ABSTRACT:
An insert for a die casting assembly. The insert comprises a cast iron insert having a first end, a second end and a body disposed between the first end and the second end, the body having a pour aperture in communication with a pour hole of a shot sleeve. The insert is removeably positioned within a groove of the shot sleeve wherein the molten material that is dispensed from the pour hole and into the pour aperture initially contacts the cast iron insert when the molten material flows into the cast iron insert such that the cast iron insert withstands heat erosion effects applied by the molten material to provide a smooth path for the plunger as the plunger reciprocates within a sleeve bore of the shot sleeve and pushes the molten material into a mold cavity.
