In underwater pelletizing system,the produced pellets are carried away as slurry in water for further cooling in transit, to the dewatering, screening, and drying equipment.underwater pelletizing consists of drive valve, die head, pellezing unit, bypass line, water recycling unit and centrifugal dehydrator.It is good for most of polymers,especially for TPU and TPV or similar elastomer, its advantage plays well.

Excellent Pellet Quality: Underwater pelletizing produces high-quality pellets with uniform size and shape, resulting in consistent material properties and performance. This is particularly crucial for applications where product quality is paramount.
Heat-Sensitive Materials: If you are working with heat-sensitive thermoplastics or materials that degrade at high temperatures, underwater pelletizing is an excellent choice. The water bath rapidly cools the pellets, minimizing heat exposure and preserving material properties.
Reduced Dust and Fumes: Underwater pelletizing virtually eliminates dust and fumes during the cutting process. This is especially important for maintaining a clean and safe working environment, as well as for processing hazardous or sensitive materials.
High Throughput: The cooling effect of the water bath allows for faster production rates compared to some other pelletizing methods. If you need to achieve high throughput while maintaining pellet quality, underwater pelletizing is a suitable option.
The most difference making us outstanding than other vendors is our strong processing capability .
Equipped with more than 50 sets of various types of machining equipment,core parts of the twin screw extruder are all manufactured at our own factory which makes the production cost and quality controllable .That's why our machine enjoy a high performance to price ratio
