Abstract

This paper presents modeling and control of fluid pressure inside a mold in a press casting process using greensand molding as an innovative casting method. The defect-free manufactures of casting product in the press process are very important problem. Then, it is made clear that the press velocity control achieves to reduce the rapid increase of fluid pressure. A mathematical model of the molten metal’s pressure in a casting mold is built by using a simplified mold and investigated the availability by comparison with the CFD model. A pattern of the press velocity from the high speed to the lower speed is derived by using the mathematical model. Finally, the effectiveness of the proposed switching velocity control has been demonstrated through CFD computer simulations.
