iTherm® Water Distribution Plate

iTherm® Water distribution plate 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 cooling water (IN and OUT) and standard connectors to Gate Inserts.

Connecting channels can be freely designed according to the cooling/heating requirements of the tool, not by the limitations of using the conventional drilling method.

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 water distribution plate

More freedom designing connecting channels

In comparison with conventionally made water distribution plate, using iTherm® Water distribution plate, you have extra flexibility to bring cooling channels near that critical zones.

Simpler tool assembly

When connecting single gate inserts to the cooling circuit, you need 2 connectors for each Insert. With iTherm® Water distribution plate, you need 2 connectors for a complete system. This reduces the tool complexity and makes the assembly faster.

No leakages

When connecting Single Gate Inserts to the cooling circuit you need 2 connectors for each Insert. With iTherm®Water distribution plate, you need 2 connectors for a complete system. Such assembly eliminates leakages and leakage related production downtimes.


Cooling power

Cooling power range is between 5.0 and 30.0 W/cm2 of heat extraction.

Dimensional range

Length 150 - 800 mm  (5.91 - 31.5 inch)
