The role of cooling system for Plastic granulator pelletizing machine line

What is the function of the plastic granulator machine cooling system? After the extruded strip leaves the machine head, the waste foam should be cooled and shaped immediately, otherwise it will be deformed under the action of gravity. The cooling method is usually cooled by water and divided into quenching and slow cooling depending on the water temperature. Quenching is the direct cooling of cold water. Quenching is beneficial to the shaping of plastic extrusion coating. However, for crystalline polymer, due to the rapid cooling, it is easy to residual internal stress in the extrusion layer, resulting in cracks during use. The layer is quenched. Slow cooling is to reduce the internal stress of the product, and water in different temperatures is placed in the cooling water tank to gradually cool down the product.

The above is the role of the plastic granulator cooling system, I hope to help you.
