Thermal Management

Thermal management of the tooling and dies is a critical production factor in quality die casting.

If die faces overheat during a casting run, "heat checking" can occur.

Heat checking is the formation very fine surface cracks on the die faces, which will transfer to the die casting as raised veins on the surface..

The die casting engineer has to consider the thermal loads that occur in production (in terms of the thermal mass and the cycle rate) and ensure that the die faces do not overheat.

Heat Checking
on a Die Face

Decardy Die Casting uses active thermal control to manage die face temperature during the production run. The die blocks have cooling channels in which temperature-controlled oil circulates to keep die faces at the desired temperature. This ensures complete fill and rapid solidification while preventing heat checking and die cracking.
