At next month’s Fakuma show in Friedrichshafen, Germany, HRSflow of Italy (U.S. office in Byron Center, Mich.) will show off a new family of screw-in hot-runner nozzles for small, delicate parts such as loudspeaker grilles and for reverse gating from the ejector side. Thanks to a space-saving heating system, the nozzle-seat diameter has been reduced from 33 to 28 mm over the entire length. Nozzle lengths range from 75 to 450 mm with internal diameters of 6, 8, and 10 mm. They are offered with one or two heating zones and in Classic Line and Fail Safe versions—the latter with two heaters and thermocouples. Gating options include torpedo, free-flow, and valve gating.
