42% temperature drop using iTherm® Core
Our customer that produces castings for the automotive industry was trying to increase the cooling rate of the core. The temperature during casting was peaking at 645°C and averaging at 420°C.
They decided to replace the conventional core with iTherm® conformally cooled core to bring cooling channels closer to the critical part of the core.

iTherm® Core
Once in production, iTherm® Core proved to have a substantially faster cooling rate than the conventional core.

Temperature difference
at body hottest spots
ΔT=277 °C – 1 84°C = 93°C
ΔT=530 °F – 363°F = 167°F
at tip (critical zone, engineered cooling):
ΔT=277 °C – 132 °C = 145 °C
ΔT=530 °F – 270°F = 260°F

Temperature difference
at body hottest spots
ΔT=163 °C – 123°C = 40°C
ΔT=326 °F – 253°F = 73°F
at tip (critical zone)
ΔT=163 °C – 79°C = 84°C
ΔT=326 °F – 174°F = 152°
Improvements
with iTherm® Core
Substantially lower core temperatures
Thermal management of conformally cooled iTherm® Core resulted in a 42% lower peak temperature, from 645°C to 378°C. The average temperature has dropped significantly as well, from 420°C to 258°C (-31%)
