iTherm® core for engine block casting is a single-body component with a specially designed internal conformal cooling system. It is used in engine block casting for faster and more uniform cast part solidification.
iTherm® Core for engine block casting is produced from tool steel forged or rolled blocks using HTS proprietary additive manufacturing technology.
It is a single body component with equal mechanical properties as tool steel monoblock.
It has only two connectors for the cooling medium (IN and OUT).
Cooling channels can be freely designed according to cooling/heating requirements of the cast part, not by limitations of using conventional drilling method.
It is highly customizable to specific customer requirements.
We are happy with iTherm Core. Cooling power and service lifetime are the main advantages.
We tested HTS IC concept of iTherm core. The cooling power and service lifetime of iTherm cores convinced us to use them in serial production.
In comparison with the conventionally made cores, iTherm® Core gives you extra flexibility to bring cooling channels near the critical zones.
In comparison with the conventionally made cores, using iTherm® Core, temperatures are lower and the heat is distributed much more evenly over the core surface.

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