A new additively manufactured hot runner from Hasco eliminates sharp edges and sections with poor through-flow properties. The Steamrunner leads to lower shear rates and improves the quality of the molded parts. Colour changes can also be carried out faster via the flow-optimized design because the material can be guided via large deflection radii.

The free three-dimensional design of the hot runner creates new possibilities in multi-component injection molding, according to Hasco. Various plastic components or colors can be distributed over a very small space and the runners can be intertwined.

The technology allows very small nozzle gaps. Depending on nozzle size, cavity-to-cavity distances can start at 18 mm. The manifold height can also be sized 20 to 30 mm lower than with conventional manifold blocks.

As with all other hot runner systems from Hasco, the Streamrunner can be adapted for specific applications and is available as a fully wired modular system or assembled hot half with precisely coordinated control technology.

The Steamrunner’s compact design accommodates small mold sizes and, thus, smaller injection molding machines than other hot runners. In addition, the manifold block’s low mass reduces energy consumption.
