The Full AM Spectrum.
In-House. In Control.

HTS Additive Manufacturing Technologies

We use four in-house additive manufacturing technologies – each suited to a different kind of challenge, performance demand, and precision level. From ultra-detailed lattice structures to thick-walled giants, we apply the right method to match geometry, material, and function. 

Not every challenge needs the same tool. That’s why we have the full toolbox:

Four in-house AM technologies

As the only global producer with four in-house additive manufacturing technologies, we provide top-of-the-line iTherm® conformally cooled components, that meet even the most stringent application requirements.

MFT Explained

HTS proprietary Metal Fusion Technology
  • MFT is a HTS proprietary additive manufacturing technology based on liquid diffusion. 
  • It enables the machining of flow channels before the bonding, allowing for smooth polished channel surface and complex geometries.
  • The MFT bonding process is highly robust and thoroughly validated for hot runner applications. The bond strength matches the tensile strength of the base material, which in this case is forged tool steel.

01

Channels Machining

Plates of Base Material

  • Channels are milled into the base material.
  • Channel surface can be polished or coated.

02

Bonding

MFT Bonding

  • Base material plates are bonded into one block.
  • The tensile strength of the bond equals the one of the base material.

03

Final Shape Machining

Finished Manifold Plate

The final fixtures, grooves and 3D shapes are milled according to the specified tolerances.

Optimized configuration for uniform polymer flow and minimized resin retention.

Channels with smooth transitions

The resin distribution channels can be precisely and specifically tailored to the exact requirements of the process, with complete design freedom, not constrained by the limitations of conventional drilling methods.

iTherm® channel

Bond tensile strenght equal to base material

The bond strength created utilising MFT equals the tensile strength of the base material used. Each bonding surface is meticulously tested with an ultrasonic inspection to ensure perfect diffusion.
