In high pressure die casting, where speed of the melt during die filling is very high, cavitation is one of the major causes of die erosion. Form S.r.l. as die constructor is sensible to this problem and decided to go deeper in the analysis of a real case where cavitation leads to premature die erosion. The cavitation model of Flow3d-cast was used to analyze this phenomenon. Then a solution was introduced by changing the geometry of the gate and tested in production. This work has been presented by FORM in Krakow, at the Flow3D European User Meetings 2016.
