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 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.
