摘要
Method and apparatus for improving the quality and mechanical properties of an aluminum alloy engine cylinder block or other large or complex castings by providing sand molds bound with a soluble binder only at locations on said casting from which rapid cooling for directional solidification and/or improved localized mechanical properties are desired with said molds being otherwise bound at the remaining locations only with a more typical insoluble binder.
