1. Prevent Sticking
• High-temperature Materials
Hot melt glue is in a high-temperature molten state when extruded and is prone to sticking. If cooled in the air, the particles may stick to each other, affecting product quality and subsequent processing.

• Water Cooling
Underwater granulating method cools the extruded hot melt glue with water, which can quickly reduce the remperature, prevent the particles from sticking, and ensure that the particles are independently dispersed.
2. Control Shape and Size
• Uniform Cuttinig
The underwater granulator can provide uniform cutting effects, ensuring that each particle is of uniform size and regular shape. This is very important for ensuring the uniformity and processability of the product.

• Precise Control
By adjusting the parameters of underwater granulator, the size of the partivles can be precisely controlled to meet the needs of different applications.

3. Improve Production Efficiency
• Continuous Production
Underwater granulator can achieve continuous production, improve production efficiency, and reduce intermediate links and downtime.

• Efficient Cooling
Water cooling method is not only fast and uniform, but also more efficient than air cooling, which can significantly shorten the cooling time and improve production efficiency.
4. Improve the Working Environment
• Reduce Dust
During underwater granulation, hot melt glue is cooled and cut directly in the water, which reduces dust and smoke that may be generated during the production process and improves the working environment.

• Reduce Noise
Compared with air granulation, the noise during underwater granulation is lower, which is beneficial to the health and comfort of operators.

5. Improve Product Quality
• Stable Performance
Underwater granulation can ensure that hot melt glue is heated evenly during the cooling process, avoid the formation of internal stress, and improve the physical properties and stability of the product.

• Appearance Quality
Through underwater cooling and granulating, the surface of the particles is smooth and free of bubbles and impurities, improving the appearance quality of the product.
