A heuristic approach to meet geometric tolerance in High Pressure Die Casting

A heuristic approach to meet geometric tolerance in High Pressure Die Casting

G.CampatelliA.Scippa Abstract In High Pressure Die Casting (HPDC), geometrical distortions usually happen during the cooling phase, due to the reduced cooling time and the high thermal gradient inside the product itself. This phenomenon affects most the thin walled products. The usual die design practice considers only the linear shrinking of the product during the cooling as a consequence of
