iTherm® CORE FOR ENGINE BLOCK CASTING
iTherm® core for engine block casting is single-body component with specially designed internal conformal cooling system. It is used in engine block casting for faster and more uniform casting solidification.
General Information
iTherm® Core For Engine Block is produced from tool steel forged or rolled blocks using HTS propriatery additive manufacturing technology.
It is a single body component with equal mechanical properties as tool steel monoblock.
It has only two connectors for cooling medium (IN and OUT).
Cooling channels can be freely designed according to cooling/heating requirements of cast part, not by limitations of using conventional drilling method.
It is highly customizable to specific customer requirements.
Customer statement
We are happy with iTherm Core. Cooling power and service life time are main advantages.
We tested HTS IC concept of iTherm core. Cooling power and service life time of iTherm Cores convinced us to use it in serial production.
Advantages
over conventional core
More freedom designing cooling channels
In comparison with convetionally made Core, iTherm® Core gives you extra flexibility to bring cooling channels near that critical zones.
Even heat distribution on working surface
In comparison with convetionally made core, using iTherm® Core temperatures are lower and the heat is distributed much more evenly over core surface.

Faster cooling
Pictures on left side show temperature at core surface (a) at cycle finish and (b) before start of a new cycle. iTherm® Core surface temperature is around 100 °C lower compared to surface temperature of conventional die core (IR pictures at the right side).
Shorter cycle time
Faster and more uniform surface cooling has substantial effect on Cycle Time. Replacing convetional core with iTherm® Core can improve cycle time by up to 20%
Parameters
Cooling power
between 10 and 30 W/cm2 of heat extraction
