Abstract: A shot sleeve assembly for use in the high pressure die casting of aluminum silicon alloys containing 0.40% maximum Fe is also disclosed. The shot sleeve assembly includes a shot sleeve including a pouring hole and a bushing assembly. The bushing assembly includes a refractory metal tube constructed of erosion resistant material surrounded by a bushing of conventional tool steel. The tube includes an opening and an impingement site located opposite the opening. The bushing includes an opening aligned with the opening of the tube, and an end plate. The bushing assembly is readily removed and inserted into the shot sleeve such that the openings of the bushing assembly align with the pouring hole of the shot sleeve. A method of replacing an impingement site of a shot sleeve with an erosion resistant material is also disclosed.

Abstract: An improved shot sleeve for high pressure die casting of low-iron aluminum silicon alloys and a method of making the shot sleeve, the shot sleeve includes a top portion including a pouring hole and a bottom portion including an impingement site on an inner surface of the bottom portion opposite the pouring hole. The impingement site is constructed of an erosion resistant material. The erosion resistant material is selected from: titanium, tungsten, molybdenum, ruthenium, tantalum, niobium, chromium, vanadium, zirconium, hafnium, boron or a secondary, tertiary or quaternary alloy formed from combination thereof. An erosion resistant insert located at an impingement site of a shot sleeve may accomplish the construction. The insert may be introduced into an internal surface of a conventional shot sleeve or replace a bottom portion of a conventional shot sleeve.
