iTherm® PISTON/PLUNGER
iTherm® Piston/plunger is a single HPDC component with specially designed internal cooling system. Using it results in substantially extended piston lifetime (up to 3x) and less porosity in the cast product.
General Information
iTherm® Piston/plunger is produced using tool steel forged or rolled bars and HTS proprietary additive manufacturing technology.
It is a single body component with equal mechanical properties as tool steel monoblock.
Cooling channels can be freely designed according to the cooling/heating requirements of the product, not by the limitations of using the conventional drilling method.
There are different iTherm® Piston models for different machine sizes and applications.
It is highly customizable to specific customer requirements.
Advantages
over conventional piston
More freedom designing cooling channels
In comparison with the conventionally made pistons, iTherm® gives you extra flexibility to bring cooling channels near the critical zones of the piston.
More uniform heat distribution on the working surface
In comparison with the conventionally made pistons, using iTherm® Piston, the heat is distributed much more evenly over the surface, so the piston is cooling down more evenly and faster.

Longest life time on market
With iTherm® Piston, the conformal cooling of the steel allows the heat removal rate to exceed that of BeCu tips while extending its lifetime due to low transient stresses in the membrane.
Our customers have reported more than 120.000 shots lifetime of iTherm® Piston (with 3x ring replacements).

No premature Al solidification
In the pour phase of the cycle, iTherm® Piston temperature is higher compared to other pistons, (low heat capacity of steel membrane) preventing premature aluminium solidification.
Rapid biscuit cooling
Due to high iTherm® Piston cooling effectiveness, extreme temperature drop occurs in the injection/pressurization phase, resulting in rapid biscuit cooling.
Cycle time reduction
Due to the supreme thermal management characteristics of iTherm® Pistons, their usage results in up to 15% shorter cycle time.
