Precise flow control for homogeneous melt
smartFLOW Helix is based on the tried and trusted smartFLOW manifold technology and has been specifically developed for use in valve gate hot runner systems. At the core of the solution is a special flow geometry that generates a defined vortex – a helical flow – within the nozzle. This geometry homogenises the melt flow immediately before it enters the cavity. Differences in temperature and pressure within the melt are reduced, promoting uniform filling. Particularly in the case of complex geometries or thin-walled items, optimised flow control helps to ensure stable filling of the mould.
Optimisation of valve gate applications
Valve gate systems place high demands on flow control in the gate area. Conventional systems can, for example, lead to so-called ‘pin shadows’ in the injection area. The unique geometry of smartFLOW Helix eliminates these effects. The targeted mixing of the melt in the nozzle area promotes uniform material distribution, which minimises injection defects and improves the visual quality of the items.
Rheologically designed flow channels and diffusion-welded manifolds
In addition to its specialised flow technology, Meusburger uses diffusion-welded hot runner manifolds, which ensure uniform melt flow thanks to their rheological design. This is optimally aligned with the flow properties of the plastics. Diffusion welding enables the creation of complex channel layouts with high dimensional accuracy and surface quality. This helps to reduce pressure losses and localised hotspots.
Added value for sophisticated applications
Meusburger recommends smartFLOW Helix particularly for frequent colour changes, applications with high visual quality requirements, multi-cavity moulds and technical plastics. Improved homogenisation of the melt helps to ensure consistent part quality and stable processes. The technology also offers advantages in standard applications: Consistent filling reduces the risk of unusable parts and improves process reliability in serial operation.
