Abstract

Effects of die design and processing parameters on control arm of automobile in squeezing casting have been investigated.The optimization of processing parameters

such as the sectioned width of ingate

composition and pressure

has been paid attention to.The experimental results indicate that the control arm with sound microstructure and fine grain size whose mechanical properties approach to those of forging parts can be produced with sectioned width of 10mm and specific pressure of 50 MPa and Fe content less than 0.1%.
