Shrinkage Porosity in Die Casting

The reason of shrinkage porosity is that shrinkage happen when melted alloy turn into solid from liquid.The casting become solid from inner to outer,therefor,there will be shrinkage porosity if wall thickness of casting is big. All above,it is really impossible to fully solve the gas porosity for casting that have big wall thickness. shrinkage porosity To remove shrinkage porosity,it necessary to decrease thermo joint of casting and fillet edge of casting.The uniform wall thickness of casting is necessary as well.The joint between [...]
