According to the company, the innovation lies in the 3D-printed air spaces that provide insulation to the nozzles from the mold, ensuring a consistent temperature profile. This capability facilitates the processing of challenging materials within narrow temperature windows, while simultaneously reducing energy consumption and heat input into the injection mold, enabling more economical and sustainable part production.

Nozzles are delivered at the optimal length for a specific mold design at no additional cost and each nozzle is distinctively produced to seamlessly integrate with the mold, including an imprinted union nut to simplify installation and maintenance.

In addition, the hot runner manifold supports are made with insulation through the SLM process, branded as Energy Blockers. This enhancement leads to a 52% reduction in overall system energy consumption compared to conventional hot runner systems using titanium ceramic supports.

Witosa products are now available in the U.S. at DMS’ website.
