The horizontal cold chamber pressure die casting produces a wide range of near-net shape, complex-geometry castings with desired mechanical properties, tight dimensional tolerance, and surface finish. However, top quality castings can be achieved only when optimal performance of the cold chamber (shot sleeve) and plunger is maintained. Unfortunately, in reality, shot sleeves deteriorate fast and sometimes fail catastrophically due to incorrect design. To prevent premature failures of shot sleeves major failure mechanisms were investigated, and robust design criteria were developed. The data directly obtained from failed shot sleeves in US die casting industry support a strong correlation between design and failures as suggested.
