iTherm® plunger

iTherm® 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 cooling/heating requirements of the product, not by the limitations of using the conventional drilling method.

There are different iTherm® Plunger models for different machine sizes and applications.

It is highly customizable to specific customer requirements.

HTS DIFFERENCE

INNOVATIVE TECHNOLOGY

Based on MFT™ and DED technologies we produce components with conformal cooling / flow design and mechanical properties of a forged tool steel block.

SUPERIOR PERFORMANCE

iTherm® components have a big impact on cooling and material flow, resulting in shorter cycle times, higher cast/moulded part quality and subsequentially also productivity.

SOLUTION ORIENTED

Years of experience and R&D of HTS Group companies, combined with leading OEM customer partnerships gives us knowledge and capacity to help you improve your productivity.

Advantages over conventional plunger

More freedom designing cooling channels

In comparison with a conventionally made plunger, iTherm® plunger gives you extra flexibility to bring cooling channels near the critical zones.

 

More uniform heat distribution on the working surface

In comparison with a conventionally made plunger, using iTherm® Plunger, the heat is distributed much more evenly over the surface, so the plunger is cooling down more evenly and faster.

Longest lifetime on the market

With iTherm® Plunger, 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® Plunger (with 3x ring replacements).

No premature Al solidification

In the pour stage of the cycle, iTherm® Plunger temperature is higher compared to other pistons (low heat capacity of steel membrane) preventing premature Al solidification.

 

Rapid biscuit cooling

Due to high iTherm® Plunger 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® Plungers, their usage results in up to 15% shorter cycle time.

Configure your iTherm® Plunger online

We have developed an online configurator that helps you configure the parameters of iTherm® Plunger ring according to your specific requirements.

iTherm® conformal cooled shot blocks are cooling quicker and more equally across the working surface, shortening biscuit solidification time

LOOKING FOR FASTER BISCUIT SOLIDIFICATION?

Our innovative rod spray lubrication system which lubricates the sleeve across the whole length will prolong the sleeve and plunger lifetime.
