100hp Water-cooled Screw Type Low Temperature Chiller With Double Hanbell Compressors For Injection Molding Machine
100hp Water-cooled Screw Type Low Temperature Chiller With Double Hanbell Compressors For Injection Molding Machine
After the plastic pellets are heated and melted in the injection molding machine, they are taken into the mold and condensed. The mold is opened and ejected to form the plastic workpiece. In the continuous production process, the cooling water system of the industrial chiller is required to cool the mold to reduce the plastic condensation time and improve the workpiece size accuracy, molding quality and oral quality. This is the working principle of the injection molding machine chiller.

Why do water chillers need cooling towers?
- Generally, water-cooled chillers need cooling towers, because cooling towers are a supporting equipment for water-cooled chillers. Without the cooling water source of the cooling tower, the water-cooled chiller cannot operate.
- Because the running chiller itself will generate a lot of heat, if the air cooling method is used, the overall cooling is poor and is affected by the ventilation environment.
- Using an air-cooled industrial chiller in an environment with poor ventilation conditions cannot be compared with a water-cooled industrial chiller in terms of cooling performance and low temperature environment.
How to select the model of the chiller ?
-
In the production process, the injection molding machine needs to cool the mold to achieve rapid condensation of plastic, improve product quality, and improve production efficiency.
-
Here, the chiller is indispensable. Chiller used in injection molding machine, through extrusion, blow bottle, thermoplastic, hydraulic system four steps to achieve rapid condensation of plastic.
-
This shows the importance of the chiller to the injection molding machine. In the selection of chiller should pay attention to:
-
In mold cooling, the choice of ice water energy depends on its specific heat capacity with the molding material, the temperature at the time of sol, the weight, and the temperature at the time of product release.
-
In terms of temperature difference, the smaller the temperature difference, the more ice water flow is required to carry away the same heat, and the smaller the ice water flow is require
