In the manufacturing of aluminum alloys, uneven or inappropriate mold temperatures will lead to dimensional instability in the die-casting die temperature machine. During the production process, the ejected castings will be deformed, resulting in thermal pressure, mold sticking, Defects such as surface depressions, internal shrinkage holes and thermal bubbles.

Different manufacturers of die-casting mold temperature controllers may have different set temperatures. Generally, it is more appropriate to set the temperature to be about 20 degrees higher than the mold temperature.

The general appropriate temperature is: the approximate surface temperature of the alloy mold is 180-270°C for aluminum alloy

I hope this can help you.
