Hot Runner Manifold

Best-in-market, quickly configurable, ready-to-use solution with balanced flow paths, consistent pressure drop and uniform shear stress .

Key features and benefits

Conformal design – Enables round and gradual flow path transitions and eliminates the need for plugging.

Forged tool steel – Extensive range of EU-manufactured materials equivalent to your specified steel grades.

Polished channels – MFT technology enables channel polishing and coating before bonding, ensuring smoothness below 0,5 Ra.

More uniform resin distribution – Equal flow paths across all cavities ensure consistent resin flow, resulting in uniform part quality.

Quicker color/material change – Optimized flow paths and reduced residence times lead to faster heat-up, cooling, and overall cycle times.

Cycle time reduction – Optimal resin temperature, minimizing residence time, and lowering the pressure requirements, resulting in faster injection speeds.

iTherm® HR Manifold production process

MFT Technology

MFT is a HTS proprietary additive manufacturing technology based on liquid diffusion, used to produce iTherm® hot runner manifold plates.

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.

iTherm® HR Manifold advantages

Optimized configuration for uniform polymer flow and minimized resin retention.

Conformal design allows for the implementation of smooth channels that enable optimal resin flow. Unlike traditional flow channels, which are usually straight and drilled into the manifold plate, conformal design channels are custom-shaped to optimize performance and efficiency. This tailored approach enhances material flow since channels are designed to accommodate the characteristics of the resin and molded part requirements.

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.

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.

Cycle time reduction

iTherm® Manifold Plates ensure optimal resin temperature, minimizing residence time, and lowering the pressure requirements, resulting in faster injection speeds.

Improved part filling

Compared to conventional manifold plates, iTherm® Manifold Plates enable the design of equal-length channels, shorter flow paths, and consistent pressure drop, ensuring more uniform resin distribution and improved part filling, eaching ∆ < 0,5, even when dealing with non-symmetrical drop configuration.

Quicker color/ material change

Resin distribution channels inside iTherm® HR Manifold plate have no plugs, no dead zones and no sharp corners, resulting in quicker color change and less color-change related scrap.
