  • Sodium Silicate for Making Foundry Cores

    Sodium Silicate is used as the binder that "glues" the sand together in cores. For example, imagine making a cannon. The bore (hollow section) of the cannon can be formed by a core. The hardened sand core goes into the cannon mold so that the molten metal will form the cannon body, but be blocked from filling the center. After the metal cools

  • Sand Casting Explained Metal Technologies

    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. The molten metal solidifies in the cavity between the interior of the mold and the exterior of the core. There are the five basic steps to creating a sand casting

  • 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.
