smartFLOW Helix explained simply
smartFLOW Helix is an advanced version of the tried and trusted manifold technology smartFLOW, specially optimised for use in valve gate hot runner systems. At the heart of this solution is a unique flow geometry that creates a targeted vortex (‘helix’) in the nozzle. This ensures that the melt flow is effectively homogenised before it enters the cavity.
Technical added value in detail
Uniform melting thanks to improved flow control
The innovative flow geometry ensures that the melt is thoroughly mixed in the nozzle area before entering the cavity. This reduces local temperature and pressure fluctuations in the melt flow and ensures uniform filling – particularly advantageous for complex or thin-walled items.
Reduced pin problems and optimal pin position
A common challenge with valve gate systems is what is known as pin shadow. The special flow control of smartFLOW Helix reduces this effect and also minimises the formation of injection errors.
Rheological flow channels for reduced shear stress
In addition to the special incoming flow technology, the diffusion-welded hot runner manifolds ensure uniform melt flow thanks to their rheological design, which is optimally aligned with the flow properties of the plastics. Diffusion welding allows the channels to be integrated precisely and with high surface quality, thereby avoiding pressure losses and hot spots.
Our recommendation
We particularly recommend this technology for technical plastics, frequent colour changes or high optical requirements. It ensures uniform melt flow, consistent part quality and stable processes – even in standard applications, it offers advantages through reduced scrap and uniform filling.
