25ton Air Cooled Industrial Water Chiller for Injection Molding Machine

25ton Industrial Water Chiller Units For Injection Molding Machine IMM

After the plastic pellets are heated and melted in the injection molding machine and then taken into the mold to condense, the mold is opened and ejected to form the plastic workpiece. In the continuous 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 injection molding machine chiller.

Why choose a chiller to cool the injection molding machine

1. A mold is a heat exchanger. The heat is transferred from the molten plastic to the mold, and then from the mold to the continuously circulating cooling medium - ice water. Only a small part enters the air and the die plate of the injection molding machine.
2. As we all know, a considerable part of the plastic molding cycle is used for cooling, sometimes accounting for more than 80% of the plastic molding cycle. Therefore, it is absolutely necessary to control the cooling time to a minimum.
   
3. For example, the molding cycle of a mold is generally 20 seconds. If the water in the original cooling tower is replaced with ice water produced by the chiller for cooling, it can be shortened to 16 seconds.
4. Although the initial cost of choosing to equip a chiller is higher, it can increase production by 20%, and in long-term production, it can achieve great benefits.
