Coremaking: Life of a Casting Reliance Foundry

Cores create flexibility in sand casting. The ability to make and place sand cores is a vital part of the casting process. In some instances, the core is necessary for the utility of the final part: tubes, engines, and other mechanical devices often need to be hollow to work. For decorative items, cores can also cut down on the total cost of metal.
