Haidlmair Group has created FDU Hotrunner GmbH to distribute and develop the company's FDU(flat die unit),which originally launched at K 2016.At K 2019,FDU Hotrunner will introduce a new valve-gate nozzle,the FDU SLS(Slot Lock System).Building on the company's blade closure shutoff technology,the FDU SLS features a guide system with anti-twist protection for the blade that doesn't divide the melt flow.Through this,cross sections up to 175 mm~2 exit area and large shot volumes can be injected without stress or shear at high speed.This also means lower injection pressures can be used than with the conventional FDU,without jetting and consistent fill and hold.The company says the first iteration of the FDU achieved cycle time reductions up to 25%,with even more possible using the SLS version.At the show,a mold utilizing the new nozzle will be running on a KraussMaffei injection machine making a container.Additional Haidlmair molds will be in action at the booths of Erema,Woojin,Eneel and Sumitomo Demag.
