A Sprue is a channel through which to transfer molten plastic injected from the nozzle of the injector into the mould. It is a part of Sprue bush, which is a separate part from the mould.
The Sprue bush is the connecting member between the machine nozzle and the mould face, and provides suitable aperture through which the material can travel on its way to the mould cavity or the start of the runner system in multi-impression moulds.
