Abstract

Partial squeeze die casting is a special die casting process which combines squeeze technique to conventional die casting. The influence of squeeze pressure $(1500-3000kg/cm^2)$ and time-lags(0.5-2.0sec) on defect control, density and microstructure of ADC12 alloy die casts has been studied by appling partial squeeze die casting to air compressure front housing production. Defect free, maximum density of $2.736kg/cm^3$ with sound microstructure of ADC12 alloy die cast has been obtained by partial squeeze die casting technique at the pressure of $2000-2500kg/cm^2$ and time-lags of 1.0-2.0sec.
