Beyou Underwater Pelletizer For Sale

Underwater Pelletizing (UWP) is an efficient pelletizing method that directly cuts molten polymer into pellets within a water medium. In this process, the molten material flows out of the die holes and is immediately cut into uniform pellets by rotating knives submerged in water. The pellets are then carried by water flow to a centrifugal dewatering device for subsequent drying. This system is especially suitable for pelletizing high-viscosity, high-output, and heat-sensitive materials.

Our Underwater Pelletizer Features

Our independently developed underwater pelletizing system integrates efficient cooling, intelligent control, and broad material adaptability. It plays a key role in modern high-performance extrusion processes, particularly suitable for heat-sensitive materials such as TPU, EVA, and biodegradable plastics.

Smart Control with One-Touch Operation
・Equipped with a PLC control system and touchscreen interface, ensuring intuitive operation and stable, efficient performance.

Multiple Knife Adjustment Options
・Supports mechanical, pneumatic, and hydraulic-pneumatic automatic knife adjustment to meet diverse process requirements with greater precision and flexibility.

Precision Cutting for Durable Operation
・Innovative cutter and die design allows precise adjustment of the gap between blade and die. High-temperature, wear-resistant materials are used for both components, with an automatic pressure-compensation system to extend blade life and ensure stable operation.

Wide Material Compatibility
・Capable of processing high-viscosity, high-fill, and low-flowability materials, ideal for high-performance compounding systems with demanding output and stability requirements.

Fully Automated and Continuous Operation
・Key process parameters such as die pressure, cutter speed, water temperature, and water flow are automatically controlled to enable 24/7 stable production with minimal operator intervention.

Application

This production line is suitable for pelletizing a wide range of thermoplastics, elastomers, and functional modified materials. Typical applications include:

1.Engineering Plastics Compounding
・For reinforced, flame-retardant, or toughened materials such as PA6, PA66, PC, and PBT.

2.High-Filler Masterbatch Production
・For highly filled PP/PE systems with calcium carbonate, talc, and other mineral fillers.

3.Thermoplastic Elastomer Processing
・Including TPU, SEBS, and EVA, widely used in footwear, sealing parts, wire & cable sheathing, etc.

4.Biodegradable Plastics Compounding
・For PLA, PBAT, PHA and other eco-friendly materials used in sustainable packaging and film products.

5.Soft Polyolefin Pelletizing
・For low-melting PP, PE and other flexible materials, commonly used in heat-sealable films and soft packaging.

6.Hot Melt Adhesive Base Material Processing
・Reactive extrusion and pelletizing of PA, TPU, EVA, and other materials for use in packaging, automotive, woodworking, and construction adhesives.
