The computer simulation of an high pressure die casting process has reached today – with the right tools – a very high degree of accuracy, to the extent that it is possible to forecast the process that it is going to be realized in every its detail.

Manipulations like rotations, zoom, going forward/backward along the time to better identify the exact time and location of a defect, are all very easy operations to do with modern calculators.

Users can then improve their dies or casting parameters before the real cast piece is realized, correcting every imperfection until an optimal filling is reached.

XC Engineering has a large know-how on this application, and provide consultancy services as well as the right software for HPDC simulation (FLOW-3D Cast).

At the end of each calculation it is possible to extract information like:

• defects captured during the filling process, like oxides or air entrainment
• metal dynamics inside the shot sleeve
• metal velocities at significant locations, like the gating system
• filling time
• porosities and shrinkages
• solidification front
• stress and deformations analysis
• cooling channels efficiency

and a lot more.
