Underwater Pelletizing Systems

Underwater pelletizing systems are the foundation of modern plastics processing, providing efficient and versatile solutions to turn molten polymers into uniform pellets. With the latest technology, they can handle any polymer and any application. If you want precision, quality, and environmental sustainability, then underwater pelletizing systems are the answer.

Why Underwater Pelletizing Systems?

· Uniform pellets with minimal dust and fines, higher bulk density, and better flow properties.

· Underwater pelletizers can handle a wide range of polymers, including thermoplastics, engineering plastics, masterbatches, recycled materials, and hot-melt adhesives.

· Designed for scalability, they can handle high throughput, making them ideal for large-scale and continuous production.

· Advanced automation for consistent product quality and operational efficiency. Automatic blade pressure adjustment and die cleaning reduce downtime.

· A closed-loop process minimizes water loss, promotes sustainable operations, and maintains a clean working environment.

· Specialized die plates and knife systems for specific applications for even better performance.

Components of Underwater Pelletizing Systems

A typical underwater pelletizing system is an integrated solution consisting of several specialized components to ensure efficient operation and optimal output.

• Pelletizer

Extrudes molten material through a die plate into a submerged cutting chamber.

• Customized Die Plates

Ensures precision shaping of polymers before cutting.

• Process Water System

Keeps the water temperature constant for cooling and transports pellets to the dryer.

• Agglomerate Catchers

Removes plastic clumps to ensure final pellet uniformity.

• Centrifugal Dryers

Separates water from pellets, ready for downstream processing.

• Water Treatment Units

Filters and recirculates water for sustainable operation.

Why Underwater Pelletizing is the Best

Investing in underwater pelletizing systems has many operational benefits over strand or water-ring pelletizers.

·  Better Pellets

Round pellets reduce dust, improve flow, and facilitate downstream processing.

·  Scalability

Handles high volume, perfect for small and large production lines.

·  Less Maintenance and Downtime

The automated and easy-to-clean design keeps operations running smoothly.

·  Sustainability

Closed-loop water systems minimize environmental impact and energy consumption.
