Description

     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. They help reduce cooling times and produce more rigid sprues. Rigidity is important since the sprue is often the point at which pickers or other industrial robots grasp molded parts for removal.
     The internal aperture of the sprue bushing is tapered, which facilitates removal of the sprue from the mould at the end of moulding cycle.
     Different country standards of sprue bushes are provided: Japanese, European and Chinese standard.
