Flowing Water Pelletizing for PET Bottle Flakes
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.

Underwater 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
Four models span 70–1000 kg/h: the AMFP100 (2.2 kW, 6 strands, 70–100 kg/h), AMFP300 (4 kW, 15 strands, 100–300 kg/h), AMFP500 (7.5 kW, 25 strands, 300–500 kg/h), and AMFP1000 (15 kW, 42 strands, 500–1000 kg/h).
The system is developed for PET flakes that are not fully clean. Water flow pulls the strands into the pelletizer, which avoids strand breakage during screen changes and reduces material loss, producing uniform pellets from PET beverage bottle flakes for reuse in production.
The water-cooling strand line handles most polymers, including color masterbatches, engineering plastics, and filler compounds, and especially modified plastics that need high temperature resistance. Models run from the AMWP50 (1.5 kW, 10–50 kg/h) up to the AMWP1000 (15 kW, 500–1000 kg/h).
Underwater pelletizers range from the AMUP30 at 50–300 kg/h to the AMUP200 at 2–6 t/h, with the AMUP50 at 200–700 kg/h and the AMUP100 at 2 t/h in between. Die hole count rises from 8–10 on the AMUP30 to 100–160 on the AMUP200.
Cutting molten material directly in water maintains pellet shape and prevents oxidation, which matters for sensitive or high-performance polymers. The underwater system suits thermoplastics that need precise pellet size and appearance, especially in high-throughput production environments.
Amstar stocks a full range of spare parts for the flowing water cooling, water-cooling strand, and underwater pelletizing systems. Critical components including blades, filters, die heads, seals, and wear parts are kept in stock for prompt shipment, covering routine maintenance and emergency replacements.
