Under Water Die-face-cut Pelletizing Machine

The Under Water Die-face-cut Pelletizing Machine is a highly advanced and innovative system designed for the efficient production of pellets from high-viscosity, elastic, and temperature-sensitive materials. This machine is particularly well-suited for applications involving TPU (Thermoplastic Polyurethane) compounding, EVA (Ethylene Vinyl Acetate) glue granules, and low-temperature, easy-foaming materials such as those used in EVA shoe sole production. 

There are two types of underwaater die-facde-cut pelletizing machine: 

single screw extruder style 

parrallel twin screw extruder style

Below is a detailed overview of the machine, its features, and its applications:

Key Features of the Under Water Granulation Extrusion Machine

• Ensures high efficiency, reliability, and consistency in pellet production.

2. High-Viscosity Material Handling:

• Specifically designed for materials like TPU, EVA, and other elastic compounds.

• Capable of processing materials with poor flow properties and high elasticity.

3. Low-Temperature Processing:

• Ideal for temperature-sensitive materials that are prone to foaming or degradation at high temperatures.

• Maintains optimal processing conditions to preserve material properties.

4. Underwater Cutting Technology:

• The die-face-cut system operates underwater, ensuring smooth and precise cutting of pellets.

• Water acts as a cooling medium, preventing material sticking and ensuring uniform pellet shape.

5. Customizable Pellet Size:

• The pellet size can be adjusted to meet specific requirements, ranging from fine granules to larger pellets.

6. Energy Efficiency:

• Advanced cooling and cutting systems minimize energy consumption while maximizing output.

Applications of the Water Granulation Extrusion Equipment

• Produces high-quality TPU pellets for use in automotive parts, footwear, and industrial applications.

• Ensures consistent pellet size and shape for optimal processing in downstream applications.

2. EVA Glue Granule Production:

• Ideal for creating EVA glue granules used in adhesives, coatings, and sealants.

• Maintains the material's adhesive properties and prevents degradation.

3. EVA Shoe Sole Pellet Production:

• Produces EVA pellets for manufacturing lightweight, flexible, and durable shoe soles.

• Handles low-temperature foaming materials without compromising quality.

4. Other Elastic and Foaming Materials:

• Suitable for processing a wide range of elastic and foaming materials used in various industries.

Under Water Granulation Extrusion Machine Components and Process

1. Extruder:

• The raw material is fed into the extruder, where it is melted and homogenized.

• The extruder screw pushes the molten material through the die plate.

2. Die Plate:

• The die plate shapes the molten material into strands or a continuous sheet.

• The design of the die plate determines the shape and size of the pellets.

3. Underwater Cutting System:

• The strands or sheet are cut into pellets by rotating blades submerged in water.

• The water cools the pellets instantly, preventing deformation and sticking.

4. Water Circulation and Cooling System:

• A closed-loop water system ensures efficient cooling and recycling of water.

• The water temperature is controlled to optimize pellet quality.

5. Pellet Drying and Collection:

• The pellets are separated from the water and dried using a centrifugal dryer or similar system.

• The dried pellets are collected for packaging or further processing.
