The CAD/CAE Technology of Electromagnetic Low Pressure Die Casting for Aluminum Alloys

The CAD/CAE technology of electromagnetic low pressure casting for aluminum alloys was proposed. The CAD/CAE model was established based on the study of export pressure determination method of electromagnetic pump, the pressurization criterion design technology, velocity initial condition and predication method of shrinkage and porosity of low pressure die casting process. Also the filling and solidification were simulated in low pressure casting process. The results of experiment and simulation show the exportation pressure of the electromagnetism pump can be regulated and controlled accurately by controlling the electric current and the defect predication considering the pressure condition is more accurate. The filling of electromagnetism pump low pressure casting is steady, and the pressurization control is precise. The electromagnetism pump low pressure casting is the advanced casting method to produce high quality aluminum castings.
