Development of High-Pressure Die-Casting Simulation and Verification in Motorcycle Parts

Article of Honda R&D Technical Review Vol.17 No.2

Summary

The quantitative evaluation of trapped air and strength of cast products at the completion of solidification in high pressure die-cast has been studied using material test and simulation. As a result, the prediction accuracy of trapped air analysis was enhanced by considering back pressure. In addition, by coupling the trapped air defect at the completion of flow with the solidification process, the analysis of mechanical characteristics of cast products has become possible.
