Advanced Underwater Pelletizing System UWP Pelletizer for Polymer Granulation
Product Description
Product Overview
Nanjing Haisi Extrusion Equipment Co., Ltd. proudly presents our cutting-edge UWP system designed for high-end polymer granulation. Engineered for precision, high throughput, and long-term reliability, our state-of-the-art UWP pelletizer ensures that molten polymer is cut directly in a closed-loop water chamber, producing perfectly spherical, uniform, and dust-free granules for a wide range of demanding thermoplastic applications.
Advanced System Configuration
Precision Die Face Cutting Head: Features high-speed rotating blades operating against a specially hardened tungsten carbide die plate, ensuring clean shear cuts and extended component service life.
Optimized Water Circulation Unit: Maintains precise temperature control and water flow dynamics to instantly solidify and quench newly cut pellets without clogging or agglomeration.
Centrifugal Dryer and Dehydrator: Rapidly separates cooling water from the finished granules, delivering thoroughly dried, high-bulk-density plastic particles ready for packaging.
Integrated Automated Control System: Advanced PLC touch-screen control monitors cutter speed, water temperature, melt pressure, and motor load for seamless, safe factory operation.
Technical Advantages
Superior Granule Morphology: The advanced UWP pelletizing process creates smooth, uniform, round pellets that significantly enhance feeding consistency in downstream injection molding and extrusion processes.
Zero Fines and Dust: Cutting underwater completely eliminates airborne polymer dust and irregular edges, ensuring a clean working environment and maximum material recovery.
Wide Material Compatibility: Highly effective for processing soft elastomers, high-viscosity engineering plastics, masterbatches, and sensitive biopolymers that struggle with traditional strand or air-cooled cutting.
Low Maintenance Design: Quick-change blade mechanisms and wear-resistant sealing components minimize operational downtime and reduce maintenance labor costs.
Typical Applications
This advanced water-face granulation system is ideal for processing:
Thermoplastic elastomers (TPE, TPR, TPU, TPV)
Engineering plastics (PA, PC, POM, PBT, ABS)
Color masterbatches and high-loading functional additives
Biodegradable polymers (PLA, PBAT, PHA)
