A Simulation and Fabrication Works on Optimization of High Pressure Aluminum Die Casting Part

Abstract

High-pressure die casting oers reduced costs due to its small tolerances and smooth surface nish. Casting parts produced are consumed by the automotive industry in millions. In this study, the use of computer aided engineering applications on design of high-pressure die-casting was studied. The inuence of casting process steps in die design was studied and analyzed. The casting simulation software was used to improve design and solve problems. By using the simulation software in analyses of die design, the nal design was reached in a few hours and thus the design process of pre-production was shortened and mold production was carried out with no revision on die material. Radiographic test was applied on the casting parts and the result shows good correlation between simulations of solidication result data. Also the results proved that the application of squeeze pressure in the intensication phase of high-pressure die casting process could be examined in the casting simulation.

Performance Evaluation of Different Air Venting Methods on High Pressure Aluminum Die Casting Process

“…These systems can be used both as a vent and as a vacuum valve. Wang's study showed that [8][9][10], 3D venting systems, when used as a vent, is more efficient than a conventional chill vent which connected to a vacuum system, and can achieve nearly the same evacuation efficiency as the best available from a simple vacuum system. In another study, Wang et al [8] showed that 3D venting systems, when used in the die casting process, then the machine downtime which is caused by vacuum defects has been reduced.…”
