oxidation — critical for sensitive or high-performance polymers. The fully enclosed process avoids air exposure during cutting, preventing rapid cooling and degradation. It is highly automated with melt pump, filter, start-up valve, die face cutter, water circulation, and drying units for continuous operation.
How do I choose between single-screw and twin-screw pelletizing?
The right choice depends on your material and application: single-screw machines suit straightforward melt filtration and pelletizing of cleaner streams, while twin-screw configurations offer stronger mixing for compounds, masterbatches, and reinforced plastics. See our guide on single vs twin screw pelletizer to compare, and ask our engineers to match the extruder type to your formulation.
What spare parts and after-sales support are available?
We stock a full range of spare parts for all three systems — blades, filters, die heads, seals, and wear parts — ready for prompt shipment to minimize downtime. Support includes technical troubleshooting by experienced engineers and long-term supply of consumables over the full equipment lifecycle. Whether you need routine maintenance items or emergency replacements, production keeps running smoothly.
