  • 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.

  • Sand casting Wikipedia

    Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries.Over 60% of all metal castings are produced via sand casting process.

  • The Different Methods of Core Making Tinker Omega

    Oct 04, 2013· Shell core making is a method where sand is pre-coated with resin and then poured into a pre-heated core box. No catalyst is used in this process and instead heat is introduced in the surface of the box until it forms a thin, hard shell. This allows the sand on the inside of the core to remain uncured and removed by pouring it out from the core
