An underwater pelletizing system refers to a method of pelletizing where molten polymer is directly cut into pellets at the die face while submerged in water. The pellets are rapidly cooled and solidified, leading to a highly uniform shape and size of the pellets.

Maxwell, a reputable underwater pelletizing system manufacturer in India, creates and provides precise pelletizing systems to satisfy the expanding needs of the PET recycling, polymer compounding, and plastic manufacturing sectors.

What Is an Underwater Pelletizing System?

An underwater pelletizing system is a pelletizing method in which molten polymer is cut into pellets directly at the die face under water. The pellets are rapidly cooled and solidified, leading to a highly uniform shape and size of the pellets.

In contrast to conventional strand pelletizing, this system removes the issues of strand breakage and the need for manual handling, rendering it suitable for continuous and high-capacity production lines.

Systems for underwater pelletizing are frequently utilized for:

How Does an Underwater Pelletizing System Work?

The underwater pelletizing process consists of a meticulously regulated sequence:

  1. Molten polymer is expelled from the extruder via a pelletizing die plate.
  2. A rotating cutter equipped with hardened pelletizing blades slices the polymer strands beneath the water’s surface.
  3. Water rapidly cools and solidifies the pellets.
  4. The pellets, along with the process water, are transported to a centrifugal dryer.
  5. Dry and uniform pellets are then released for packaging or additional processing.

At Maxwell, every component is designed to guarantee consistent cutting performance, extended service life, and minimal downtime.

Key Components of an Underwater Pelletizing System

  • Pelletizing Die Plate
    Die plates are produced using high-quality alloy or stainless steel to endure elevated temperatures and pressures.
  • Pelletizing Blades
    Blades with high wear resistance deliver a clean cutting action and minimize the generation of fines, even under continuous operation.
  • Water Chamber
    The water chamber upholds regulated cooling conditions and facilitates stable pellet formation.
  • Pellet Dryer
    Effective separation of water from pellets ensures a dry output and maintains consistent pellet quality.

Advantages of Underwater Pelletizing Systems

Selecting an underwater pelletizing system provides numerous operational and quality advantages:

  • Consistent pellet size and shape
  • Appropriate for high-output extrusion lines
  • Minimal generation of dust and fines
  • Completely automated operation
  • Outstanding cooling efficiency
