Al Alloys and Manufacturing Processes for Lightweight Applications in Electric Vehicles

Abstract. Due to increasing environmental concerns, battery-powered electric vehicles (BEV) have gained popularity in the automotive for the past few years. An induction motor is an essential component of the propulsion system in integrated BEVs working on different operating conditions [1]. Since a rotor of the induction motor is configured with an electrical sheet, a

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
