UDTECH Underwater Pelletizing System
Material compounding and granulation technology is best evident in UDTECH’s Underwater Pelletizing System. This advanced system consists of a co-rotating screw extruder and a die assembly suitable for materials with high viscosity, low melt-filament flow index (MI), or difficult to shape making it versatile across several industries.
Supported materials in a System
Among a variety of polymers and materials the system has to offer, the following can be particularly noted:
Thermoplastics such as Thermoplastic Polyurethanes (TPU), Thermoplastic elastomers (TPE), thermoplastic vulcanizates (TPV), thermoplastic rubber (TPR), polypropylene (PP), polystyrene (PS), polylactic acid (PLA), Polyvinyl alcohol (PVA), and Styrene-ethylene-butadiene-styrene (SEBS)
Specialty materials includes EVA, rubber, hot-melt adhesives, special resins, micro pellets and others.
With these broad compatibilities across different manufacturers geometrically consistent pellet shapes as well as improved thermal stability can be attained.
Key Components and Technology
The UDTECH Underwater Pelletizing System features accurate design and material adoption embodied in start up valve, die head, pelletizer head, water piping systems with circulators, dehydration and drying, vibrating filtration, and additional automation to facilitate the work flow.
The foremost one is the ‘die surface hot cutting’ technology. This technology cut the stream of molten die neck into droplets right upon exiting the die orifice, wherein the droplets are water quenched to form spherical pellets. The system is expected to work with materials with low melting strength and high viscosity and temperature sensitivity by dispensing the negative effects of each by employing controlled temperature.
Performance and Applications
This nose configuration is designed for efficient heat and mass transfer, hence continuous hence forth operation is realized even in extreme conditions. These attributes grant it the application of reactive extrusion which involve polymer engineering of:
Polymer engineering: PUR, PA, POM, Pei, PC, PMMA, PBT, PPS in different forms.
Chemical modifications: Dynamic vulcanization, crosslinking, grafting and chain extension.
With the above order of matters, the processing stages distribute the narrow retention time, reduce temperature gradients and have excellent surface area of contact leading to higher quality of the material and the final product.
What bothers you about the choice of another underwater pelletizing system?
Performance: Designed for continuous high throughput mode fully automated.
Versatility: Capable of processing virtually all chemicals and compounds in any form.
Durability: Engineered to sustain in extreme environments with very limited time loss during maintenance.
With UDTECH's underwater pelletizing system, whether it relates to the production of conventional polymers or polymerization processes involving complex reactants, the goals of various industries with regards to precision and efficiency in pellet production can be accomplished.

Underwater Pelletizing System Prices
Cost of Underwater Pelletizing Systems: Concerning costs, you can get the right solutions based on your production level and the budget intended, while you still achieve high-quality pellets at reasonable prices.

- Single Screw Extruder Pelletizing Line: These systems are used for relatively uncomplicated purposes, usually are at the lower end of the price-range
- Double Screw Extruder Pelletizing Line: These are rather complicated and flexible and worked on several categories of substances thus are costlier than the single screw counterparts.
- Other Specialized Systems: There are other specialized ones available too for eg on soft or hard polyvinyl chloride polyethylene extrusion and so many others which affect pricing too.
Depending on their design and specifications, the underwater pelletizing systems are priced differently. To illustrate, the cost of a budget underwater pelletizing system can be as low as $50,000 per piece while other systems with more features can be sold at around $60,000 per piece.
