Influence of Die Temperature Control on Solidification and ...

Permanent mold metal casting processes use tempering with oil, water or air as state-of-the-art method for temperature control of certain regions. This approach aims at either creating certain temperature gradients inside the die thus leading to better casting quality or cools down critical hotspots in order to decrease cycle times or increase service life.

The Metal Casting Operation

How To Increase Fluidity In Metal Casting: -Increase the superheat: If a melt is at a higher temperature relative to its freezing point, it will remain in the liquid state longer throughout the metal casting operation, and hence its fluidity will increase. However, there are disadvantages to manufacturing a metal casting with an increased superheat.
