This work of thesis has been developed in collaboration with the companies STCast S.r.l. e F.O.M.T. S.p.a. and it focuses on analyzing the gravity mold casting process for an aluminum casting alloy component, which is destinated for use in internal combustion industrial vehicles as an engine oil pan. The part has a moderately complicated geometry that ends up causing a particularly critical defect during its manufacturing process, which this thesis work focuses to solve. The work prevalently consisted in experimental research, analizying the effects of different experimental approaches to the production run of this particular product in order to solve its manufacturing problems, analizying both at the macroscopic and microscopic level some samples from the different experimental production runs and comparing their microstructures in order to validate the different results.
