Hasco: “Streamrunner” reduces energy demand and enables more compact injection moulds

At Fakuma 2026, Hasco highlighted the potential for reducing energy consumption and optimising mould design in injection moulding with its additively manufactured “Streamrunner” hot runner manifold. According to the company, the manifold’s energy demand can be reduced by up to 85% compared with conventional designs. At the same time, its compact construction is intended to enable smaller moulds and, in certain applications, the use of smaller injection moulding machines.

Compact design for higher cavity density
The “Streamrunner” is designed for nozzle spacings from 18 mm. This allows more cavities to be arranged within the same mould area or the overall external dimensions of the mould to be reduced. The minimum installation height is 26 mm. This makes it possible to make better use of the available installation space, particularly in applications where mould dimensions are limited.

Additive manufacturing also enables flexible manifold geometries, including unusual cavity numbers and nozzle arrangements. In family moulds, the melt flow can be rheologically balanced. Depending on the application, reducing the size and weight of the mould may also make it possible to use a smaller injection moulding machine, which can further influence the energy requirements and overall costs of the process.

Flow design for sensitive materials and colour changes
According to Hasco, the manifold channels are designed for optimised flow and feature smooth surfaces with no dead zones. This is intended to reduce material deposits and shear stress on the polymer melt. This is particularly relevant for frequent colour changes and for processing temperature-sensitive or otherwise sensitive polymers. For applications involving corrosive plastics, the standard manifold is made of corrosion-resistant steel.

The “Streamrunner” is available in dimensions of up to 300 mm x 300 mm. Its technical features are primarily aimed at reducing energy demand in the hot runner system, enabling more compact mould designs and providing greater geometric flexibility in the design of injection moulding tools.
