N/A Front housings(a part for automobile) were die cast using ADC12 alloy by various die casting techniques such as ordinary die casting(OD), squeeze casting(SQ) and partial squeeze-pore free die casting(POD). Casting defects of those front housings and their mechanical properties were examined and compared. Casting defects such as blowholes and pinholes normally formed in OD method were eliminated by applying SQ or POD techniques. Tensile strength and elongation of die casting produced by SQ or POD techniques were 1.4 and 2.6 times higher than that of ordinary die castings. Tensile strength and elongation of ADC12 alloy front housings produced by SQ or POD techniques were increased by T6 treatment up to 38㎏/㎟ and 2.7 % respectively.
