60hp Water-cooled Screw Type Chiller With Hanbell Compressor Use For Cooling 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. During the production process, the chilled 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 chiller used in the injection molding machine.

The role of chillers for injection molding machines:
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
