iTherm® Distributor/ Shot Block

iTherm® Distributor is produced using tool steel forged or rolled blocks 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.

We produce flat or round distributors, depending on the injection system and cast part.

It is highly customizable to specific customer requirements.



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


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.


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 distributor

More freedom designing cooling channels

In comparison with the conventionally made distributor (image on the left), iTherm® Distributor (image on the right) gives you extra flexibility to bring cooling channels near that critical zones of the distributor.

More uniform heat distribution on the working surface

In comparison with the conventionally made distributor, using iTherm® Distributor the heat is distributed much more evenly over the surface, so the distributor is cooling down more evenly and quicker.

Faster biscuit solidification

In comparison with the conventionally made distributor, using iTherm® Distributor you gain time in the phase of biscuit solidification, decreasing the biscuit problems related down time.


Cycle time reduction

Combining the advantages of iTherm® Distributor you can significantly shorten cycle time. Our customers have reported up to 20% shorter cycle times when replacing conventional distributor with iTherm® Distributor.
