Flat die unit (FDU) Haidlmair's latest device is an open hot-runner nozzle system for injection molds. The FDU combines the conventional round nozzle used in injection molding with the channel geometry of a flat die for extrusion, allowing the resin to flow evenly into the cavity through a long, narrow gap.
What's new? U.S. availability. Introduced at the K show, the units recently became available in the U.S. market.
Benefits Dramatically shorter cycle times, reduced energy consumption and less shear. The FDU's geometry can reduce the shear in the nozzle by as much as half. Also, for some materials, such as PP, the FDU can lower injection pressures.
