Easy maintenance


An exchange of the tip inserts is easily possible from the moulds parting line. After removing the cover flange the tip insert to remove is deinstalled in a tilting movement and the new tip insert is installed. The cover flange is positioned again and presses the fitted insert against the nozzle. The necessary sealing force between the tip insert and nozzle body is generated by an oblique surface in the nozzle body/tip insert and is defined by the tightening torque of the screws of the cover flange. A leak-proof sealing between tip insert and mold insert is ensured by the thermal expansion of the nozzle body and tip insert. By this method even angled tips can be fitted without problem into the corresponding undercut geometries of the mold insert.
