    Sand Casting Explained Metal Technologies

    Metal casting is the process in which molten metal is poured into a mold and allowed to solidify into an object. The object that results from this process is also called a casting. In sand casting, sand is used to define the cavity inside a mold. In addition, sand is used to make any cores that are contained in the mold.

  • Comparing Sand Additives in Steel CastingsModern Casting

    Dec 15, 2021 · When molten steel is poured into a chemically bonded sand mold to produce a casting, heat moves rapidly from the liquid metal into the surface of the sand and produces steep thermal gradients. As a result, the sand grains will expand and the organic binder in the mold will pyrolyze, producing carbon monoxide and other gasses that can cause defects.
