Can natural gas mold temperature machine be used for cooling?
announcer:

The mold temperature machine can maintain the mold at a stable temperature, so many people will have such doubts. Does the mold temperature machine have the function of cooling? In fact, the mold temperature machine has a great role in the application of cooling control temperature.

 

The cooling method of the mold temperature machine can be divided into direct and indirect. Direct cooling generally exists in the water temperature machine. It achieves the purpose of rapid cooling by injecting a part of cold water and discharging part of the hot water. The speed of direct cooling is fast and the cost is low, but it is only suitable for water temperature machine, and the temperature control will be short. Moreover, this method is also easy to produce scale in the equipment, affecting the subsequent use of the mold temperature machine. Indirect cooling is to exchange heat through the heat exchanger in the equipment, and then reach the purpose of cooling. This method is more accurate for temperature control and less damage to equipment. But its cooling rate is slower than direct cooling, and its cost is also high.
