Zusammenfassung:Methods for replacing an impingement site of a shot sleeve with an erosion resistant material, for manufacturing a shot sleeve for high pressure die casting of Aluminum Silicon alloys having an erosion resistant material at an impingement site, and for manufacturing a shot sleeve for high pressure die casting of aluminum silicon alloys containing 0.40% max Fe, having an erosion resistant material at an impingement site are disclosed. The shot sleeve assembly includes a shot sleeve including a pouring hole and a, impingement site. In certain embodiments a bushing assembly is implemented. The impingement site or bushing assembly includes a refractory metal tube constructed of erosion resistant material.
