A most crucial aspect in permanent mould castings such
as die-casting or squeeze casting is the die itself and, most
importantly, the design of the die including the selection of a
suitable die material, the manufacturing process, appropriate
heat treatment and the maintenance practice. Squeeze casting
dies are exposed to severe thermal and mechanical cyclic
loading, which may cause thermal fatigue, cracking, erosion,
corrosion, and indentation. The nature and features of a
die are greatly in¯uenced by the particular alloy to be cast.
